Port Adapter Overview

The PA-MC-2T3-EC is a single-width port adapter that provides two T3 interface connections using BNC connectors. (See Figure 1-2.) The PA-MC-T3-EC provides one T

3 interface connection using BNC

connectors. (See Figure 1-1.) Hereafter, both versions of this port adapt

er will be referred to as the

PA-MC-TE-EC. A channelized T3 provides 28 T1 lines multiplexed into the T3.

The PA-MC-T3-EC supports the following hardw

are accelerated features.

• Multilink PPP (MLPPP)

• Multilink Frame Relay (FRF.16)

• Frame Relay Fragmentation (FRF.12)

For more information on the features, and restrictions, see Chapte

r 5, “Configuring the Channelized

Mode.”

Chapter 1 Overview

Channelized T3 Overview

Figure 1-2 PA-MC-2T3-EC—Front Panel

The PA-MC-T3-EC has the following features and physical characteristics:

• The PA-MC-T3-EC supports channelized operations.

• The PA-MC-T3-EC transmits and receives data bidirectionally at the T3 rate of 44.736 Mbps.

• The PA-MC-T3-EC conforms to relevant specifications for Digital Signal Level 3 (DS3) circuits.

• The T3 connection, provided by two female BNC connectors for transmit (TX) and receive (RX),

requires 734A coaxial cable that has an impedance of 75 ohms.

• The PA-MC-T3-EC supports RFC 1406 and RFC 1407 (CISCO-RFC-1407-CAPABILITY.my). For

RFC 1406, Cisco supports all tables except the FarEnd table. For RFC 1407, Cisco does not support FarEnd or Fractional tables. (For information on accessing Cisco MIB files, refer to the Cisco MIB User Quick Reference publication.)

• PA-MC-T3-EC microcode is loaded at initialization and is bundled into Cisco IOS software.

Note The PA-MC-T3-EC does not support E1 into channelized T3.

Channelized T3 Overview

In the channelized mode of operation, a PA-MC-T3-EC T3 link is channelized into 28 DS1 data lines in an industry standard multiplexing format.

Each of the T1 lines contains 24 time

slots of 64 or 56 kbps each. The T1 lines can support one or more user data channels which appear to the system as serial interfaces. Each serial interface is assigned one or more of the time slots giving the serial interface a bandwidth of n x 56 kbps or n x 64 kbps, where n is the number of time slots assigned. Any unused time slots of the T1 are filled with an idle channel pattern.

The following restrictions apply: A time slot can only be used by one serial interface. A serial interface canno

t use time slots from more than one T1 line. Each T3 line can have a maximum of 128 serial

interfaces. Unused serial interfaces on one T3 cannot be used by the other T3 line.

The PA-MC-T3-EC supports Cisco High-Level Data Link Control (HDLC), Frame Relay, PPP, and Switched Multime

gabit Data Service (SMDS) Data Exchange Interface (DXI) encapsulations over each

serial interface.

Note T1 lines on the PA-MC-T3-EC are numbered 1–28, rather than the more traditional zero-based scheme

(0–27) used with other Cisco products. This is to ensure consistency with telco numbering schemes for T1 lines within channelized T3 equipment.

Chapter 1 Overview

Unchannelized T3 Overview

Note The PA-MC-T3-EC does not support the aggregation of multiple T1 lines (called inverse multiplexing

or bonding) in hardware for higher bandwidth data rates. MLPPP may be used for this purpose in software.

The T3 section of the PA-MC-T3-EC supports the maintenance data link (MDL) channel when using c-bit parity framing as well as local and network loopbacks. The T1 section of the PA-MC-T3-EC supports facilities data link (FDL) in Extended Superframe (ESF) framing, as well as various loopbacks. Bit error rate (BER) testing is supported on each of the T1 lines, although a test may not be active on more than one T1 line at a time. BER testing may be done over a framed or unframed T1 signal.

Unchannelized T3 Overview

In the unchannelized mode of operation, a T3 link provides a single high speed user data channel, rather than being multiplexed into 28 T1 lines. The data channel appears to the system as a serial interface that may be configured to use the full T3 bandwidth or a smaller portion of the T3 bandwidth. No industry standard exists for subdividing the T3 bandwidth, but the PA-MC-T3-EC is compatible with the proprietary formats of five vendors of data service units (DSUs), when used at the far end of the T3 link.

In unchannelized T3 mode, the T3 section sports the maintenance data link (MDL) channel when using c-bi

t parity framing as well as local and network loopbacks. Bit error rate (BER) testing is supported on the T3 link. The PA-MC-T3-EC supports Cisco High-Level Data Link Control (HDLC), Frame Relay, PPP, and Switched Multimegabit Data Service (SMDS) Data Exchange Interface (DXI) encapsulations over the serial interface.

T3 Specifications

The PA-MC-T3-EC T3 port is designed to receive and transmit at the DSX-3 level while driving and receiving from 75-ohm coaxial cables (ATT 734A or equivalent quality coaxial cable). The T3 port connects directly to any equipment with DSX-3-level BNC connectors.

Table 1-1

lists the specifications that the T3 front end is designed to meet.

Note The coaxial shield side of the T3 BNC connectors is connected to the router chassis ground.

Identifying Interface Addresses

This section describes how to identify the interface addresses used for the PA-MC-T3-EC in Cisco 7200 VXR routers. Interface addresses specify the actual physical location of each interface on a router or switch. The interface address is composed of a two-part number in the format

port-adapter-slot-number/interface-port-number.

Interfaces on the P

A-MC-T3-EC installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Note Interface ports are numbered from left to right starting with 0.

Identifying Interface Addresses

Table 1-2 explains how to identify interface addresses

In Cisco 7200 VXR routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. (Port adapt

er slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.)

The interface addresses of the inte

rfaces on the PA-MC-T3-EC in port adapter slot 1 are 1/0 and 1/1 (port

adapter slot 1 and interfaces 0 and 1). If the P

A-MC-T3-EC was in port adapter slot 4, these same

interfaces would be numbered 4/0 and 4/1 (port adapter slot 4 and interfaces 0 and 1).

Safety Guidelines

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not work alone when potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe;

carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules comprise printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

Page 27

PA-MC-T3-EC Port Adapter Installation and Configuration

OL-10589-02

Chapter 2 Preparing for Installation

FCC Class A Compliance

• When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

• When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

• Place a removed board component-side-up on an antistatic surface or in a static shielding container.

If you plan to return the component to the factory, immediately place it in a static shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms (Mohm).

FCC Class A Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

You can determine whether your equipment is causing interference b

y turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is,

make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Note The Cisco PA-MC-T3-EC port adapter has been designed to meet these requirements. Modifications to

this product that are not authorized by Cisco Systems, Inc. could void the various approvals and negate your authority to operate the product.

Removing and Installing Port Adapters

This chapter describes how to remove the Cisco PA-MC-T3-EC port adapter from the supported platform and also how to install a new or replacement port adapter. This chapter contains the following sections:

• Handling Port Adapters, page 3-2

• Online Insertion and Removal, page 3-2

• Warnings and Cautions, page 3-3

• Port Adapter Removal and Installation, page 3-4

• Cisco 7201 Router—Removing and Installing a Port Adapter, page 3-6

Note When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router or

switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove the blank port adapter.

Caution When powering off the router, wait a minimum of 30 seconds before powering it on again.

Chapter 3 Removing and Installing Port Adapters

Handling Port Adapters

Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.

Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components

or connector pins. (See Figure 3-1.)

Figure 3-1 Handling a Port Adapter

Online Insertion and Removal

The Cisco 7200 VXR platform supports online insertion and removal (OIR) of port adapters; therefore, you do not have to power down routers when removing and replacing a PA-MC-T3-EC in Cisco 7200 VXR routers.

Note As you disengage the module from the router or switch, online insertion and removal (OIR)

administratively shuts down all active interfaces in the module.

It is wise to gracefully shut down the system before removing a port adapter that has active traffic moving through it. Removing a module while traffic is flowing through the ports can cause system disruption. Once the module is inserted, the ports can be brought back up.

Note After removing a PA-MC-T3-EC, wait 3 minutes before reinstalling or reinserting a PA-MC-T3-EC.

Note Online insertion and removal (OIR) is not supported on the Port Adapter Jacket Card. OIR is supported

on the port adapter. You must have the chassis powered off to install or remove the Port Adapter Jacket Card.

Chapter 3 Removing and Installing Port Adapters

Warnings and Cautions

OIR allows you to install and replace modules while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the module you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

The following is a functional description of OIR for background information only; for specific p

rocedures for installing and replacing a module in a supported platform, refer to the “Port Adapter

Removal and Installation” section on page 3-4.

Each module has a bus connector that connec

ts it to the router. The connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the module. The system assesses the signals it receives and the order in which it receives them to determine if a module is being removed from or introduced to the system. From these signals, the system determines whether to reinitialize a new interface or to shut down a disconnected interface.

Specifically, when you insert a module, the longest pins make contact with the module first, and the shortest pins

make contact last. The system recognizes the signals and the sequence in which it receives

them.

When you remove or insert a module, the pins send si

gnals to notify the system of changes. The router

then performs the following procedure:

1. Rapidly scans the system for configuration changes.

2. Initializes newly inserted port adapters or administratively shuts down any vacant interfaces.

3. Brings all previously configured interfaces on the module back to their previously installed state.

Any newly inserted interface is put in the administratively shutdown state, as if it was present (but not configured) at boot time. If a similar module type is reinserted into a slot, its ports are configured and brought online up to the port count of the originally installed module of that type.

Note Before you begin installation, read Chapter 2, “Preparing for Installation,” for a list of parts and tools

required for installation.

Warnings and Cautions

Observe the following warnings and cautions when installing or removing port adapters.

Note If a port adapter locking lever or other retaining mechanism does not move to the locked position, the

port adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter locking lever or other mechanism to the locked position.

Warning

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing.

Caution To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to

ensure that the edge connector at the rear of the port adapter mates with the connection at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the following illustration.

Chapter 3 Removing and Installing Port Adapters

Cables and Connectors

The interface connectors on the PA-MC-T3-EC are coaxial BNC types, with one connector for transmit (TX) and one for receive (RX). The BNC connectors are transformer-coupled to the PA-MC-T3-EC line interface unit (LIU), which is the analog physical interface on the PA-MC-T3-EC.

The pinout and signal descriptions for the BNC c

onnectors on the PA-MC-T3-EC are as follows:

• Transmit (TX)—Transmitted signals appear on the center contact, and the outer shield is grounded

for the 75-ohm 734A coaxial cable you attach to the TX BNC connector.

• Receive (RX)—Received signals appear on the center contact, and the outer shield is grounded for

the 75-ohm 734A coaxial cable you attach to the RX BNC connector.

Caution To prevent problems when long cable lengths are required, you must ensure that your 75-ohm coaxial

cables meet or exceed 734A specifications. See “T3 Specifications” section on page 1-3 for supported cable lengths.

Figure 3-5 shows the typical 75-ohm 734A coaxial cable pair recommended for use with the

PA-MC-T3-EC. Use one 75-ohm c

oaxial cable for each PA-MC-T3-EC connection: RX and TX.

Note Cisco Systems does not supply cables with the PA-MC-T3-EC. You must supply your own cables.

Figure 3-5 75-Ohm 734A Coaxial Cable Pair

Connecting the Cables

This section describes the procedure for attaching 75-ohm 734A coaxial cables between the PA-MC-T3-EC port adapter and your external DS3 equipment. To continue your PA-MC-T3-EC port adapter installation, you must install the port adapter cables. The instructions that follow apply to all supported platforms.

Connect the 75-ohm coaxial cables to the PA-MC-T3-EC as follows:

Step 1 Attach the 75-ohm coaxial cables directly to the BNC ports on the PA-MC-T3-EC. Attach one end of a

cable to the port labeled TX and one end of a second cable to the port labeled RX. (See Figure 3-6 on

page 3-9.)

Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) ins

tead of an angle bracket (>).

At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a

privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, t

he system displays the privileged-level system prompt (#):

Chapter 4 Configuring the Unchannelized Mode

Replacing an Existing Port Adapter

Before you remove or replace a port adapter, use the shutdown command to disable the port adapter to prevent anomalies when you remove and reinstall the port adapter. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the “Using

the EXEC Command Interpreter” section on page 4-2 for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the

source of the configuration subcommands, as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Step 3 Shut down the T3 controller on the PA-MC-T3-EC with the controller shutdown command.

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with th

e no shutdown controller command.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# shutdow

Router(config)# controller T3 1/1 Router(config-controller)# shutdow

Note Both T3 ports of the PA-MC-T3-EC should be shut down before removing the port adapter.

Step 4 Verify that the two T3 ports are now shut down using the show controller T3 command:

The following example is for a PA-MC-T3-EC in port adapter slot 6 of a Cisco 7200 VXR router:

Router(config-controller)# end Router# s

how controller T3 6/0

T3 6/0 is administratively down.

Router# s

how controller T3 6/1

T3 6/1 is administratively down.

Step 5 Save the shutdown configuration to nonvolatile memory.

Router# copy running-config startup-config

Step 6 Replace the port adapter in the slot. See the “Port Adapter Removal and Installation” section on page 3-4

for more information.

Step 7 Re-enable the port adapter by doing the following:

a. Repeat Step 3 to re-enable an interface, but substitute the no shutdown command for the shutdown

command.

b. Repeat Step 4 to verify that the interfaces are in the correct state and no longer shut down. Use the

show controller T3 command

c. Repeat Step 5 to write the new configuration to memory.

Use the copy running-conf

ig startup-config command.

For complete descriptions of software configuration commands, refer to the publications listed in the

“Related Documentation” section on page iv.

Configuring an Unchannelized T3 Link

If you installed a new PA-MC-T3-EC or if you want to change the configuration of an existing PA-MC-T3-EC link, you must enter the privileged level of the EXEC command interpreter and then use the configure command. If you replace a PA-MC-T3-EC that was previously configured, the system recognizes the new PA-MC-T3-EC link and brings it up in its existing configuration.

After you verify that the new PA-MC-T3-EC is instal

led correctly (the ENABLED LED goes on), use

the privileged-level configure command to configure the new interface. Be prepared with the information you need, such as the following:

• Protocols you plan to route on each new interface

• IP addresses, if you plan to configure the interfaces for IP routing

The conf

igure command requires privileged-level access to the EXEC command interpreter, which

usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access.

Selecting a T3 Controller

You must enter the following controller command, before any other configuration commands, to select the T3 controller you want to configure:

controller T3 ch

assis-slot/T3-port

The example that follows is for a port adapter in slot 1 of a C

isco 7200 VXR router:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t3 1/0 Router(config-controller)#

Setting Unchannelized Mode for the T3 Controller

To configure the T3 for unchannelized mode, use the no channelized command. After the full-rate T3 interface is configured, use the dsu bandwidth command to create a subrate T3 interface. The following example configures a subrate T3 interface on a PA-MC-T3-EC in port adapter slot 1 of a Cisco 7200 VXR router:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t3 1/0 Router(config

-controller)# no channelized Router(config-controller)# exit Router(co

nfig)# interface serial 1/0

Router(co

nfig-if)# dsu bandwidth 16000

Router(co

nfig-if)# encapsulation frame-relay

Router(co

nfig-if)# ip address 10.10.10.10 255.255.255.255

Router(co

nfig-if)# no shutdown

When the PA-MC-T3-EC is configured for unchannelized T3 mode, its default MTU size is set to 4470 for compatibility with other T3 equipment and port adapters.

Setting the T3 port to unchannelized mode creates a serial in

terface that the following commands may

be used to configure. Use the interface serial command to select the serial interface.

Router# configure terminal Router# interface serial 1/0/1 Router(co

nfig-if)#

Setting the Framing Type for the Serial Interface

In interface configuration mode, specify T3 framing by entering the framing {c-bit | m13} configuration command where:

• c-bit is—c-bit parity DS3 framing.

• m13 is—M13 Multiplex DS3 framing.

Use the

no form of this command to return to the default, c-bit framing.

Specifying the Cable Length for the Serial Interface

At the prompt, specify the cable length using the cablelength feet interface command where:

• feet is a numeral from 0 to 450.

• The default value is 10 feet.

An example follows:

Router(config-if)# cablelength 40

Note For the cablelength feet command, user-specified T3 cable lengths are structured into ranges as follows:

0–49 and 50–450 to represent short and long cables.

If the numerical value entered by the user falls within the lower range, then the PA-MC-T3-EC T3 port is set for short cable output levels. If the value falls into higher range, the long cable output levels w

ill be used.

In the preceding example, a cable len

gth of 40 is specified, which means that the 0–49 range is used. If you change the cable length to 45, then the 0–49 range still applies. Further, if you specify a cable length of 100 or 200, the 50–450 range applies in both cases. Only moving from one range (0–49) to the other range (50–450) has an effect. The actual cable-length number you enter is stored in the configuration file. It is recommended that the actual cable length be entered to ensure future compatibility.

Setting the Clock Source for the Serial Interface

At the prompt, set the internal or line clock source for the selected T3 controller with theclock source {line | internal} interface command where:

• line selects a network clock source.

• internal selects an internal clock source.

The default is clock source internal.

Examples follow:

• Instruct the PA-MC-T3-EC to use a line clock source.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# interface serial 1/0 Router(config-if)# clock source li

• Instruct the PA-MC-T3-EC to use an internal clock source.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# interface serial 1/0 Router(config-if)# clock source in

Configuring an Unchannelized T3 Link

Configuring MDL Messages for the Serial Interface

You can configure maintenance data link (MDL) messages (which are defined in the ANSI T1.107a-1990 specification) on the PA-MC-T3-EC.

Note MDL messages are only supported when the T3 framing is set for c-bit parity. (See the “Setting the

Framing Type for the Serial Interface” section on page 4-5.)

To configure MDL messages, use the mdl {transmit {path | i

dle-signal | test-signal} | string {eic | lic

| fic | unit | pfi | port | generator} string

} interface commands where:

• eic is the equipment identification code (up to 10 characters).

• lic is the location identification code (up to 11 characters).

• fic is the frame identification code (up to 10 characters).

• unit is the unit identification code (up to 6 characters).

• pfi is the facility identification code to send in the MDL path message (up to 38 characters).

• port is the equipment port, which initiates the idle signal, to send in the MDL idle signal message

(up to 38 characters).

• generator is the generator number to send in the MDL test signal message (up to 38 characters).

Use the no fo

rm of this command to remove MDL messages. The default is that no MDL message is

configured.

Examples of MDL Message Configuration

Examples of configuring MDL messages follow:

• Enter interface configuration mode first.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface serial 1

Router(config-if)#

• Enable the MDL path message transmission as follows:

Router(config-controller)# mdl transmit path

• Enable the MDL idle signal message transmission as follows:

Router(config-if)# mdl transmit idle-signal

• Enable the MDL test signal message transmission as follows:

Router(config-if)# mdl transmit test-signal

• Enter the equipment identification code as follows:

Router(config-if)# mdl string eic router A

• Enter the location identification code as follows:

Router(config-if)# mdl string lic tst network

• Enter the frame identification code as follows:

Router(config-if)# mdl string port string

• Enter the generator number to send in the MDL test signal message as follows:

Router(config-if)# mdl string generator string

Setting the DSU Mode for the Serial Interface

In interface configuration mode, define the data service unit (DSU) interoperability mode by entering the dsu mode [0 | 1 | 2 | 3 | 4] con

figuration command, as in the following example:

Router(config-if)# dsu mode 1

Use the no form of this command to return to the default, 0.

The local DSU mode must match the remote DSU or T3 port configuration. For example, if an ADC K

entrox DSU is at the remote end of the T3 link, then the local T3 port must be configured for mode 1.

You need to know what type of DSU is at the remote T3 end t

o find out if it interoperates with the PA-MC-T3-EC. Specify mode 0 for connection from a PA-MC-T3-EC to another PA-MC-T3-EC or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-MC-T3-EC to a Kentrox DSU. Specify mode 2 for connection from a PA-MC-T3-EC to a Larscom DSU. See Tabl e 4-1 for a list of DSUs and their corresponding bandwidth ranges.

Note If the far-end DSU has more than one DTE (HSSI) port, connect to and configure only DTE#1. See

Caution below for Verilink DSUs.

Caution Always connect to and configure HSSI port B on the Verilink HDM 2182. Port A is not supported by the

PA-MC-T3-EC.

Chapter 4 Configuring the Unchannelized Mode

Configuring an Unchannelized T3 Link

Caution The PA-MC-T3-EC does not support the Kentrox DSU bandwidth setting of 1.0 mbps. The Kentrox DSU

speed must be set to 1.5 mbps or greater.

Caution For all DSU modes, the DSU must be configured for the same transmit and receive speeds. Asymmetrical

transmit and receive speeds are not supported.

Setting the Bandwidth for the Serial Interface

In interface configuration mode, set the bandwidth to be used by the serial interface on the T3 link by entering the dsu bandwidth bandwidth configuration command, as in the following example:

Router(config-if)# dsu bandwidth 16000

The allowable bandwidth range is 1 to 44210 kbps. Use the no form of this command to return to the default, 44210.

The local DSU bandwidth value must match the remote DSU

or T3 port bandwidth exactly. For example, if you set the DSU bandwidth to 16000 on the local port, you must do the same on the remote DSU or T3 port.

Setting Scrambling for the Serial Interface

In interface configuration mode, enable serial interface scrambling by entering the scramble configuration command, as in the following example:

Router(config-if)# scramble

Use the no form of this command to restore the default value, disabled.

The local port configuration must match the remote DSU or T3 port configuration. For example, if you enabl

e scrambling on the local port, you must do the same on the remote DSU or T3 port.

Configuring Loopback Mode for the Serial Interface

With loopbacks, you can detect and isolate equipment malfunctions by testing the connection between the PA-MC-T3-EC interface and a remote device such as a CSU/DSU. Remote loopback sends a command to loop the T3 line at the far end. It can be used to diagnose problems with cables from the port adapter to the switching office. Network loopback loops the PA-MC-T3-EC T3 port back to the network, allowing the remote end to test the connection to the PA-MC-T3-EC.

Local loopback loops the PA-MC-T3-EC T3 port back to itself,

allowing it to be tested in isolation from

the T3 cables and remote T3 equipment.

The l

oopback command places an interface in loopback mode, which enables test packets that are

generated from the ping command to loop through a remote device and cables. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device or cables in the path of the loopback test.

You can configure the serial interface

for loopback modes using the loopback [local | network | remote]

interface command.

The default is no loopback.

To return the serial interface to its default unlooped condition, use the no for

m of the command.

Chapter 4 Configuring the Unchannelized Mode

Configuring an Unchannelized T3 Link

Table 4-2 provides examples of the loopback {local | network {line | payload} | remote {line | payload}}

command.

Configuring the T3 Controller to Enable Loopbacks

The PA-MC-T3-EC can be configured to respond to or to ignore remote T3 loopback requests sent to it from the far-end T3 equipment. The equipment customer loopback command enables the port adapter to respond to remote T3 loopback commands from the remote T3 equipment while the equipment network loopback command causes the port adapter to ignore remote T3 loopback commands.

Router(config)# controller T3 1/0 Router(config-controller)# equipm

ent customer loopback

Note Remote loopbacks are only available when you use c-bit parity framing.

Ta b l e 4-2 Using loopback Commands

Shutting Down the T3 Controller

You can shut down the T3 controller on the PA-MC-T3-EC with the shutdown controller comman.:

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with th

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# shutdow

Configuring a BER Test on the T3 Controller

Bit error rate test (BERT) circuitry is built into the PA-MC-T3-EC. With BER tests, you can test cable and signal problems in the field.

There are two categories of test patterns that can be generated

by the onboard BER test circuitry: pseudorandom and repetitive. The former test patterns are polynomial based numbers and conform to the CCITT/ITU O.151 and O.153 specifications; the latter test patterns are zeros or ones, or alternating zeros and ones.

A list of the available test patterns follows:

• Pseudorandom test patterns:

–

2^15 (per CCITT/ITU O.151)

–

2^20 (per CCITT/ITU O.151 non-QRSS)

–

2^23 (per CCITT/ITU O.151)

• Repetitive test patterns:

–

All zeros (0s)

–

All ones (1s)

–

Alternating zeros (0s) and ones (1s)

Both the total number of error bits received and the total number of bits received are available for analy

sis. You can set the testing period from 1 minute to 14,400 minutes (240 hours), and you can also

retrieve the error statistics anytime during the BER test.

When running a BER test, your system expects to receive the same pattern that it is transmitting. To acc

omplish this, two common options are available:

• Use a loopback somewhere in the link or network.

• Configure remote testing equipment to transmit the same BER test pattern at the same time.

Sending a BER Test Pattern on the T3 Line

You can send a BERT pattern on the T3 line with the bert pattern pattern interval time command in controller configuration mode where:

• pattern is one of the following:

–

0s, repetitive test pattern of all zeros (as 00000...)

–

1s, repetitive test pattern of all ones (as 11111...)

–

2^15, pseudorandom O.151 test pattern (32,768 bits long)

–

2^20, pseudorandom O.151 non-QRSS test pattern (1,048,575 bits long)

–

2^23, pseudorandom O.151 test pattern (8,388,607 bits long)

–

alt-0-1, repetitive alternating test pattern of zeros (0s) and ones (1s) (as 01010101)

• time is 1 to 14400 minutes.

Examples follow:

• Send a BERT pseudorandom pattern of 2^23 for 5 minutes.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# bert pa

ttern 2^23 interval 5

• Send a repetitive pattern of all ones for 14400 minutes (240 hours).

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# bert pa

ttern 1s interval 14400

Note You can terminate a BER test during the specified test period with the no bert command.

Viewing the Results of a BER Test

You can view the results of a BER test using the show controllers T3 slot/t3-port controller command.

You can view the results of a BER test at the following times:

• After you terminate the test using the no bert command

• After the test runs completely

• Anytime during the test (in real time)

The following table explains the output of the preceding command, line by line:

Output Display Line Explanation

BERT test result (running)

This line indicates the current state of the test. In this case, “running” indicates that the BER test is still in process. After a test is completed, “done” is displayed.

Test Pattern : 2^15, Status : Sync, Sync Detected : 1

This line indicates the test pattern you selected for the test (2^15), the current synchronization state (sync), and the number of times synchronization has been detected during this test (1).

Interval : 5 minute(s), Time Remain : 5 minute(s)

This line indicates the time the test takes to run and the time remaining for the test to run.

Interval : 5 minute(s), Time Remain : 2 minute(s) (unable to complete)

For a BER test that you terminate, this line indicates the time the test would have taken to run and the time remaining for the test to run had you not terminated it; “unable to complete” signifies that you interrupted the test.

Bit Errors(since BERT started): 6 bits,

Bits Received(since BERT start): 8113 Kbits

Bit Errors(since last sync): 6 bits

Bits Received(since last sync): 8113 Kbits

These four lines show the bit errors that have been detected versus the total number of test bits that have been received since the test started and since the last synchronization was detected. Bits and errors are only counted when the test status is “sync”.

Terminating a BER Test

You can terminate a BER test with the controller no bert command:

The following example terminates the B

ER test running on T3 line 0.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# no ber

To check your configurations using show commands, proceed to the “Checking the Configuration”

section on page 4-15; otherwise, proceed to the “Performing a Basic Serial Interface Configuration” section on page 4-14..

Performing a Basic Serial Interface Configuration

Note The Cisco 7200 VXR Port Adapter Jacket Card requires no configuration. Configure a port adapter in it

as you would any other port adapter.

Following are instructions for a basic configuration: enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration subcommands and the configuration options available for serial interfaces, refer to the appropriate software documentation.

In the following procedure, press the Retur

n key after each step unless otherwise noted. At any time you

can exit the privileged level and return to the user level by entering disable at the prompt as follows:

Router# disable

Router>

Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration

subcommands, as follows:

Router# configuration terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Step 2 Specify the first interface to configure by entering the interface serial subcommand, followed by the

interface address of the interface you plan to configure. See “Port Adapter Slot Locations” section on

page 1-4 and “Identifying Interface Addresses” section on page 1-6.

This example is for the serial interf

ace of T3 port 0 in port adapter slot 6 of a 7200 router.

Router(config)# interface serial 6/0 Router(config-if)#

Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using

the ip address subcommand, as in the following example:

Router(config-if)# ip address 10.0.0.0 10.255.255.255

Chapter 4 Configuring the Unchannelized Mode

Checking the Configuration

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the

interface characteristics.

Step 5 Re enable the interfaces using the no shutdown command. (See the “Replacing an Existing Port

Adapter” section on page 4-3.)

Step 6 Configure all additional port adapter interfaces as required. Step 7 After including all of the configuration subcommands to complete your configuration, press

Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Step 8 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config [OK] Router#

This completes the procedure for creating a basic configuration.

Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, and use the ping and loopback commands to check connectivity. This section includes the following subsections:

• Using show Commands to Verify the New Interface Status, page 4-15

• Using the ping Command to Verify Network Connectivity, page 4-20

• Using loopback Commands to Troubleshoot Network Problems, page 4-20

Using show Commands to Verify the New Interface Status

Table 4-3 demonstrates how you can use the show commands to verify that new interfaces are configured

and operating correctly and that the PA-MC-T3-EC appear

s in them correctly. Sample displays of the

output of selected show commands appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the “Related Documentation” section on

page iv.

Checking the Configuration

Using the show interfaces Command

The show interfaces serial command displays status information (including the physical slot and interface address) for the interfaces you specify.

For complete descriptions of inte

rface subcommands and the configuration options available for Cisco 7200 VXR router interfaces, refer to the publications listed in the “Related Documentation”

section on page iv.

Note The outputs that appear in this document may not match the output you receive when running these

commands. The outputs in this document are examples only.

Following is an example of the show interfaces serial command for Cisco 7200 VXR routers. In this example, the port adapter is in slot 5 of a Cisco 7200 VXR router:

Router# show interfaces serial 1/0/1:0 Serial 1/0/1:0 is up, line protocol is up Hardware is PA-MC-2T3E MTU 1500 bytes, BW 1536 Kbit, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation HDLC, crc 16, loopback not set Keepalive not set Last input 00:00:08, output 03:29:07, output hang never Last clearing of "show interface" counters 01:08:09 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: weighted fair Output queue: 0/1000/64/0 (size/max total/threshold/drops) Conversations 0/1/256 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) Available Bandwidth 1152 kilobits/sec 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 73 packets input, 22338 bytes, 0 no buffer Received 71 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 70 packets output, 19838 bytes, 0 underruns 0 output errors, 0 collisions, 1 interface resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions

Using the show controllers Command

You can display information for the T3 controller within a PA-MC-T3-EC in Cisco 7200 VXR routers with the show controllers t3 port-adapter/t3-port [brief | tabular] command where:

• brief displays a list of configurations only.

• tabular displays a list of configurations and MIB data in a tabular format.

Note If you use the show controllers t3 port-adapter/t3-port command without either of the optional

arguments (brief or tabular), all information is displayed for the T3 controller you specified; therefore, the resulting display output can be extensive.

Chapter 4 Configuring the Unchannelized Mode

Checking the Configuration

If you use the show controllers T3 command without specifying a port address (slot/port-adapter/port), all information is displayed for all T3 port adapters in the router; therefore, the resulting display output can be extensive.

Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the “Related

Documentation” section on page iv for detailed command descriptions and examples.

The ping co

mmand sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!)

indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a

bad connection.

Following is an example of a successful pi

ng command to a remote server with the address 10.0.0.10:

Router# ping 10.0.0.10 <Return> Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms Router#

If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.

Proceed to the next section, “U

sing loopback Commands to Troubleshoot Network Problems,” to finish

checking network connectivity.

Using loopback Commands to Troubleshoot Network Problems

If you have difficulty with the PA-MC-T3-EC configuration or installation, you can troubleshoot the port adapter using the loopback command. Refer to the “Configuring Loopback Mode for the Serial

Interface” section on page 4-9 for instructions on setting loopbacks.

If the ping command

to the remote IP address failed, then use loopbacks to troubleshoot the T3

connection using the following steps:

Step 1 Use the show controller T3 and show interfaces serial commands to confirm that the T3 controller,

serial interface, and line protocol are up.

Step 2 Place the serial interface of the PA-MC-T3-EC in local loopback using the loop local command. Step 3 Repeat the ping command using the IP address of the local serial interface. Using the previous example

where the remote server’s IP address was 10.0.0.10, if the local IP address is 10.0.0.5, then use the command:

ping 10.0.0.5

If the ping is successful, proceed to Step 4. A failure indicates a configuration problem or a hardware problem with the PA-MC-T3-EC.

Step 4 Remove the local loop with the no loopback command and place the remote server or DSU in network

loopback with the loopback remote command.

Chapter 4 Configuring the Unchannelized Mode

Checking the Configuration

Note The loopback remote command is only available when the framing is set to c-bit parity. If the framing

is not set to c-bit parity, the remote server will have to be placed into network loopback by someone at the remote site.

Step 5 Repeat Step 3. If the ping is successful, then the PA-MC-T3-EC and the T3 link to the remote site is

functioning correctly. The problem is probably in the remote DSU or server configuration or hardware. If

the ping fails, then a problem exists for: the T3 link to the remote site, the remote server , the DSU

configuration, or the hardware.

Restrictions for MLP to Be in the Hardware Accelerated Mode

If the restrictions in this section are met, the Multilink PPP (MLP) bundle operates in hardware mode by default.

• The maximum supported member link bandwidth is T1. If a clear channel interface is made part of

a Multilink bundle, the bundle will operate in software mode.

• All links in the bundle must be of equal bandwidth. Adding a link of unequal bandwidth causes the

Multilink bundle to go into software mode.

• All links must be from the same port adapter. Adding any additional link from another port adapter

causes the bundle to switch to software mode.

• A maximum of 12 links per bundle is supported. Adding any additional links to the bundle causes

the Multilink bundle to go into software mode.

• Configuring ppp multilink multiclass MLP causes the Multilink bundle to go into software mode.

• Fragment sizes supported in the hardware mode are 128, 256, and 512 bytes. If different

fragmentation sizes are configured, and if the bundle is in hardware mode, fragment size is adjusted to the nearest of the supported fragment sizes, and the hardware is programmed accordingly.

• The bundle will operate in software mode if MLPPP is configured using Virtual-Templates as described

in the following link.

http://cco/en/US/tech/tk713/tk507/technologies_configuration_example09186a00800a3e98.shtml

• If interleaving is enabled, the bundle is in hardware mode only if there is only one link in the bundle

and the fragment size configured (or selected) is 128 bytes and above. The bundle switches to software mode if any additional link is added or the fragment size that is configured or selected is less than 128 bytes.

• A maximum of 168 bundles per port adapter are supported in hardware mode. For calculating the

maximum number of bundles in hardware mode, MLP a nd Multilink Frame Relay bundles in hardware mode are included, and the MLP bundles that have interleaving enabled and are in hardware mode are excluded. Configuring any additional bundle makes the bundle operating in software mode.

• Fragmentation counters on the transmit (TX) side are not available because the hardware does not

support these counters.

MLPPP/MLFR Scale Recommendations

Table 5-1 list s the recommendations to consider when you use PA-MC-T3-EC/PA-MC-2T3-EC to

configure MLPPP/MLFR bundles on 7200 router:

Note The MLPPP/MFR bundles with links across different port adapters on the Cisco 7200 router are

supported for backward compatibility. Cisco recommends that the MLPPP/MLFR bundles using PA-MC-T3-EC/ PA-MC-2T3-EC are from the same port adapter.

Using the show frame-relay multilink Command to Determine if MLFR Is Hardware Accelerated

The show frame-relay multilink command provides information on whether or not the Multilink Frame Relay (FRF.16) bundle is in hardware mode.

Chapter 5 Configuring the Channelized Mode

PA-MC-T3-EC Hardware Accelerated Features and Restrictions

• Transmit (TX) fragmentation with hardware-enabled MLFR is not supported.

• A maximum of 168 bundles per port adapter is supported in hardware mode. For calculating the

maximum number of bundles in hardware mode, MLP and MLFR bundles in hardware mode are included, and the MLP bundles that have interleaving enabled and are in hardware mode are excluded. Configuring any additional bundle makes the bundle operate in software mode.

Using the show frame-relay fragment Command to Determine if Frame Relay Fragmentation Is Hardware Accelerated

The show frame-relay fragment command provides information on whether Frame Relay Fragmentation (FRF.12) on a data-link connection identifier (DLCI)

is enabled in hardware.

Router# show frame-relay fragment interface dlci frag-type size in-frag out-frag dropped-frag Se1/0/28:0.1 200 end-to-end 256 Hardware FRF12: No Counter Support Se1/0/28:0.2 201 VoFR-cisco 300 129 2662 0 MF1 214 VoFR-cisco 300 112 112 0

Restrictions for Frame Relay Fragmentation to Be in the Hardware Accelerated Mode

If the restrictions in this section are met, the Frame Relay Fragmentation (FRF.12) bundle operates in hardware mode by default.

• The hardware mode supports only three fragment sizes: 128, 256, and 512 bytes. If the user

configures a different fragment size, the fragment size is adjusted to the supported fragment size.

• If the vofr command is configured on a data-link connection identifier (DLCI), FRF.12 goes into

software mode, and is configured in software. Removing the vofr command again reconfigures the FRF.12 bundle to be in hardware mode.

• If the frame-relay fragmentation voice-adaptive command is configured on an interface, the

FRF.12 bundles on all DLCIs on that interface switch to software mode. Removing the command again reconfigures the FRF.12 bundle to be in hardware mode.

• FRF.12 for MFR interfaces are always in software mode.

• The frame-relay fragment <size> end-to-end command is not supported on a MFR interface

which is hardware enabled. An error message like below is generated by the router.

%MFR1 : is Hardware enabled. % Use map-class for configuring frf.12 on this interface.

• If PPP over Frame Relay (PPPoFR) or Multilink PPP over Frame Relay (MLPoFR) is configured

on any DLCI, all the DLCIs configured with the hardware FRF.12 on that interface switch to software mode.

• Removing the PPPoFR or MLPoFR configuration on the DLCI does not switch back the DLCIs to

operate in hardware mode. Moving to hardware mode can be done only after removing all PPPoFR or MLPoFR configuration on all DLCIs on the interface and reloading the router.

Using the EXEC Command Interpreter

The system prompt for the privileged level ends with a pound sign (#) ins

tead of an angle bracket (>).

At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a

privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, t

he system displays the privileged-level system prompt (#):

Router#

Replacing an Existing Port Adapter

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the “Using

the EXEC Command Interpreter” section on page 5-7 for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the

source of the configuration subcommands, as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Step 3 Shut down the T3 controller on the PA-MC-T3-EC with the shutdown controller command.

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with th

e no shutdown controller command.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# shutdow

Router(config)# controller T3 1/1 Router(config-controller)# shutdow

Note Both T3 ports of the PA-MC-T3-EC should be shut down before removing the port adapter.

Step 4 Verify that the two T3 ports are now shut down using the show controller T3 command.

The following example is for a PA-MC-T3-EC in port adapter slot 6 of a Cisco 7200 VXR router:

Router(config-controller)# end Router# s

how controller T3 6/0

T3 6/0 is administratively down.

Router# s

how controller T3 6/1

T3 6/1 is administratively down.

Step 5 Save the shutdown configuration to nonvolatile memory.

Router# copy running-config startup-config

Step 6 Replace the port adapter in the slot. See the “Replacing an Existing Port Adapter” section on page 5-7

for more information.

Step 7 Re-enable the port adapter by doing the following:

a. Repeat Step 3 to re-enable an interface, but substitute the no shutdown command for the shutdown

command.

b. Repeat Step 4 to verify that the interfaces are in the correct state and no longer shut down. Use the

show controller T3 command

c. Repeat Step 5 to write the new configuration to memory.

Use the copy running-conf

ig startup-config command.

For complete descriptions of software configuration commands, refer to the publications listed in the

“Related Documentation” section on page iv.

Configuring a Channelized T3 Link

After you verify that the new PA-MC-T3-EC is instal

led correctly (the ENABLED LED goes on), use

the privileged-level configure command to configure the new interface. Be prepared with the information you need, such as the following:

• Protocols you plan to route on each new interface

• IP addresses, if you plan to configure the interfaces for IP routing

The conf

igure command requires privileged-level access to the EXEC command interpreter, which

usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access.

• Configuring the T3 Controller to Enable Remote Loopback, page 5-13

• Shutting Down the T3 Controller, page 5-13

Selecting a T3 Controller

You must enter the following controller command, before any other configuration commands, to select the T3 controller you want to configure:

controller T3 c

hassis-slot/T3-port for Cisco 7200 series router

The example that follows is for a port

adapter in slot 1 of the Cisco 7200 VXR routers:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t3 1/0 Router(config-controller)#

Setting Channelized Mode for the T3 Controller

Note Channelized mode is the default, so you only need to configure the T3 controller for channelized mode

if it had previously been set to “no channelized” mode.

To configure the T3 for channelized mode, use the channelized command. The following example is for a PA-MC-T3-EC in port adapter slot 1 of a Cisco 7200 VXR router:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/0 Router (config)# channelized

Change to channelized mode will cause cbus complex reset. Proceed? [yes/no]:

When the PA-MC-T3-EC is configured for channelized T3 mode, its default MTU size is set to 1500 for compatibility with other T3 equipment and port adapters.

When the T3 controller is configured to be

channelized, 28 T1 lines are created. To configure the T1

lines, refer to the “Configuring T1 Lines” section on page 5-13.

Setting the Framing Type for the T3 Controller

At the prompt, specify the framing type using the framing [c-bit | m23 | auto-detect] controller command.

You can set c-bit framing format as follows:

Router(config-controller)# framing c-bit

You can set M23 framing format as follows:

Router(config-controller)# framing m23

You can request the PA-MC-T3-EC to detect the framing type it is receiving from the far end and transmit that same framing type as follows:

Router(config-controller)# framing auto-detect

Specifying the Cable Length for the T3 Controller

At the prompt, specify the cable length using the cablelength feet controller command where:

• feet is a numeral from 0 to 450.

• The default value is 49 feet.

An example follows:

Router(config-controller)# cablelength 40

Note For the cablelength feet command, user-specified T3 cable lengths are structured into ranges: 0–49 and

50–450 to represent short and long cables.

If the numerical value entered by the user falls within

the lower range, then the PA-MC-T3-EC T3 port is set for short cable output levels. If the value falls into higher range, the long cable output levels will be used.

In the preceding example, a cable len

Setting the Clock Source for the T3 Controller

At the prompt, set the internal or line clock source for the selected T3 controller with the clock source {internal | line} controller command where:

• line selects a network clock source.

• internal selects an internal clock source.

The default is cloc

k source internal.

Examples follow:

• Instruct the PA-MC-T3-EC to use a line clock source.

The example that follows is for a port adapte

Configuring MDL Messages for the T3 Controller

You can configure maintenance data link (MDL) messages (which are defined in the ANSI T1.107a-1990 specification) on the PA-MC-T3-EC.

Note MDL messages are only supported when the T3 framing is set for c-bit parity. (See the “Setting the

Framing Type for the T3 Controller” section on page 5-10.)

To configure MDL messages, use the m

dl {transmit {path | idle-signal | test-signal} | string {eic | lic

| fic | unit | pfi | port | generator} string

} controller commands where:

• eic is the equipment identification code (up to 10 characters).

• lic is the location identification code (up to 11 characters).

• fic is the frame identification code (up to 10 characters).

• unit is the unit identification code (up to 6 characters).

• pfi is the facility identification code to send in the MDL path message (up to 38 characters).

• port is the equipment port, which initiates the idle signal, to send in the MDL idle signal message

(up to 38 characters).

• generator is the generator number to send in the MDL test signal message (up to 38 characters).

Use the no fo

rm of this command to remove MDL messages. The default is that no MDL message is

configured.

Examples of MDL Message Configuration

Examples of configuring MDL messages follow:

• Enter controller configuration mode first.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/0 Router(config-controller)#

• Enable the MDL path message transmission as follows:

Router(config-controller)# mdl transmit path

• Enable the MDL idle signal message transmission as follows:

Router(config-controller)# mdl transmit idle-signal

• Enable the MDL test signal message transmission as follows:

Router(config-controller)# mdl transmit test-signal

Configuring Loopback Mode for the T3 Controller

With loopbacks, you can detect and isolate equipment malfunctions by testing the connection between thePA-MC-T3-EC interface and a remote T3 device such as a DS3 MUX. Remote loopback sends a command to loop the T3 line at the far end (central office). It can be used to diagnose problems with cables from the port adapter to the switching office. Network loopback loops the PA-MC-T3-EC port back to the network, allowing the remote end to test the connection to the PA-MC-T3-EC.

Local loopback loops the PA-MC-T3-EC port back to

itself, allowing it to be tested in isolation from the

T3 cables and remote T3 equipment.

The l

oopback subcommand places an interface in loopback mode, which enables test packets that are

You can configure the T3 controller for loopback modes using the loopback {l

ocal | network line|

remote} controller command.

The default is no loopback.

To return the T3 controller to its default unlooped condition, use the no for

m of the command.

Table 5-2

Note T3 remote loopbacks are only available when you use c-bit parity framing.

Shutting Down the T3 Controller

You can shut down the T3 controller on the PA-MC-T3-EC with the shutdown controller command.

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with th

e no shutdown controller command.

The example that follows is for a port ad

apter in slot 1 of a Cisco 7200 VXR router (with an NPE-G1 or

NPE-G2):

Router(config)# controller t3 1/0 Router(config-controller)# shutdow

Note For consistency throughout the following configuration examples and whenever possible, the port

addresses 1/0 and 1/0/1:1 are used for Cisco 7200 VXR routers.

Your PA-MC-T3-EC port addressing might be different depending on the Cisco 7200 VXR router chassis slot in which your PA-MC-T3-EC is installed.

Creating a Logical Channel Group on a T1 Line

You can create a logical channel group on a T1 line using the t1 t1-line-number channel-group channel-group-number timeslots list-of-timeslots

[speed {56 | 64}] controller command where:

• t1-line-number is 1 to 28.

• channel-group defines a logical channel group.

• channel-group-number is 0 to 23.

• timeslots list-of-timeslots can be 1 to 24 or a combination of subranges within 1 to 24 (each

subrange is a list of time slots of the T1 line).

• speed{56 | 64} is an optional argument that specifies the speed of a time slot to be either 56 kbps or

64 kbps.

The following example configures logical channel group

20 on T1 line 1 and assigns channelized time

slots 1 to 5 and 20 to 23.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# t1 1 ch

annel-group 20 timeslots 1-5, 20-23

Note Each T1 link may have up to 24 channel groups with an overall limit of 128 for the 28 T1 links on each

T3 port. Unused channel groups in one T3 port may not be used by the other T3 port.

Note Each channel group defined with this command causes a serial interface to be created. Refer to the

“Performing a Basic Serial Interface Conf

iguration” section on page 5-24 for instructions on configuring

these interfaces.

Note All the encapsulation formats, such as PPP, HDLC, SMDS, Frame Relay, and switching types are

applicable to the serial interface and can be set using the serial interface configuration commands.

Removing a Logical Channel Group from a T1 Line

You can remove a logical channel group from a T1 line with the no t1 t1-line-number channel-group channel-group-number controller command where:

• t1-line-number is 1 to 28.

• channel-group-number is 0 to 23.

The following example removes logical channel group 10 from channelized T1 line 1.

The example is for a port adapter in slot 1 of a Cisco 7200 VXR router.

Router(config)# controller T3 1/0 Router(config-controller)# no t1 1

channel-group 10

Note If logical channel groups have previously been configured on a port, and you switch to no channelized

mode, first remove all channel groups before invoking the no channelized command.

Setting the Framing Format on a T1 Line

You can specify the T1 framing format using the t1 t1-line-number framing {esf | sf} controller command where:

• t1-line-number is 1 to 28.

• The default framing format is Extended Supe frame (ESF).

The examples that follows are for a po

rt adapter in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# t1 6 fr

aming sf

Other options for setting Super Frame (SF) include:

Router(config-controller)# t1 6 framing ? esf Extended Superframe Framing format sf Superframe Framing Format

Router(config-controller)# t1 6 fr

aming sf ?

hdlc-idle Specify the HDLC idle pattern on a T1 <cr>

Router(config-controller)# t1 6 fr

aming sf hdlc-idle ?

0x7E Use 0x7E as HDLC idle pattern 0xFF Use 0xFF as HDLC idle pattern

Router(config-controller)# t1 6 fr

aming sf hdlc-idle 0x7e ?

The following example sets ESF framing format for T1 line 16.

Router(config)# controller T3 1/0 Router(config-controller)# t1 16 f

raming esf

Note Use of the 0xFF HDLC idle pattern may help prevent false yellow alarms in the remote T1 device when

SF framing is used.

Setting the Yellow Alarm Configuration for a T1 Line

You can use the [no] t1 t1-line-number yellow {detection | generation} command (where t1-line-number is 1 to 28) to turn the detection or generation of a yellow alarm on and off. When you

select SF framing, you should consider using the no t1-line-number yellow detection command to turn off yellow alarm detection, because the yellow alarm can be incorrectly detected with SF framing.

Setting the Clock Source on a T1 Line

You can set the internal or line (network) clock source for a T1 line with the t1 t1-line-number clock source {internal | line} controller command where:

• t1-line-number is 1 to 28.

• internal selects an internal clock source.

• line selects a network clock source.

The default clock source is internal.

Examples follow:

• Instruct T1 line 1 to use an internal clock source.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router.

Router(config)# controller T3 1/0 Router(config-controller)# t1 1 cl

ock source internal

• Instruct T1 line 16 to use a line clock source received from the network.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router.

Router(config)# controller T3 1/0 Router(config-controller)# t1 16 c

lock source line

Note Normally the T1 link should be configured to use the line clock recovered from the network. In cases

where the network does not provide the clock, such as two PA-MC-T3-EC port adapters connected back-to-back, one end of the T1 link must be set to internal clock and the other end to line clock.

Setting the FDL Configuration for a T1 Line

To enable and disable one-second transmissions of performance reports through the facility data link (FDL) (per ANSI T1.403 specification), you must use the t1 t1-line-number fdl ansi command where: t1-line-number is 1 to 28 on both ends of the connection.

Note You can use this command only when the T1 framing is ESF.

Use the no fo

rm of the command to disable remote performance reports.

Setting Loopbacks on a T1 Line

If you have difficulty with the PA-MC-T3-EC configuration or installation, you can troubleshoot the port adapter using the loopback command. Specify loopback for a T1 line using the following t1 t1-line-number loopback [local | network | remote]command where: t1-line-number is 1 to 28.

Configuring a BER Test on a T1 Line

Bit error rate test (BERT) circuitry is built into the PA-MC-T3-EC. With BER tests, you can test cables and signal problems in the field. You can configure BER tests on each of the 28 T1 lines, but only one BER test can be active at a time.

There are two categories of test patterns that can be generated

by the onboard BER test circuitry: pseudorandom and repetitive. The former test patterns are polynomial-based numbers and conform to the CCITT/ITU O.151 and O.153 specifications; the latter test patterns are zeros or ones, or alternating zeros and ones.

A list of the available test patterns follows:

• Pseudorandom test patterns:

–

• Repetitive test patterns:

–

All zeros (0s)

–

All ones (1s)

–

Alternating zeros (0s) and ones (1s)

Both the total number of error bits received and the total number of bits received are available for analy

sis. You can set the testing period from 1 minute to 14,400 minutes (240 hours), and you can also

retrieve the error statistics anytime during the BER test.

Note BER testing for the T3 link is not supported in channelized T3 mode. It is only supported for

unchannelized T3 ports.

When running a BER test, your system expects to receive the same pattern that it is transmitting. To accomplish this, two common options are available:

• Use a loopback somewhere in the link or network.

• Configure remote testing equipment to transmit the same BER test pattern at the same time.

Sending a BER Test Pattern on a T1 Line

You can send a BERT pattern on a T1 line with the t1 t1-line-number bert pattern pattern interval time [unframed]controller command. where:

• t1-line-number is 1 to 28.

• time is 1 to 14400 minutes.

• pattern is one of the following:

–

0s, repetitive test pattern of all zeros (as 00000...)

–

1s, repetitive test pattern of all ones (as 11111...)

–

2^11, pseudorandom test pattern (2,048 bits long)

2^15, pseudorandom O.151 test pattern (32,768 bits long)

–

2^20-O153, pseudorandom O.153 test pattern (1,048,575 bits long)

–

2^20-QRSS, pseudorandom O.151 QRSS test pattern (1,048,575 bits long)

–

2^23, pseudorandom O.151 test pattern (8,388,607 bits long)

–

alt-0-1, repetitive alternating test pattern of zeros (0s) and ones (1s) as (01010101)

The unframed option causes the BERT pattern to use th

e entire T1 bandwidth including the T1 framing

as well as payload bits. If unframed is omitted, then the T1 linewill be either SF or ESF framed as configured by the T1 framing command and the BERT pattern will occupy only the T1 payload bits.

Examples follow:

• Send a BERT pseudorandom pattern of 2^23 through T1 line 10 for 5 minutes.

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# t1 10 b

ert pattern 2^23 interval 5 unframed

• Send a repetitive pattern of all ones through T1 line 10 for 14400 minutes (240 hours).

The example that follows is for a port adapte

r in slot 1 of a Cisco 7200 VXR router:

Router(config)# controller T3 1/0 Router(config-controller)# t1 10 b

ert pattern 1s interval 14400 unframed

Note You can terminate a BER test during the specified test period with the no t1 bert command.

Viewing the Results of a BER Test

You can view the results of a BER test using the show controllers T3 chassis-slot/t3-port/t1-line-number controller command where: t1-line-number is 1 to 28.

You can view the results of a BER test at the following times:

• After you terminate the test using the no t1 bert command

• After the test runs completely

• Anytime during the test (in real time)

The example that follows is for a port adapte

Chapter 5 Configuring the Channelized Mode

Performing a Basic Serial Interface Configuration

Note The Cisco 7200 VXR Port Adapter Jacket Card requires no configuration. Configure a port adapter in it

as you would any other port adapter.

In the following procedure, press the Retur

n key after each step unless otherwise noted. At any time you

can exit the privileged level and return to the user level by entering disable at the prompt as follows:

Router# disable

Router>

Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration

subcommands, as follows:

Router# configuration terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Step 2 Specify the first interface to configure by entering the interface serial subcommand, followed by the

interface address of the interface you plan to configure. Tab le 5-3 provides an example.

Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using

the ip address subcommand, as in the following example:

Router(config-if)# ip address 10.0.0.0 10.255.255.255

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the

interface characteristics.

Step 5 Re-enable the interfaces using the no shutdown command. (See the “Replacing an Existing Port

Adapter” section on page 5-7.)

Step 6 Configure all additional port adapter interfaces as required. Step 7 After including all of the configuration subcommands to complete your configuration, press

Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Using the show controllers Command

You can display information for all T1 lines within a PA-MC-T3-EC with the show controllers T3 slot/port-adapter/port [brief | tabular | remote performance] command where:

• brief displays a list of configurations only.

• tabular displays a list of configurations and MIB data in a tabular format.

• remote performance displays a list of performance data from the remote end of a T1 connection.

Note If you use the show controllers T3 slot/port-adapter/port command without one of the three optional

arguments (brief, tabular, or remote performance), all information is displayed for the T3 controller you specified; therefore, the resulting display output can be extensive.

You can also display brief configuration information or tabular configuration and MIB information about a specific T1 line within a PA-MC-T3-EC with theshow controllers T3 slot/port-adapter/t3-port/t1-line-number [brief | tabular | remote performance] command where:

• t1-line-number is 1 to 28.

• brief displays a list of configurations only.

• tabular displays a list of configurations and MIB data in a tabular format.

• remote performance displays performance data from the remote T1 equipment.

Note The PA-MC-T3-EC does not support slip buffers and always reports local controlled slip seconds (CSS)

as 0.

Note To enable and display remote performance reports, see the “Setting the FDL Configuration for a T1

Line” section on page 5-16, and the “Using the show controllers T3 remote performance Command” section on page 5-33.

Using the show controllers T3 remote performance Command

Use the show controllers T3 chassis-slot/t3-port remote performance command to display performance data from the remote T1 equipment.

Checking the Configuration

Note If you do not first enable remote performance data with the t1 t1-line-number fdl ansi command, the

following message is displayed:

T1 1 - Remote Performance Data (Not available)

Note Although the PA-MC-T3-EC does not support local controlled slip seconds (CSS), remote T1 equipment

may report CSS values in the remote performance reports.

Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the “Related

Documentation” section on page iv for detailed command descriptions and examples.

The ping co

indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a

bad connection.

Following is an example of a successful pi

ng command to a remote server with the address 10.0.0.10:

If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.

Using loopback Commands to Troubleshoot Network Problems

If you have difficulty with the PA-MC-T3-EC configuration or installation, you can troubleshoot the port adapter using the loopback command. Refer to the “Configuring Loopback Mode for the T3 Controller”

section on page 5-12 for instructions on setting loopbacks.

If the ping command

to the remote IP address failed, then use loopbacks to troubleshoot the T3

connection using the following steps:

Step 1 Use the show controller T3 and show interfaces serial commands to confirm that the T3 controller,

serial interface, and line protocol are up.

Step 2 Place the serial interface of the PA-MC-T3-EC in local loopback using the loop local command.

Chapter 5 Configuring the Channelized Mode

Checking the Configuration

Step 3 Repeat the ping command using the IP address of the local serial interface. Using the previous example

where the remote server’s IP address was 10.0.0.10, if the local IP address is 10.0.0.5, then use the command:

ping 10.0.0.5

If the ping is successful, proceed to Step 4. A failure indicates a configuration problem or a hardware problem with the PA-MC-T3-EC.

Step 4 Remove the local loop with the no loopback command and place the remote server or DSU in network

loopback with the loopback remote command.

Note The loopback remote command is only available when the framing is set to c-bit parity. If the framing

is not set to c-bit parity, the remote server will have to be placed into network loopback by someone at the remote site.

Step 5 Repeat Step 3. If the ping is successful, then the PA-MC-T3-EC and the T3 link to the remote site is

functioning correctly. The problem is probably in the remote DSU or server configuration or hardware. If

the ping fails, then a problem exists for: the T3 link to the remote site, the remote server , the DSU

configuration, or the hardware.
