Hotwire DSL System Description

What is th e Hotwire DSL Sys tem?

The Hotwire® Digital Subscriber Line (DSL) system is a set of central site products that terminate and consolidate packet data traffic from many customers in a serving area. The DSL card(s) then forwards the traffic to one or more network access provider networks.

High-speed Internet and intranet access is either bridged or routed on the DSL line cards and multiplexed over backbone networks. By enabling very high speeds using DSL technology and concentrating Internet Protocol (IP) traffic, greater performance is realized.

In addition, the Hotwire GranDSLAM, with an endpoint such as a Hotwire 6310 ReachDSL version 1 (formerly MVL Termination Unit (RTU), can co-exist with plain old telephone service (POTS) over the same copper telephone line, providing simultaneous usage of POTS and digital applications. That is, the optional central office (CO) POTS splitter and customer premises POTS filter allow simultaneous voice and data connections over a standard telephone line.

The Shelf Concentration Module (SCM) card aggregates DSL traffic for the Hotwire 8620 and 8820 GranDSLAM chassis. The operation and configuration of this card is not within the scope of this document. See the

Concentration Module (SCM) Card User’s Guide

for more information.

DSL cards can reside in four types of chassis:

Hotwire Shelf

8600/8610 DSLAM



A 3-slot chassis with Ethernet uplink. The stackable design provides for up to six chassis to share management access through a single MCC card, which in turn allows an additional slot for a DSL card in each of up to five additional chassis. The 8610 DSLAM chassis offers the same benefits as the 8600 chassis, with the added capability of accepting high-density DSL cards (5 –24 ports) such as the 8343 SDSL card. Management access is through the Management Communications Processor (MCP) card. For more information, see either the

. The Operator has read-only access and can view configuration

NOTE:

There must be at least one Administrator configured in order to have system security.

Hotwire Management

NOTE:

The User Login screen only appears if one or more users have been defined on the MCC.

At the User Login screen, enter your login ID and password. You must wait until your login is verified, anywhere from two seconds to 12 minutes. If you have RADIUS Authentication, this verification takes some time while each RADIUS server is contacted one at a time.

If you are denied access during a Telnet session, the session stops and an error is logged. If you are using a console, return to the User Login screen.

NOTE:

If you forget your password, contact your Technical Support Center. Have the serial number of the MCC card available, and the service representative will provide you with a password.

Configuring Subnet Addressing

To define a subnet entr y, the IP address has to be entered as the lower boundary address of the subnet. Otherwise, only a host entry can be configured. For example, a subnet with a mask of 255.255.255.192 requires one of the following IP addresses, where

= any IP address:

xxx



xxx.xxx.xxx



xxx.xxx.xxx



xxx.xxx.xxx



xxx.xxx.xxx

Configuring Subnet Masks

After the IP address is entered, a default subnet mask is displayed. The default subnet mask is based on the IP address entered and can be changed.

If the IP Address entered is . . . Then the Default Subnet Mask is . . .

xxx.xxx.xxx. xxx.xxx.

0.0.0 255.0.0.0

xxx. xxx.xxx.xxx.xxx

To configure the DSL card, a valid subnet must be used. When a Host entry is input, any valid IP address results in a subnet mask of 255.255.255.255.

.0 .64 .128 .192

0 255.255.255.0

0.0 255.255.0.0

Domain Types

Service Domain

Management Domain

3. DSL Card Configuration

To monitor and control the overall system, the Hotwire Access Network should be partitioned into two distinct domains:

Service domain(s) (Layer 2, MAC Bridging)



Management domain (Layer 3, IP Routing)



A service (or data) domain is comprised of all clients and servers (grouped physically or virtually) that communicate across a common WAN or LAN connection for Internet or intranet access. This is the Layer 2 bridging domain of the NSP. The Access Node cards and the Service Nodes are the Hotwire components of this domain. The service dom ain also encom pas ses an NSP and all end-user systems that subscribe to that NSP.

The primary function of the management domain is monitoring and configuring the DSL cards and service domains served by the DSLAM. The management domain should reside in a mutually exclusive domain from that of the service (data) domain(s). The MCC card functions as a service router and is the primar y tool for configuring and diagnosing the manage men t domain.

It is recommended that the management domain reside in a separate domain from the service domain(s) for security purposes and to improve download performance.

Minimum Configuration

The minimum configuration of the DSL port card differs, depending on the type of SN used.

Minimum Configuration When Using the 5620, 6310, or 6350 SN

When using either the 5620, 6310, or 6350 SN, the DSL port card is in control of the connection. At a minimum, you must configure the following:

VNIDs on a DSL card (see



The active VNID and the Next Hop Router on each DSL port/interface (see

performing a reset, or has never been made active), or Port Not Selected (a port number has not been specified for display) (Default = Por t Not Selected).

SN Type – Model number of the service node (Default = 6301R2). For Model 830 3/8304 IDSL cards, SN type is Paradyne 6301R2, Paradyne 6302R2, or None (R2 indi cates Release 2 or great er).

Line Code – 2B1Q. (This field is read- only.) Data Rate – 144/128/64 (Default = 144 Kbps). Link Encapsulation – Determines the protocol to be run on the select ed port

(Default = EtherHDLC). Use Ctrl-v for a pop-up menu with available selec ti ons. Choose from the following:

– EtherHDLC for IP packet applications – FUNI/MPOA for 8304 cards only

NOTE: If you select FUNI/MPOA, the endpoint must be configured for routing only, otherwise the line will fail to come up and a SYSLOG message will be generated.

Channel for 64 Kbps – B1/B2 (Default = B1). Vali d channel for 64 Kbps operati on. T ransceiver Mode – Enter NT (Network Termination) or LT (Line Termination)

(Default = LT). NT is used for timing while LT is used for data. One and only one IDSL port in each chassis must be dedicated as NT and connected to the appropriate ISDN timing source in the CO. This timing is then distributed to all other IDSL ports in the chassis. Only the first four ports on the card can be set to NT.

– For timing: An IDSL circuit must be synchronized with the Digi tal Carrier System

(the Digital Loop Carrier or DLC). The port you select for NT mode will be used to terminate a connection to an LT dedicated for system clock use. This NT port will probably not be used for data, but will derive the 2.048 Mhz system clock from the connection and distribute this timing to the other 23 IDSL ports on this card, and to other IDSL port cards via the backplane cl ock circuit. Once you have set one of the ports on the IDSL card for NT mode, use the IDSL Clock Configuration screen (A-G-B) on the MCP card to configure on e of the clock circuits on the backplane to receive its timing from the IDSL port you just configured. To do this, set the Clock Configuration for NET_CLOCK1/NET_CLOCK2 fiel d to 3 for Drive System Clock).

NOTE: If the NT port loses the connection and the timing source f ails, all IDSL loops on the chassis may lose data (denoted by Major Alarm and SNMP trap). For redundancy, you may wish to dedicate an addi tional port on another IDSL card in the chassis as a spare tim ing source and leav e the port it in LT mode. In case of failur e, this secondary timing port can be enabled r em otely by changing the status of the primary timing port to LT and the secondary port to NT. Be aware that the NET_CLOCK1 and NET_CLOCK2 options must be configured correctly on the MCC card. See the

3. DSL Card Configuration

Configuring VNID(s) on a DSL Card

A VNID is a Virtual Network Identifier known as the 802.1Q tag between port cards with an Ethernet network interface and the Interworking Packet Concentrator (IPC). This directs traffic between the ISP and the end user. Tagging occurs between the DSL card and the IPC to ensure that data is sent to the correct location. This helps to ensure that data is not broadcast to all ports when Mux forwarding is enabled. To enable VNID tagging for port cards with an Ethernet network interface, you must first ensure that matching groups are configured on the IPC.

VNID configuration is required on DSL port cards when the port card is



operating in the VNET-Bridged mode. However, when a DSL port card with an ATM Network interface is operating in Standard mode, no VNID configuration is required.

802.1Q VLANs must be configured on the IPC when a DSL port card with an



Ethernet Network interface is used. Howev er, 802.1Q VLANs are not required when a DSL port card with an ATM Networ k interface is used in conjunction with an SCM card in the Hotwire 8820 GranDSLAM.

Before configuring VNIDs, you must enable VNID tagging (

), then reset the

A-E-A

card.

NOTE:

Before configuring VNIDs, determine what type of endpoints are attached. Desired DSL port card configuration settings may differ, depending on the SN attached.

This section presents an example of an exception when IP Scoping must be disabled when using a DSL Router. IP Scoping on the port card must be disabled if the DHCP relay capability on the DSL Router is enabled, and the IP addressing scheme allows the core device at the access provider’s lo cation to ARP d i re ctl y for the client behind the DSL Router. In the figure below, the Cisco Router ARPs directly for the client PC. Therefore, IP Scoping must be disabled on the port card for proper data communication.

Table 3-4. Bridge Options (1 of 4)

General (G e n eral Bridge Paramete rs) A-E-A

Gives the user the ability to configure general b rid ge parameters. You must reset the card for your changes to take effect.

Complete Entry Timeout – Enter the bridge aging timeout (10–1,000,000 seconds) (Default = 300). This option determines how long the system waits before posting an ARP entry as timed out.

Complete Entry Cleanup Interval – Enter the bridge aging cleanup interval in seconds. This is typically set t o 1/2 of the Complete Entry Timeout setting. (Default = 150). This option determines how often the system removes ti me d-out entries from the ARP cache.

MAC Learning in Auto VNID Mode – For DSL cards with an ATM network interf ace only. Enable/Disab le (Default = Disable). Enables th e bridge to lea rn the MAC addresses of clients (useful for troubleshooting but reduces packet throughput on bridge). If you change this setting, you must reset the card before the change will take effect.

VNID Tagging – For DSL cards with an Ethernet network interface only. Enable/Disable VNID tagging on the card (Default = Disable). Whe n you enable tagging, you are assuming that the oth er end of the connection supports 802.1Q taggin g.

Card VNID Table A-E-B

Gives the user the abil ity to configure Virtual Network IDs (VNIDs) for the entire card. There are a maximum of 16 entries per 4- and 12-port cards, or 32 entries per 24-port card. If VNID Tagging is disabled (see

General (General Bridge Parameters) A- E-A

page 3-24), only one VNID appears on this screen to be configured.

NOTE: Enabled fields display En. Disabled fields display blank.

Item – Enter 0 (zero) to add a new record. Or, enter 1–16 (for 4- and 12-port cards) or 1–32 (for 24-port cards) to display configured information for that item number.

VNID – Enter a VNID between 2–4000 for DSL cards with an Ethernet network interface, or 2–255 for DSL cards with an ATM network interface (Default = NULL). A space del etes the current VNID entry and the rest of the values in this row. Do not enter a space if a message is displayed indicating that any port has this as the active VNID.

Mux Fwd – Enabl e/blank (disabl e) (Default = Enable ).

When Mux Fwd is enabled, all upstream traffic is sent out through the 10BaseT



interface on port cards with an Ethernet network interface or through the SAR interface on port cards with an ATM network interface. Forwarding restrictions are set by the other param eters on the screen.

When Mux Fwd is disabled, the DSL card forwards tr affic based on a destination

MAC address.

Either enabled or disabled, traffic is forwarded on ports ha ving the same VNID designation.

IP Filter – Enable/blank (disable) (Default = Disable).

When IP filtering is enab led, the DSL card looks at IP traffic from the subscriber to



authenticate the source IP address. When IP filtering is disabled, no source authentication check is performed.

prompt:

IP Filter (IP Filter Configuration screen) (A-G-A)

Allows you to build multiple rules for an IP filter. A filter consists of a set of rules applied to a specific interface to indicate whether a packet received or sent out of that interface is forwarded or discarded. You can add, edit, or delete fi lter rules within a named set.

A filter works by succe ssively applying the rules to the information obt ained from the packet header until a match is found. The filter then performs the action specified by the rule on that packet, which forwards or discards the packet. If all the rules are searched and no match is found, the configured default filter action is executed.

Host rules have higher precedence than network rules. Rules apply to the source/destination IP address, source/destination port number, and traffic types, such as TCP/UDP/ICMP. TCP/UDP/ICMP traffic is forwarded to discarded based on the conditions specified in the rule, including source and/or destination address and source and/or destination port number. You can have up to 33 rules per fi lter. Each rule red uces the packet th roughput of the DSL card.

There can be 24 filters per DSL card wit h a max imum of two filters per DSL port, one inbound filter and one out bound filter. The same filter can be applied as an inbound filter and an outbound filter. Filte rs are configured on the port card and the process ing takes place on the endpoint.

NOTE: Once your rules have been configured, you can then bind and activ ate the filter on the DSL interface using the

Selftest D-A

Displays the results of the last disruptive selftest of th e DSL card. This selftest is only performed on p ow er up of the sy stem or a rese t of the car d. Ea ch subsyst em ( proc esso rs, memory, and interfaces) reports pass or fail. I f al l subsystems pass, the card has passed selftest. If a subs ystem fails, reset or replace the card.

You can determine when the selftest occurr ed by reading the elapsed time si nce the last reset on the card.

Alarms (Card Alarms) D-B

Displays al l active card alarm conditions. Major alarms include Selftest Failure, Sanity Timer, No n-Supported Chassis, DSL or

Ethernet Port Fail ures , and Loss of Netw ork Timing (f or ports designat ed as NT). Refer to

Table 5-2, Major Alarms.

Minor alarms include Config Error (configuration has been corrupted), Threshold Exceeded for DSL Margi n or Li nk Down events, and Wrong SN Ports. Refer to

Table 5-3, Mino r Alarms.

DSL Packet Echo Test D-C

Allows you t o conduct a nondisruptive packet test bet ween the DSL card and Hotwire SN endpoint. Test packets are sent to the SN at 10 percent of the line rate and echoed back to this card, where they are counted and checked for errors. The running time of the test can be specified and the test will continue until the specified time has elapsed or the t est is stopped. Only one port can be tested at a time .

Results include packets sent, valid packets received, errored packets received, errored seconds, and elapsed time of the test.

NOTE: Errored pac ket s and error ed seco nds ma y resul t if one SN has heavy Ethernet traffic, or two or more SNs have moderate to heavy Ethernet traffic (such as in a multidrop environment).

SN Selftest D-D

Allows you to perform a power-on Service Node selftest. A port number can be selected to perform the test.

NOTE: Entering y es in the Reset SN field will temporarily disrupt the dat a path on the specified DSL port while the SN resets.

BERT (Bit Error Rate Test) D-E

Allows you to perform a Bit Error Rate Test (BERT). A port number can be selected to perform the test. You can choose to run the test for 10 seconds or two minutes. The test will run for the full ti me selected. This test is not supported for MVL, IDSL or ReachDSL port cards.

NOTE: If you choose not to wait while the test runs for its selected time, you can exit this screen, then reenter it to view the current status of the test.

BERT (Block Error Rate Test) D-E

Allows you to perform a Block Error Rate Test (BERT). This test is supported for MVL cards with version 3.1 or greater software and ReachDSL cards.

Interface Name – Enter port number:interface number. The interfa ce number (1–4) represents each of the possible Service Nodes that may be attached to the sel ected port. The link to the Service Node must be active to run the BERT since packets are exchanged between the Access Node and the Service Node.

Serial Number – The serial number of the Service Node appears in this field when you enter an Interface Name.

Duration – (1–65535). Enter the number of packets that will be exchanged in both the upstream (Service Node to Access Node) and downstream (Access Node to Service Node) directions. If you enter a number from 1 through 65534, this is an iterative test. If you enter 65535, th is is a continuous test.

Test Type – Displays one of the following:

Iterative – You entered a number from 1 through 65534 in the Durat ion field. The



test stops after the t ransfer of the specified number of packets. Continuous – You entered 65535 in the Duration field. The test runs until you select



Stop Test.

Start Test – Type y to start the test. You may display the res ults of the test ju st started, or you may start a BERT on anoth er interface by typing Ctrl-z, then reentering this screen and selecting another interface to test.

Stop Test – Type y to stop the test. Test Status – Displays Test Starting (Access Node is communicating the test request to

the Service Node), Test Running (Access Node and Service Node are exchanging test packets), or T est Complete.

Next TX Sequence Number – The number of the next test packet to be sent from the Access Node to the Service Node. Begins with the number entered in the Duration field and counts down to 0.

Next RX Sequence Number – The number of the next test packet expected to be received by the Access Node from the Service Node. Begins with the number entered in the Duration fiel d and counts down to 0.

Results – Displays the following:

Number of Good/Bad Blocks Received for Upstream and Downstream – Only

Troubleshooting

The status of each card in the Hotwire chassis is indicated on the Card Selection screen (see

Screens

Checking Alarms

If the Card Selection screen indicates that a Major or Minor Alarm is on a card, follow the menu selection sequence cause of the alarm.

No Response at Startup

DSL cards do not respond at startup after rebooting chassis. Reset the MCC card. Be sure LEDs go through the reset sequence twice within about one minute.

If a DSL card does not appear on the Card Selection screen because the MCC card can no longer communicate with it, the MCC card will generate a major alarm. Follow the MCC’s menu selection sequence (

Alarm Action

Ethernet Port Failure

1. Check cable connections to the chassis.

– If cables are terminated properly, go to Step 2. – If cables are not terminated properly, terminate them correctly.

2. Check cable connections to the hub or Ethernet sw itch.

– If cables are terminated properly, go to Step 3. – If cables are not terminated properly, terminate them correctly.

3. Check the Activity/Status LED at the Ethernet hub

– If Activity/Status LED does not indicate a problem, go to Step 4. – If Activity/Status LED indicates a problem, take appropriate

action.

4. Disconnect the Ethernet cable and replace it with a working cable from a spare port on the hub.

– If the replacemen t cabl e works , the origi nal is ba d and shou ld be

permanently replaced.

– If the replacement cable does not work, reconnect the original

cable and go to Step 5.

5. Move the DSL card and cable to another (spare) slot. – If this solves the problem, the connector or interfac e panel

connections f or the original slot are bad. Schedule maintenance for the chassi s and try to use the spare slot temporaril y.

– If this does not solv e the problem, the DSL card is prob ably bad

and should be replaced.

Link Down Threshold

(A trap message is sent if the number of DSL link down ev ents in 15 minutes exceeds th e selected value.)

If the threshold is set lo w (1–4) and the link is currently down, then



there may be a local loop or Service Node problem. Check bot h. – Verify that the Service Node is powered up, is connected to the

local loop , and has passed its selftest .

– Check the loop for continuity. If the threshold is set lo w (1–4) and the link is currently up, then an



event had occurred to temporarily knock out the connection. Log the event and continue normal operation.

If the threshold is set high (more than 4) and the link is currently



down, then chec k the Ma rgin s tatist ics o v er the past hour an d da y. If the numbers are low, there may be a situation where the DSL modems cannot train. This condition may be temporary or permanent. However, if it persists, the l oop m ay have to be reengineered for better performance by performing one of the following:

– Remove bridge taps. – Change cable gaug e on a cable section. – Run new c able. – Remove other noise-generating digital circuits from the cable

bundle.

If the threshold is set high (mor e than 4) and the lin k is curren tly up ,



then there may be a loose connection in the loop plant, or the loop is barely usable. Check the Margin. If the Margin is normal, there may be a loose connection. If the Margin is low, try reducing the speed of the DSL port.
