THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: 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-frequencyenergy 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.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequencyenergy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by 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.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Chapter 1 Introducing the MGX 8230

MGX 8230 System Overview

The Applications of the MGX 8230

The MGX 8230 operates in the following applications:

Note Refer to the Cisco documentMGX 8230 Edge Concentrator Overview for additional information on the applications of the MGX 8230.

Note See Chapter 5, “Configuring the MGX 8230 Shelf” for information on configuring MGX8230 applications.

As a feeder

The MGX 8230 concentrates narrow-bandandmedium-bandATM, Frame Relay, and into a single,wide-bandATM feeder trunk that connects to a BPX8600-seriesswitch or a MGX 8850 switch.

As a Stand-AloneSwitch

The MGX 8230 can be deployed as a stand-aloneswitch, providing“cross-connect”connections between UNI and NNI ports. Traditionally, this would be used in aconcentration-typemode, allowingstandards-basedadaptation and concentration of multiservice traffic onto one or morehigh-speedATM interfaces. This enables the MGX 8230 to interface to a multivendor ATM network, or to any other ATM attached device (such as a Cisco 7200 or GSR router LS1010, MSR 8450, and so on).

The MGX 8230 interfaces to the ATM equipment using a standard ATM UNI or NNI..

Multiprotocol Label Switching (MPLS)

As a component of the BPX 8680-IPuniversal service node, the MGX 8230 is capable of forwarding traffic into the BPX MPLS network by acting as a multiservice feeder

Consolidation of Cisco CPE Traffic

At the edge of the network, the MGX 8230 can interwork with and consolidate a wide variety of CPE equipment.

Multiservice Stand-aloneConcentrator

The MGX 8230 can be deployed as a stand-aloneconcentrator, interfacing to a multivendor ATM(non-BPX)network, as shown Figure1-5.The MGX 8230 interfaces to ATM equipment using a standard ATM UNI or NNI.

Universal Edge Architecture

The MGX 8230 supports a wide range of services over narrowband and mid-banduser interfaces by mapping all service traffic to and from ATM using standardized interworking methods. The MGX 8230 supports up to 64 channelized ornon-channelizedT1 and E1 interfaces on a single IP + ATM multiservice gateway

The MGX 8230 converts all user information into 53-byteATM cells by using the appropriate ATM Adaptation Layer (AAL) for transport over the ATM backbone network. The individual service modules segment and reassemble (SAR) cells to eliminate system bottlenecks. The following list shows the applicable AAL for each service:

Circuit emulation services uses AAL1.

Frame Relay-to-ATMnetwork interworking uses AAL5 and Frame Relay Service Specific ConvergenceSub-layer(FR-SSCS).

Frame Relay-to-ATMservice interworking uses both transparent and translation modes to map Frame Relay to native ATM AAL5.

Frame Forwarding uses AAL5.

MGX 8230 Enclosure and Power

The MGX 8230 has a 14 single-heightslot (7double-height)chassis. This chassis can be rack mounted in a19-inchrack, or fitted with side panels to be afree-standingbox (referred to as a“stand-alone”MGX 8230). An optional mounting bracket kit is also available for mounting the MGX 8230 in23-inchracks.

Note Although the card slots in an MGX 8230 are horizontal, this manual refers to the card slots and modules assingle-heightanddouble-height.This is for consistency: the PXM1 core card and service module cards are a subset of the MGX 8250 cards that are installed vertically in an MGX 8250 chassis.

Slot Numbering and Placement

The MGX 8230 slots are populated with cards and modules according to the following rules (Figure 1-2):

The slots are numbered 1 to 7 on the left half of the chassis. The slots on the right side of the chassis are numbered 8 to 14.

Chapter 1 Introducing the MGX 8230

MGX 8230 System Overview

Each service module slot can accept one single-heightcard or be converted to accept twodouble-heightcards.

Slots are 1 and 2 are always double-heightslots and reserved for the primary and redundant MGX 8230 Processor Switch Modules (PXM1s).

Slots 7 and 14 are reserved for SRM modules only: no other service modules can be used in these two slots.

Eight single-heightslots (fourdouble-heightslots) are available for service modules.

Figure 1-2 is a conceptual drawing of an MGX 8230 showing the dimensions and the slot numbering. The slot numbering is as it appears from the front of the MGX 8230; slots 8 and 9 refer to back card slots only.

Single Height and Double Height Slots

Single-heightslots on the MGX 8230 chassis can be converted intodouble-heightslots.

When a double-heightfront card is plugged in, the left slot number is used. The back cards are numbered according to the front card numbering scheme, with the exception of slots 8 and 9 as noted below.

Since front slots 1 and 2 are always double-heightfor PXM1 processor modules, slots 8 and 9 only refer to the back card slots that correspond to the two lowersingle-heightslots on the left side of the chassis as seen from the rear.

When converting single-heightslots intodouble-heightslots the conversion must start from the bottom and be contiguous. For example, before you can convert slot 4 into double height, slot 3 must be converted first (as shown inFigure 1-3 on page 1-6).

Chapter 3, “Site Preparation” and Chapter 4, “Enclosure Installation” contain additional information on installing racks and the MGX 8230 chassis.

MGX 8230 Power System

The MGX 8230 power system is designed with distributed power architecture centered around a

-48VDC bus on the system backplane. The-48VDC bus accepts redundant DC power from either a-42to-56VDC source via optional DC power entry modules (PEMs) or from a 100 to 120 or a 200 to 240 VAC source via the optional AC Power Supply Tray. The MGX 8230 backplane distributes power via connectors on the - 48 VDC bus to eachhot-pluggableprocessor or service module. Each card incorporateson-boardDC-DCconverters to convert the-48VDC from the distribution bus voltage to the voltages required on the card.

Optional AC Power Supply

For an AC-poweredMGX 8230, an optional AC power supply tray is attached to the bottom of the MGX 8230 card cage at the factory. The AC power supply tray is onerack-unithigh, and can hold up to two AC Power Supply modules. Each AC Power Supply module can provide up to 1,200W at-48VDC and has its own AC power cord and power switch.Figure 1-4 shows the rear view of an optional AC Power Supply module. The power supplies can be configured as 1+1 redundant. If no redundancy is desired, an AC tray with one AC power supply and one AC power cord can also be ordered.

MGX 8230 Architecture

The MGX 8230 architecture is built around the switching fabric on the processor switching module (PXM1), the backplane, and the service modules. Figure 1-7 is a very simple block diagram of the MGX 8230 architecture.

The main functions of the MGX 8230 backplane are to connect cards together, terminate critical signals properly, provide -48VDC power to all cards, and set ID numbers for each slot. In addition, the MGX 8230 backplane interconnects both front cards and back cards together viapass-throughconnectors. A software readable ID on the backplane is available for software to identify that the chassis is an

MGX 8230.

The cell bus controllers (CBCs) are application-specificintegrated circuits (ASICs) and provide the interface between the switching fabric and the service modules.

Cell Bus

The MGX 8230 cell bus (CB) provides high-speedinterface between the switch fabric and the service modules.

Figure 1-8 shows the overall cell bus distribution of MGX 8230 backplane andTable 1-1 lists the specific cell bus allocation to each slot with respect to master and slave cell bus ports.

Each PXM1 supports eight master cell buses and one slave cell bus connected to the backplane. The service modules have two slave cell bus ports, one from each PXM1. The master cell bus ports are CB0 to CB7 and the PXM1 slave ports are referred to as 7S and 8S in Table 1-1.

A cell bus comprises the group of signals used to transfer data between the PXM and a service module. CB 0, 6, 1, 2, 4, and 3 are dedicated service modules, CB5 supports physical slot 6. CB7 supports physical slot 13 as well as the alternate PXM1’s slave port.

There is a connection on cell bus 7 to the alternate PXM1. A PXM1 is able to communicate with the other PXM1 using the slave cell bus port on that card. Slots 8 and 9 only refer to back card slots.

MGX 8230 Management

Firmware on each card determines the functions and operations of the module. This firmware can be upgraded by downloading new firmware with a TFTP application running on a workstation or a PC.

The current status and configuration parameters of the modules reside in a Management Information Base (MIB). The MIB is updated by the firmware in the modules whenever changes to the module status or configuration occur. The MIB can be interrogated using SNMP commands.

The MGX 8230 supports the following user interface applications:

Cisco WAN Manager (formerly StrataView Plus): a Graphical User Interface (GUI) application for connection management. This application enables operations, administration, and maintenance of WAN-multiservicenetworks.

CiscoView: a GUI application for hardware configuration.

Introduction to Core Card Sets and Service Modules

The MGX 8230 supports core cards andservice modules. The Processor Switching Module (PXM1) and optional Service Resource Module (SRM) arecore cards.

In addition, the PXM1 is part of a card set consisting of a front card, a back card, and a daughter card:

The front card contains the processing intelligence.

The daughter card contains the firmware that distinguishes the interface (OC-3,T3, E3, and so on).

The back card is a simple card that provides the electrical interface for one or more lines of a particular type.

Service modules are not combined in this manner and are never part of a card set. Instead, service modules provide the interface for transport technologies such as Frame Relay and ATM.

The MGX 8230 enclosure contains up to 8 service modules (I/O cards). The optional Service

Redundancy Modules (SRMs) provide redundancy.

Note Although technically distinct, he termscard andmodule are often used interchangeably in the field.

Summary of MGX 8230 Cards and Modules

Redundancy for Service Modules

Service modules can have either 1:1 redundancy or 1:N redundancy.

Refer to the CiscoView user documentation for instructions on using the CiscoView application to configure redundancy.

1:1 Redundancy

For 1:1 redundancy, place the card sets in adjacent slots and connect the appropriate Y-cableto the paired ports on the active and standby cards. Applicable service modules are:

MGX-FRSM-2CT3

MGX-FRSM-2T3E3

MGX-FRSM-HS2

Hot Standby

For hot standby, place the card sets in the same shelf and connect the appropriate Y-cableto the paired ports on the active and hot standby cards. The hot standby card will automatically configure itself to match the configuration of the primary card. This process may take up to eight minutes. After the configuration transfer process is completed, the transfer from the primary to the hot standby card takes less that one second regardless of the number of connections. Any subsequent changes to the primary card are automatically transferred to the hot standby card configuration so the two cards maintain the same configuration. Refer to the“Redundancy for Service Modules” section on page 1-16 for instructions for setting up a redundant pair.

Applicable service modules are:

MGX-FRSM-2CT3

MGX-FRSM-2T3E3

MGX-FRSM-HS2

To determine the hot standby status of the system, use the command dsphotstandby.

1:N Redundancy

For 1:N redundancy, an MGX Service Resource Module-3T3(MGX-SRM-3T3/C)card set is necessary. This card set supports 1:N redundancy for the following service modules:

MGX-AUSM-8T1/B

MGX-AUSM-8E1/B

Service Resource Module

Service Resource Module

A service resource module (SRM) provides three main functions for the service modules:

Bit Error Rate Testing

1:N Service Module Redundancy

Bulk Distribution Mode

See Figure 2-9 for an illustration of theMGX-SRM-3T3/Cfront card and theMGX-BNC-3T3-Mback card.

Bit Error Rate Testing

After a service module line or port is put into loopback mode, the SRM can generate a test pattern over the looped line or port, read the received looped data, and report on the error rate. This operation can be performed on a complete T1 or E1 line, on a fractional T1 or E1 line, on a SD0 bundle (N x DS0), or on a single DS0 channel. The SRM can support BERT only one line or channel at a time. BERT is capable of generating a variety of test patterns, including all ones, all zeros, alternate one zero, double alternate one zero, 223-1,220-1,215-1,211-1,29-1,1 in 8, 1 in 24, DDS1, DDS2, DDS3, DDS4, and DDS5.

1:N Service Module Redundancy

Service module redundancy provides 1:N redundancy for multiple groups of service modules (a group consists of N active and one standby service module). The redundant service module in a group must be a superset (with respect to functionality) of the cards. Upon the detection of a failure in any of the service modules, the packets destined for the failed service module are carried over the CellBus to the SRM in its chassis. The SRM receives the packets and switches them to the backup service module via the CellBus.

Bulk Distribution Mode

Each of the T3 ports can be used to support up to 28 multiplexed T1 lines, which are distributed to T1 service module ports in the switch. Called bulk distribution, this feature is performed when the SRM is in “bulk mode.” The purpose of this feature is to allow large numbers of T1 lines to be supported over T3 lines rather than over individual T1 lines.

Any T1 channel in a T3 line can be distributed to any eight port service module in any slot . Each MGX 8230 shelf can support up to 64 T1 lines.

The SRM-3T3can also be operated in “nonbulk mode” on aport-by-portbasis. For a port configured in nonbulk mode, bulk distribution is disabled and the SRM provides BERT and 1:N redundancy functions only.

Linking theMGX-SRM-3T3/Cto a destination card causes the switch to take CPE traffic through theMGX-SRM-3T3/Crather than the T1 card’s line module. Linkage is acard-levelcondition. If you link just one T1 channel on a service module to theMGX-SRM-3T3/C,the back card on the service module becomes inoperative, so you must link all other T1 ports on that service module to theMGX-SRM-3T3/Cif you want them to operate.

Module Requirements with Bulk Distribution and Redundancy

The use of bulk distribution affects the requirements for SRM and service module back cards:

With bulk distribution and 1:N redundancy support by way of the distribution bus, the service modules do not use back cards.

For just 1:N redundancy by way of the redundancy bus, the supported service modules must have back cards—includingone special redundancy back card. E1 redundancy requires theAX-R-RJ48-8EorAX-R-SMB-8E1line module, and T1 redundancy requires theR-RJ48-8T1line module.

For bulk distribution, the T3 lines connect to an external multiplexer. The T1 lines on the other side of the multiplexer connect to the CPE. The SRM converts the received traffic from its T3 lines to T1 channels and sends the data to linked service modules. For instructions on linking T1 channels and card slots to theMGX-SRM-3T3/C,seeChapter 6, “Card and Service Configuration”

Installation Requirements for the MGX-SRM-3T3/C

The following are card-levelcharacteristics that apply to any SRM installation:

Only MGX-SRM-3T3/Ccards can be installed in slots 7 and 14.

No other service modules can be installed in slots 7 and 14. These slots do not have cell bus connections. The SRM modules use a local bus to communicate with the PXM.

The PXM1 in slot 1 controls the SRM in slot 7. The PXM1 in slot 2 controlsthe SRM in slot 14.

Either SRM in slot 7 or 14 can be active (depending on the active PXM1).

ATM UNI Service Module (AUSM)

ATM UNI Service Module (AUSM)

The main function of the AUSM cards is to provide an ATM UNI/NNI interface at T1 or E1 rates so that ATM UNI user devices can transmit and receive traffic. This section contains the following information:

AUSM Features, page 2-15

AUSM Front Card Illustration and LED Description, page 2-17

Back Cards for the AUSM/B, page 2-18

AUSM Features

The MGX-AUSM-8T1/BandMGX-AUSM-8E1/B(AUSM) are multipurpose front cards that use aneight-portT1 or E1 back card to provide native ATM UNI interfaces.

A single AUSM/B card can provide hot standby redundancy for all active AUSM/B cards of the same type (1:N redundancy).

AUSM/B modules are supported by standards-basedmanagement tools, including Simple Network Management Protocol (SNMP), Trivial File Transfer Protocol (TFTP) for configuration and statistics collection, and acommand-lineinterface. Cisco’s WAN Manager service management tool provides full graphical user interface support for connection and equipment management.

Quality of Service (QoS) Management

Consistent with Cisco’s intelligent quality of service (QoS) management features, AUSM/B cards support per-VCqueuing on ingress and multipleclass-of-servicequeues on egress. AUSM/B cards fully support continuous bit rate (CBR), variable bit rate (VBR), unspecified bit rate (UBR), and available bit rate (ABR) service classes.

Inverse Multiplexing

AUSM/B cards also support ATM Forum-compliantinverse multiplexing for ATM(IMA). This capability enables multiple T1 or E1 lines to be grouped into a singlehigh-speedATM port. This n x T1 and n x E1 capability fills the gap between T1/E1 and T3/E3, providing bandwidth up to 12 Mbps

(n x T1) or 16 Mbps (n x E1), without requiring a T3/E3 circuit.

Inverse Multiplexing for ATM

ATM Forum 1.0-compliantinverse multiplexing for ATM (IMA)

Support for differential delays of up to 200 milliseconds across the constituent T1s (up to 250 ms) and E1s of an IMA group

With IMA disabled, each T1 or E1 interface configured as a single port running at full line rate

With IMA, any group of n x T1s or n x E1s can support an n x T1 or n x E1 port

With IMA, multiple IMA ports of any configuration supported per card (a specific T1 or E1 line can be in only one T1/E1 or IMA port at a time)

Upon T1/E1 circuit failure, an IMA port automatically adjusts to continue operation over remaining circuits

Frame Relay Service Modules

Frame Relay Service Modules

The primary function of the Frame Relay Service Modules (FRSM) is to convert between the Frame Relay formatted data and ATM/AAL5 cell-formatteddata. For an individual connection, you can configure network interworking (NIW), service interworking (SIW),ATM-to-FrameRelay UNI (FUNI), or frame forwarding. An FRSM converts the header format and translates the address for:

Frame Relay port number and DLCI

ATM-FrameUNI (FUNI) port number and frame address or frame forwarding port

ATM virtual connection identifier (VPI/VCI)

See Configuring Frame Relay Service, page 6-27 for instructions to configure the FRSMs.

Redundancy for Frame Service Modules

FRSMs can have either hot standby, 1:1 redundancy, or 1:N redundancy.

For 1:1 redundancy, a Y-cableis necessary.

MGX-FRSM-2CT3,MGX-FRSM-2T3E3,andMGX-FRSM-HS2use 1:1Y-cableredundancy.

For 1:N redundancy, an MGX-SRM-3T3/Cis required (noY-cabling).

Differences may exist in the way the MGX-SRM-3T3/Csupports redundancy for a particular T1 or E1 configuration. Refer to the section titled “Service Resource Module” in this chapter and the Service Resource Module description inChapter 6, “Card and Service Configuration”

Note TheMGX-FRSM-HS1/Bdoes not support redundancy.

Hot Standby

For hot standby, place the card sets in slots on the same card shelf and connect using an appropriate Y-cableto connect each hot standby pair. To view the hot standby status of the system, use thedsphotstandby command.

1:1 Redundancy

For 1:1 redundancy, place the card sets in adjacent slots and connect a Y-cablefor each pair of active and standby ports. On the CLI, configure the card for redundancy by executing theaddred command. For instructions on how to use the CiscoView application to configure redundancy, refer to the CiscoViewuser-documentation.

1:N Redundancy

1:N redundancy for the eight-portFRSMs requires anMGX-SRM-3T3/C.With 1:N redundancy, a group of service modules includes one standby module. For installation requirements, see “Service Resource Module, page 2-12”.For configuration requirements, see the section on theMGX-SRM-3T3/CinChapter 6, “Card and Service Configuration”

Frame Relay-to-ATMNetwork Interworking

Frame Relay-to-ATMnetwork interworking (NIW) supports a permanent virtual connection (PVC) between two Frame Relay users over a Cisco network or amulti-vendornetwork. The traffic crosses the network as ATM cells. To specify NIW for a connection, add the connection with achannel type of “network interworking.” For an illustration of a BPX 8620 network with NIW connections, see

Congestion Indication for NIW Connections

In addition to frame-to-celland DLCI to VPI/VCI conversion, the network interworking feature maps cell loss priority (CLP) and congestion information from Frame Relay to ATM formats. The CLP and congestion indicators can be modified for individual connections using thecnfchanmap command.

Frame Relay–to–ATMDirection

Each Frame Relay/ATM network interworking connection can be configured as one of the following DE to CLP mapping schemes:

DE bit in the Frame Relay frame is mapped to the CLP bit of every ATM cell generated by the segmentation process.

CLP is always 0.

CLP is always 1.

ATM–to–Frame Relay Direction

Each Frame Relay/ATM network interworking connection can be configured as one of the following CLP to DE mapping schemes:

If one or more ATM cells belonging to a frame has its CLP field set, the DE field of the Frame Relay frame will be set.

No mapping from CLP to DE.

Congestion Indication

Congestion on the Frame Relay/ATM network interworking connection is flagged by the EFCI bit. The setting of this feature is dependent on traffic direction, as described below.

EFCI is always set to 0.

ATM–to–FrameRelay Direction

If the EFCI field in the last ATM cell of a segmented frame received is set, then FECN of the Frame Relay frame will be set.

PVC Status Management

The management of ATM layer and FR PVC status management can operate independently. The PVC status from the ATM layer is used when determining the status of the FR PVC. However, no direct actions of mapping LMI A bit to OAM AIS is performed.

Frame Relay-to-ATMService Interworking

By specifying “service interworking” as the channel type when adding a Frame Relay PVC to an FRSM, all PVC data is subject to service interworking translation and mapping in both the Frame Relay–to–ATMandATM–to–FrameRelay directions.Figure 2-13 is an illustration of typical SIW connections.

Cell Loss Priority

In addition to frame-to-cellandDLCI-to-VPI/VCIconversion, the SIW feature maps cell loss priority (CLP) and congestion information from FrameRelay-to-ATMformats and isFRF.8-compliant.It provides full support for routed and bridged PDUs, transparent and translation modes, and VP translation. The CLP and congestion parameters can be modified for individual connections with thecnfchanmap command.

Frame Relay–to–ATMDirection

Each Frame Relay– to–ATMservice interworking connection can be configured as one of the following Discard Eligibility (DE) to Cell Loss Priority (CLP) schemes:

DE bit in the Frame Relay frame is mapped to the CLP bit of every ATM cell generated by the segmentation process of the frame.

CLP is always 0.

CLP is always 1.

ATM–to–FrameRelay Direction

Each Frame Relay– to–ATMservice interworking connection can be configured as one of the following CLP to DE mapping schemes:

If one or more ATM cells belonging to a frame has its CLP set, the DE field of the Frame Relay frame will be set.

DE is always 0.

DE is always 1.

Setting up the cell loss priority option is accomplished through the MGX 8220 cnfchanmap (configure channel map) command.

Congestion Indication

Frame Relay–to–ATMDirection

Each Frame Relay– to–ATMservice interworking connection can be configured as one of the following Forward Explicit Congestion Notification (FECN) toExplicit-ForwardCongestion Indicator (EFCI) schemes:

FECN bit in the Frame Relay frame is mapped to the EFCI bit of every ATM cell generated by the segmentation process of the frame.

EFCI is always 0.

EFCI is always 1.

ATM–to–FrameRelay Direction

Frame Relay– to–ATMservice interworking connections use the following EFCI to FECN/BECN mapping schemes:

If the EFCI bit in the last ATM cell of a segmented frame received is set to 1, the FECN of the Frame Relay frame will be set to 1.

BECN is always set to 0.

Setting up the congestion indication option is accomplished through the cnfchanmap (configure channel map) command.

Chapter 2 Module and Service Descriptions

Frame Relay Service Modules

Command and Response Mapping

Command/Response Mapping is provided in both directions.

Frame Relay–to–ATMDirection

The FRSM maps the C/R bit of the received Frame Relay frame to the CPCS-UUleast-significantbit of the AAL5 CPCS PDU.

ATM to Frame Relay Direction

Theleast-significantbit of theCPCS-UUis mapped to the C/R bit of the Frame Relay frame.

Translation and Transparent Modes

Each service interworking (SIW) connection can exist in either translation ortransparent mode. In translation mode, the FRSM translates protocols between the FR NLPID encapsulation (RFC 1490) and the ATM LCC encapsulation (RFC 1483). In transparent mode, the FRSM does not translate. Translation mode support includes address resolution by transforming address resolution protocol (ARP, RFC 826) and inverse ARP (inARP, RFC 1293) between the Frame Relay and ATM formats.

Frame Forwarding

The FRSM card can be configured as “Frame Forwarding” on a port-by-portbasis.

Frame forwarding operates the same as standard Frame Relay except that the FRSM:

The 2-byteQ.922 header is not assumed/interpreted.

All frames received are mapped to a specific connection if it exists. Otherwise, the frames are dropped.

No DE/CLP or FECN/EFI mapping is performed.

“Illegal header count” and “Invalid DLCI” statistics are not kept.

“Discarded frame count due to no connection” statistic is kept.

ATM Frame-to-UserNetwork Interface

All FRSMs support the ATM Frame-basedUser-to-NetworkInterface (FUNI). When a frame arrives from the FUNI interface, the FRSM removes the2-byteFUNI header and segments the frame into ATM cells by using AAL5. In the reverse direction, the FRSM assembles ATM cells from the network into a frame by using AAL5, adds a FUNI header to the frame, and sends it to the FUNI port.

Loss Priority Indication

Loss Priority Indication mapping is provided in both directions:

FUNI-to-ATMDirection

The CLP bit on the FUNI header is mapped to the CLP bit of every ATM cell that is generated for the FUNI frame.

ATM-to-FUNIDirection

CLP bit in the FUNI header is always set to 0.

Congestion Indication

The FRSM maps congestion indication in both directions:

Congestion Indication mapping is provided in both directions

FUNI-to-ATMDirection

EFCI is set to 0 for every ATM cell generated by the segmentation process.

ATM-to-FUNIDirection

If the EFCI field in the last ATM cell of a received segmented frame is set to 1, the CN bit in the FUNI header is set to 1. The two reserve bits (the same positions as C/R and BECN in Frame Relay header) are always set to 0.

Types of Frame Service Modules

There are three types of FRSMs:

FRSMs for T1 and E1 Lines, page 2-27.

FRSMs for T3 and E3 lines, page 2-32.

Circuit Emulation Service Modules

The main function of the Circuit Emulation Service Module (CESM) is to provide a constant bit rate (CBR) circuit emulation service by converting data streams into CBR AAL1 cells for transport across an ATM network. The CESM supports the CES-ISspecifications of the ATM Forum.

There are two types of CESM modules:

CESM for T1 and E1 lines, page 2-45.

CESM for T3 and E3 lines, page 2-50.

CESM for T1 and E1 lines

The eight-portAX-CESM-8T1andAX-CESM-8E1models allow individual physical ports to be configured for structured or unstructured data transfer. The CESM providesconstant-bit-rate(CBR) services over an ATM network. It allowscircuit-basedequipment, such as PBXs, to be interconnected over an ATM backbone via CBR connections. The eight port CESM cards support both channelized (n x 64 Kbps) and unchannelized (T1/E1)circuit-basedequipment. In ATM Forum terminology, the terms structured data transfer (SDT) and unstructured data transfer (UDT) are used for channelized and unchannelized circuit emulation, respectively.

In addition, flexible clocking mechanisms are provided to meet different application requirements. Synchronous clocking and asynchronous clocking, using either SRTS or Adaptive clock recovery, are both supported.

As an enhancement, dynamic bandwidth allocation is supported via on-hook/off-hookdetection to reduce backbone bandwidth consumed when it is not required by the applications. This allows other traffic streams, such as VBR and ABR traffic, to take advantage of the bandwidth normally reserved for the circuit traffic.

CESM T1 and E1 Features

The eight port CESM cards offer the following key features for both T1 and E1 interfaces:

Standards-basedAAL1

Compliant with ATM Forum CES---V.2.0

Choice of structured or unstructured data transfer per physical interface

Time slots must be contiguous for n x 64-kbpsfractional T1/E1 service

Any n x 64-kbpschannel can be mapped to any virtual circuit (VC)

Choice of partially filled AAL1 cells per VC

Supports Super Frame (SF) and Extended Superframe (ESF) framing modes

Supports synchronous clocking for both UDT and SDT

Supports asynchronous clocking for UDT, with SRTS and adaptive clock recovery methods

ON/OFF hook detection and idle suppression using channel-associatedsignaling (CAS)

Supports physical T1/E1 interfaces via back cards or higher speed channelized interfaces using TDM infrastructure on backplane (SRM)

Traffic is mapped between service interfaces and the ATM backplane using standards-compliantadaptation. Consistent with Cisco's intelligentquality-of-service(QoS) management features, CESM cards supportper-VCexpress queuing.

Chapter 2 Module and Service Descriptions

Frame Relay Service Modules

A single T1/E1 CESM card can provide standby redundancy for all active CESM cards of the same type in the shelf (1:N redundancy), with SRM.

CESM cards are supported by standards-basedmanagement tools, including Simple Network Management Protocol (SNMP), Trivial File Transfer Protocol (TFTP) for configuration and statistics collection, and acommand-lineinterface. Cisco WAN Manager also provides full graphical user interface (GUI) support for connection and equipment management.

1:N Redundancy for the CESM T1/E1

Redundancy for the AX-CESM-8T1andAX-CESM-8E1is available through theMGX-SRM-3T3/C.

1:N redundancy requires that the group contain one redundancy back card.

The redundancy back card must be the special R-RJ45version(AX-R-RJ48-8T1-LMorAX-R-SMB-8E1-LM).

For information on installation requirements, refer to the Service Resource Module, page 2-12.For configuration requirements, see the“Service Resource Module” section on page 6-49.

For instructions on how to use the CiscoView application to configure redundancy, refer to the CiscoView user-documentation.

CESM for T3 and E3 lines

The MGX-CESM-T3/E3supports unstructured data transfer over a single T3 or E3 physical port at speeds of 44.736 Mbps (T3) or 34.368 Mbps (E3). Only synchronous timing is supported.

MGX-CESM-T3/E3is atwo-cardset consisting of a front card and either a T3 back card or an E3 back card. Each back card provides two T3 or E3 ports (each port consisting of two BNC connectors). Only port one is available on the back card when used with theCESM-T3/E3front card. 1:1 redundancy is supported through aY-cableon the line module back cards.

Figure 2-26 on page 2-52 is an illustration of theMGX-CESM-T3/E3front card.

An illustration of the CESM back card for T3 lines is shown in Figure 2-27 on page 2-53.

An illustration of the CESM back card for E3 lines is shown in Figure 2-28 on page 2-54.

CESM-T3/E3Features

CESM cards support circuit emulation services using standards-basedadaptation layers over ATM. TheCESM-T3E3uses AAL1 for T3 or E3 unstructured transfer mode operation, per the ATM Forum's Circuit Emulation Specification, Version 2.0:

Unstructured Support: supports T3/E3 unstructured data transfer.

Synchronous clocking: synchronous timing mode only supported. Must derive clock from shelf.

Onboard BERT: BERT support using on board BERT controller. BERT commands executed on T3/E3 card.

Maximum number of connections: Maximum number of connections is one. In the unstructured mode, one logical port is used to represent the T3/E3 line and one connection is added to the port to emulate the circuit.

Programmable egress buffer size and CDV tolerance settings are supported for flexible support of jitter and latency requirements.

Bit count integrity is maintained when AAL1 lost-cellcondition is detected.

The CESM card provides ingress/egress data and signaling trunk conditioning per VC as per ATM Forum CES V2.0.

T3/E3 CESM cards can be Y-cabledto provide 1:1 hot standby redundancy of the CESM.

CESM cards are supported by standards-basedmanagement tools, including SNMP, TFTP (for configuration/statistics collection), and acommand-lineinterface. The Cisco WAN Manager and CiscoView tools also provide full graphical user interface management support.

Voice Service: The VISM

The Voice Interworking Service Module (VISM) is a front and back card set designed to transport digitized voice signals across a packet network. This provides an interface or gateway between conventional voice TDM networks and networks based upon packet switching technology.

There are two types of VISM front cards:

MGX-VISM-8T1:supports up to eight T1 lines carrying digitized voice

MGX-VISM-8E1:supports up to eight E1 lines carrying digitized voice.

VISM Documentation

Installation, configuration and support for the VISM services are not included in this manual. For more information on the VISM, refer to the following Cisco Systems publications:

For information on VISM features and configuration, refer to Voice Interworking Service Module Installation and Configuration.

For up to date information on VISM version support and features, refer to the Software Release Notes Cisco WAN MGX 8850, 8230, and 8250 Software.

Summary of Features Supported with VISM 2.0.1

The following features are supported with VISM 2.0.1 on the MGX 8230.

Note The MGX 8230 supports VISM 2.0.1 and higher. All of the features available in VISM 1.5.5 are also available in version 2.0.1

VoIP using RTP (RFC 1889)

VISMR1.5 supports standards-basedVoIP using RTP (RFC1889) and RTCP protocols. This allows VISM to interwork with other VoIP Gateways.

VoAAL2 (With sub-cellmultiplexing) PVC

The VISM supports standards-compliantAAL2 adaptation for the transport of voice over an ATM infrastructure. AAL2 trunking mode is supported.

Chapter 2 Module and Service Descriptions

Frame Relay Service Modules

T3 Interfaces (via SRM Bulk Distribution)

T3 interfaces are supported using the SRM’s bulk distribution capability. In this case, the T3 interfaces are physically terminated at the SRM module. The SRM module breaks out the individual T1s and distributes the T1s via the TDM backplane bus to the individual VISM cards for processing.

Echo Cancellation

The VISM provides on-boardecho cancellation on aper-connectionbasis. Up to 128 msecuser-configurablenear-enddelay can be canceled. The echo cancellation is compliant with ITU G.165 and G.168 specifications.

Voice Activity Detection (VAD)

VISM uses VAD to distinguish between silence and voice on an active connection. VAD reduces the bandwidth requirements of a voice connection by not generating traffic during periods of silence in an active voice connection. At the far-end,comfort noise is generated.

Fax/Modem Detection for ECAN and VAD Control

The VISM continually monitors and detects fax and modem carrier tones. When carrier tone from a fax or modem is detected, the connection is upgraded to full PCM to ensure transparent connectivity. Fax and modem tone detection ensures compatibility with all voice-gradedata connections.

CAS Tunneling via AAL2 (For AAL2 Trunking Mode)

The VISM in AAL2 mode facilitates transport of CAS signaling information. CAS signaling information is carried transparently across the AAL2 connection using type 3 packets. In this mode, VISM does not interpret any of the signaling information.

PRI Tunneling via AAL5 (For AAL2 Trunking Mode)

VISM supports transport of D-chsignaling information over an AAL5 VC. The signaling channel is transparently carried over the AAL5 VC and delivered to thefar-end.In this mode, VISM does not interpret any of the signaling messages.

Voice CAC

VISM can be configured to administer Connection Admission Control (CAC) so that the bandwidth distribution between voice and data can be controlled in AAL2 mode.

Type 3 Packet for DTMF

The VISM in AAL2 mode facilitates transport of DTMF signaling information. DTMF information is carried transparently across the AAL2 connection using type 3 packets.

Dual (Redundant) PVCs for Bearer/Control

The VISM provides the capability to configure two PVCs for bearer/signaling traffic terminating on two external routers (dual-homing).VISM continually monitors the status of the active PVC by using OAM loopback cells. Upon detection of failure, the traffic is automatically switched over to the backup PVC.

64 K Clear Channel Transport

The VISM supports 64 Kbps clear channel support. In this mode, all codecs are disabled and the data is transparently transported through the VISM.

DTMF Relay for G.729

In VoIP mode, DTMF signaling information is transported across the connection using RTP NSE (Named Signaling Event) packets

MGCP 0.1 for VoIP with Softswitch Control

VISM supports Media Gateway Control Protocol (MGCP) Version 0.1. This open protocol allows any Softswitch to interwork with the VISM module.

Resource Coordination via SRCP

Simple Resource Control Protocol (SRCP) provides a heartbeat mechanism between the VISM and the Softswitch. In addition, SRCP also provides the Softswitch with gateway auditing capabilities.

Full COT Functions

VISM provides the capability to initiate continuity test as well as provide loopbacks to facilitate continuity tests when originated from the far-end.

Courtesy Down

This feature provides a mechanism for graceful upgrades. By enabling this feature, no new calls are allowed on the VISM while not disrupting the existing calls. Eventually, when there are no more active calls, the card is ready for a upgrade and/or service interruption.

PRI Backhaul to the Softswitch Using RUDP

The PRI backhaul capability provides PRI termination on the VISM with the Softswitch providing call control. ISDN Layer 2 is terminated on the VISM and the layer 3 messages are transported to the Softswitch using RUDP.

Latency Reduction (<60 ms round-trip)

Significant improvements have been made to bring the round-tripdelay to less than 60 ms.

Codecs Preference

VISM provides the capability to have the codecs negotiated between the two end-pointsof the call. The VISM can be configured, for a givenend-point,to have a prioritized list of codecs. Codec negotiation could be directly between theend-pointsor could be controlled by a Softswitch

31 DS0 for E1 with 240 Channels Only

While all 31 DS0s on a E1 port can be used, there is a limitation of 240 channels per card.

VISM Redundancy

The VISM redundancy strategy is the same as for any of the eight port cards in the MGX 8230.

For VISM-8T1,1:N redundancy is supported using theSRM-3T3.

For VISM-8E1,1:N redundancy is supported only via LMs using theSRM-3T3or theSRM-T1E1.

1octave/minute, two sweeps.

Non-operating:5 Hz to 500 Hz at 1.0 g peak, limited to0.50-inchdouble amplitude, sine wave,

1octave/minute, two sweeps.

Power

For AC power use, an AC power source must be available within 6 feet (1.8 m) of the MGX 8230. For systems using a DC source, Cisco does not supply the DC power cord, so the user or installer determines the wire length and the distance to the DC source. The wire should be 10 AWG (4 square millimeters).

Heat Dissipation

A fully loaded, AC-poweredMGX 8230 dissipates up to 4,800 BTUs (1.4 KW hour). ADC-poweredMGX 8230 dissipates up to 4,100 BTUs.

Weight

A fully loaded, DC-poweredMGX 8230 can weigh up to 120 lbs (54.3 Kgs). A fully loadedAC-poweredMGX 8230 can weigh up to 150 lbs (68.03 Kgs).

Caution If you move aCisco-suppliedcabinet, do not push it at its sides. Push at the front or back.

Flooring

Raised flooring with sufficient under-floorspace for external cabling is best.

Mounting

The location of the IGX or BPX switch, which has a co-locatedMGX 8230 IP + ATM Edge Concentrator, should accommodate the routing of the data cables and the termination of the telephone company’s or common carrier’s circuits.

Electrostatic Discharge

The building should provide adequate grounding to prevent damage from electrostatic discharge. See the sections “Bonding and Grounding” in the IGX or BPX installation documents for specific details.

In addition, the MGX 8230 comes with a wrist strap that you can connect to the rear of the chassis near the ground lug or to a convenient point on the front of the chassis. You should put on a wrist strap before handling any cards.

Chapter 3 Site Preparation

Power and Grounding

Power and Grounding

This section describes the requirements for electrical power and grounding the switch and the site. These requirements apply to Central Office (CO) and Private Enterprise (PE) sites.

AC Power Circuit Breakers

AC power must come from dedicated, AC branch circuits. Each circuit must be protected by a dedicated, two-polecircuit breaker. The circuit breakers at the source must have a rated current and trip delay greater than those of the MGX 8230 circuit breaker. Cisco recommends that the site have a 20A,2-poleAC circuit breaker with a long trip delay at each branch circuit.

The MGX 8230 uses a 20A, 2-polecircuit breaker for each AC input. The manufacturer of this circuit breaker is ETA. The ETA part number is8340-F120-P1P2-B2H020A.

DC Power Circuit Breakers

For a DC-poweredMGX 8230, verify that its power comes from a dedicated DC branch circuit. This branch circuit must be protected by a dedicated circuit breaker. Cisco Systems recommends the site have a dedicated 30 Amp circuit breaker with a medium trip delay at each branch circuit.

A DC-poweredMGX 8230 uses a single pole 30 Amp circuit breaker with a short trip delay on each–48Vinput. The circuit breaker manufacturer is ETA. The part number is ETA8340-F110-PIKI-A2H030A.

Electrical Power for AC-PoweredNodes

The MGX 8230 AC power requirement is a voltage range of 100 to 120 or 200 to 240 VAC. A worst-case90 VAC is allowed. Refer to Appendix A, “Technical Specifications.” An AC power source must be available within 6 feet (1.8 m) of the system and easily accessible. Before turning on the power, verify that each power source to the MGX 8230 comes from a dedicated branch circuit.

The power receptacles to which the node connects must be of the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth at the service equipment.

Cisco can provide AC power cords with the following plugs:

20 A NEMA Lb-20P,twist lock plug (domestic U.S.)

13 A 250 Vac BS1363, 3-prongfused plug (UK, Ireland)

CEE 7/7 (Continental Europe)

AS3112 (Australia/New Zealand)

CEI23-16/VII(Italy)

NEMA5-15P125V/15 A3-prongplug, grounding type (North America)

Electrical Power for a DC-PoweredMGX 8230

Only a - 48 VDC supply that complies with the Safety Extra Low Voltage (SELV) requirements of EN 60950 can connect to the DC input.

Chapter 3 Site Preparation

Power and Grounding

For DC supply connections, consult local or national codes for conductor sizing. Conductors must be suitable for 30 Amps. Wiring that is 10 AWG (4 square millimeters) is adequate.

Bonding and Grounding

To maintain the full EMI and EMC integrity of this equipment, it must be bonded to an integrated ground plane or anisolated ground plane network. The purpose of this requirement is to mitigate the damaging effects to equipment from electrostatic discharge and lightning. Refer to the latest edition of ITU Recommendation K.27 or BellcoreGR-1089-CORErequirements to ensure that the correct bonding and grounding procedures are followed. As recommended in these documents, a frame bonding connection is provided on theCisco-suppliedcabinet forrack-mountedsystems.

Refer to the section “Making the Frame Bonding (Ground) Connection” in the IGX or the BPX installation documents for information on how to make a connection.

Note Except for the AC power supply module, every module in arack-mountsystem relies on the rack itself for grounding. Therefore, the rack must be properly connected to protective earth before operating the system.

A DC-powerednode must have grounding conductors that connect at two separate locations, as follows:

The grounding conductor provided with the supply source must connect to the correct terminal of the Power Entry Module (PEM).

A grounding conductor as described previously must connect to the appropriate terminal of a rack assembly or to the grounding point on the lower-rightcorner of the MGX 8230 chassis rear panel.

Wiring a Mixed Ground System with Redundant Supplies

A mixed ground system appears in Figure 3-3.This figure shows safety and earth grounds and the primary and redundant DC sources Battery A and Battery B. Individual ground conductors are labeled Z1, Z2, ..., Z5. The Z represents the impedance of the ground conductor between a chassis, for example, and a connection to the building’s ground system. The numbers 1, ..., 4 represent building ground points and indicate that an impedance can exist between different points in the ground system of the building. Each of these symbols indicate that a voltage drop may result (but must not exceed 2 percent of the referenced voltage). SeeTable 3-1 for a definition of eachZ1–Z5.
