MGX 8220 Cards

MGX 8220 System Overview

MGX 8220 cards are always installed as a pair consisting of a front card (function module) and a matching back card (line module) in the same slot, except for the SRM-T1E1 card which only has a front card. Communication between slots is achieved through buses in the shelf backplane.

Release 3.0 consists of the following module pairs:

•MGX 8220 Shelf Controller(ASC)

This is a pair of cards providing overall control of the shelf and providing line interfaces to maintenance and control ports which are used for user conﬁguration and management of the shelf.

•

Broadband Network Module (BNM-T3)

This is a pair of cards which together provide the interface to the attached BPX switch over a T3 ATM interface.

Broadband Network Module (BNM-E3)

This is a pair of cards which together provide the interface to the attached BPX switch over a E3 ATM interface.

Frame Service Module for T1 (FRSM-4T1)

This card provides interfaces for up to four T1 lines, each of which can support one 56 kbps or one Nx64 kbps FR-UNI, FR-NNI port, ATM-FUNI, or Frame Forwarding port.

Frame Service Module for T1 channelized (FRSM-4T1-C)

This card provides interfaces for up to four T1 lines, each of which can support multiple (up to 24) 56 kbps or Nx64 kbps FR-UNI, FR-NNI, ATM-FUNI, or Frame Forwarding port.

Frame Service Module for E1 (FRSM-4E1)

This card provides interfaces for up to four E1 lines, each of which can support one 56 kbps or one Nx64 kbps FR-UNI, FR-NNI, ATM-FUNI, or Frame Forwarding port.

•Frame Service Module for E1, channelized (FRSM-4E1-C)

This card provides interfaces for up to four E1 channelized frame relay lines, each of which can support multiple (up to 31) 56 kbps or Nx64 kbps FR-UNI, FR-NNI, ATM-FUNI, or Frame Forwarding port.

•

ATM UNI Service Module for T1 (AUSM-4T1)

This card provides interfaces for up to four T1 lines, each of which can support one T1 ATM UNI or ATM NNI.

ATM UNI Service Module for E1 (AUSM-4E1)

This card provides interfaces for up to four E1 lines, each of which can support one E1 ATM UNI or ATM NNI.

Circuit Emulation Service Module for T1 (CESM-4T1)

This card provides interfaces for up to four T1 lines, each of which is a 1.544 Mbps unstructured synchronous data stream.

Circuit Emulation Service Module for E1 (CESM-4E1)

This card provides interfaces for up to four E1 lines, each of which is a 2.048 Mbps unstructured synchronous data stream.

Inverse Multiplexing for ATM Trunk Module—T3 to T1 (IMATM-T3-T1)

This card acts as an extension of the BPX BNI card and permits the BPX ATM trunk to be used over multiple (up to 8) T1 lines instead of a single T3 line.

•Inverse Multiplexing for ATM Trunk Module—E3 to E1 (IMATM-E3-E1)

This card acts as an extension of the BPX BNI card and permits the BPX ATM trunk to be used over multiple (up to 8) E1 lines instead of a single E3 line.
