Introduction

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

•

•

•

Frame Relay port number and DLCI

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

ATM virtual connection identifier (VPI/VCI)

Types of Frame Service Modules

The models of the FRSM include eight-port T1 and E1 cards and very high-speed modules. Higher speed modules support unchannelized E3 and HSSI as well as channelized and unchannelized T3.

Very High Speed Frame Service Modules

The Very High Speed Frame Service Modules (FRSM-VHS) support Frame Relay services on T3, E3, and HSSI interfaces. Up to 24 FRSM-VHS cards in any combination can operate in the switch. They should occupy upper slots whenever possible. The FRSM-VHS group on an MGX 8850 node consists of the:

•MGX-FRSM-2CT3, which provides channelized Frame Relay service for up to 1000 user connections over two T3 lines on the BNC-2T3 back card (or line module).

•MGX-FRSM-2T3E3, which provides unchannelized (clear-channel) Frame Relay service for up to 1000 user connections over two T3 lines (44.736 Mbps each) or two E3 lines (34.368 Mbps each) on a BNC-2T3 or BNC-2E3 back card. The MGX-FRSM-2T3E3 can also support subrate T3 or E3 for tiered DS3 on each physical port.

•MGX-FRSM-HS2, which provides unchannelized Frame Relay service for up to 1000 user-connections over two HSSI lines on the SCSI2-2HSSI back card. The maximum rate for the card is 70 Mbps. Each port can operate either as DTE or DCE with incremental rates of NxT1 or NxE1 up to 52 Mbps.

Eight-Port Channelized and Unchannelized Frame Service Module

The AX-FRSM-8T1 and AX-FRSM-8E1 provide unchannelized Frame Relay service for up to 1000 user-connections on 8 T1 or E1 lines. The AX-FRSM-8T1c and AX-FRSM-8E1c provide channelized Frame Relay service for up to 1000 connections.
