Chapter 1 Introducing the MGX 8230

Summary of MGX 8230 Cards and Modules

Service Resource Module (SRM)

•Service Resource Module (MGX-SRM-3T3/C)

The optional SRM provides three major functions for service modules; bit error rate tester (BERT) of T1 and E1 lines and ports, loops back of individual N x 64 channels toward the customer premises equipment (CPE), and 1:N redundancy for the service modules.

Frame Relay Service Modules (FRSM)

•Frame Service Module for eight T1 ports (AX-FRSM-8T1)

The AX-FRSM-8T1 provides interfaces for up to eight fractional T1 lines, each of which can support one 56 kbps or one Nx64 kbps FR-UNI, FR-NNI port, ATM-FUNI, or a Frame forwarding port. The AX-FRSM-8T1 supports fractional and unchannelized T1 port selection on a per-T1 basis.

•Frame Service Module for eight E1 ports (AX-FRSM-8E1)

The AX-FRSM-8E1 provides interfaces for up to eight fractional E1 lines, each of which can support one 56 kbps or one Nx64 kbps FR-UNI, FR-NNI, ATM-FUNI, or Frame forwarding port. The AX-FRSM-8E1 supports fractional and unchannelized E1 port selection on a per-E1 basis.

•Frame Service Module for eight channelized T1 ports (AX-FRSM-8T1-C)

The AX-FRSM-8T1-C allows full DS0 and n x DS0 channelization of the T1s. Each interface is configurable as up to 24 ports running at full line rate, at 56 or n x 64 kbps for a maximum of 192 ports per FRSM-8T1-C.

•Frame Service Module for eight channelized E1 ports (AX-FRSM-8E1-C)

The AX-FRSM-8E1-C allows full DS0 and n x DS0 channelization of the E1s. Each interface is configurable as up to 31 ports running at full line rate, at 56 or n x 64 kbps for a maximum of 248 ports per FRSM-8E1-C.

•Frame Service Module for T3 and E3 (MGX-FRSM-2E3T3)

The MGX-FRSM-2E3/T3 provides interfaces for two T3 or E3 Frame Relay lines, each of which can support either two T3 lines (each at 44.736 Mbps) or two E3 lines (each at 34.368Mbps) FR-UNI, ATM-FUNI, or Frame Forwarding port.

•Frame Service Module for channelized T3 (MGX-FRSM-2CT3)

The MGX-FRSM-2CT3 supports interfaces for two T3 channelized Frame Relay lines. Each interface supports 56 Kbps, 64 Kbps, Nx56 Kbps, Nx64 Kbps, T1 ports that can be freely distributed across the two T3 lines.

•Frame Service Module for high speed serial (MGX-FRSM-HS1/B)

The FRSM-HS1/B supports the 12-in-1 back card. This back card supports up to four V.35 or X.25 serial interfaces. This card also supports the two port HSSI back cards with SCSI-2 connectors.

•Frame Service Module for unchannelized HSSI (MGX-FRSM-HS2/B)

The MGX-FRSM-HS2/B supports interfaces for two unchannelized HSSI lines. Each interface supports approximately 51 Mbps; with both lines operating, maximum throughput is 70 Mbps.

ATM UNI Service Modules (AUSM)

•ATM UNI Service Module for T1 (MGX-AUSM/B-8T1)

The MGX-AUSM/B-8T1 provides interfaces for up to eight T1 lines. You can group N x T1 lines to form a single, logical interface (IMA).

•ATM UNI Service Module for E1 (MGX-AUSM/B-8E1)

The MGX-AUSM/B-8E1 provides interfaces for up to eight E1 lines. You can group N x T1 lines to form a single, logical interface (IMA).
