Chapter 5 Preparing SRM Cards for Communications
Configuration Quickstart for Bulk Distribution on SRMs Configured for SONET/SDH
When planning for bulk distribution, consider the following guidelines:
•
Bulk distribution works with T1 and E1 service modules. Refer to the Cisco MGX 8850
(PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Hardware Installation
Guide, Releases 2 Through 5, to see which service modules support bulk distribution.
•
The Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880
Hardware Installation Guide, Releases 2 Through 5, describes the physical planning requirements
for installing hardware to support bulk distribution. If these requirements are not met, bulk
distribution will not work properly.
•
When a service module is configured to use bulk distribution, this service is applied to all lines on
the service module and no back cards are required.
•
A standalone or redundant SRM-3T3/C configuration can support up to 80 T1 channels, each of
which supports a service module T1 port. These channels can be divided between up to 10 card slots
per bay.
•
A standalone or redundant SRME/B with a BNC-3T3-M back card can support up to 84 T1 channels,
each of which supports a service module T1 port. These channels can be divided between up to 11
card slots per bay.
•
The maximum number of E1 channels is 63, each of which supports a service module E1 port. These
channels can be divided between up to 8 card slots per bay.
•
A standalone or redundant SRME or SRME/B SONET/SDH configuration can support up to 84 T1
channels or 63 E1 channels per bay, and these channels can be divided between all 12 card slots in
the bay.
This chapter provides quickstart procedures for configuring SRM cards, and it provides the following
additional procedures that describe the steps in the quickstart procedures:
•
•
Establishing Redundancy Between SONET/SDH Lines with APS
•
Linking Service Module Lines to SRM Channels, VTs, or VCs
Note
SRM configuration is done from the PXM card. The software does not allow you to use the cc command
switch to an SRM.
Note
The Cisco MGX 8950 does not support SRM cards.
Configuration Quickstart for Bulk Distribution on SRMs
Configured for SONET/SDH
The quickstart procedure in this section summarizes how to configure bulk distribution on SRME and
on SRME/B cards configured for SONET/SDH interfaces. This procedure is a quick reference for those
who already have configured Cisco MGX 8850 (PXM1E/PXM45) and Cisco MGX 8830 switches.
