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.

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.
