Chapter 5 Preparing SRM Cards for Communications
Linking Service Module Lines to SRM Channels, VTs, or VCs
Once you establish a link for a service module line, bulk distribution is enabled for the entire service
module and all lines must use bulk distribution. Although bulk distribution will work with a service
module back card installed, the service module cannot use the back card once bulk distribution is enabled
on any line.
Note
The SRME and SRME/B cards support bulk distribution to E1 cards only when the SDH line type is
selected while configuring a line. The SRM-3T3/C card does not support bulk distribution to E1 service
modules.
To link a service module line to an SRM channel, VT, or VC and enable bulk distribution, use the
following procedure:
Step 1
Establish a configuration session with the active PXM using a user name with GROUP1_GP privileges
or higher.
Step 2
Enter the addlink command on the active PXM to bring up a link between a service module line and an
SRM channel, VT, or VC.

Description
SrmStartLinkIf
Logical SRM slot and link number, in the form of slot.line.link.
For a Cisco MGX 8850 (PXM1E/PXM45) switch or a Cisco MGX 8880 Media
Gateway, replace slot with 15 for the upper bay or 31 for the lower bay. For a
Cisco MGX 8830 switch, the logical slot number is 7.
Replace line with 1 for SONET/SDH interfaces or a number in the range of 1
to 3 for T3 interfaces.
The link number identifies the starting link number on the SRM line you are
configuring. The link number must be available (no other line connected to it).
Replace link with a number in one of the following ranges:
•
SONET/SDH interfaces, T1 line tributary type configuration
(VT15/VC11) = range 1 to 84
•
SONET/SDH interfaces, E1 line tributary type configuration (VT2/VC12)
= range 1 to 63
•
T3 interfaces, range 1 to 28
Note
T3 links 1 through 28 for each line connect to channels 1 to 28,
respectively in the respective T3 line. The links within a SONET SDH
line map to the VTs and VCs within a line as listed in
,
, and
