Chapter 5 Preparing SRM Cards for Communications
Linking Service Module Lines to SRM Channels, VTs, or VCs
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.
mgx8830b.1.PXM.a > addlink <SrmStartLinkIf> <NumberOfLinks> <TargetIF>
Table 5-6 describes the command parameters.
In the following example, 8 links are created for all 8 lines on the service module in slot 14. The starting
link number on the SRM is 1.
M8850_LA.8.PXM.a > addlink 15.1.1 8 14.1
Table 5-6 addlink Command Parameters
Option Description
SrmStartLinkIf Logical SRM slot and link number, in the form of slot.line.link.
For a 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 Table 5-7,
Table 5-8, and Table 5-9.
NumberOfLinks The number of links you want to configure with this command. Replace
NumberOfLinks with a number from 1 through 8. If you specify 1, you will
create one link. If you specify 8, you can configure links for all 8 lines on a
service module at the same time.
TargetIF Targeted starting line in the format slot.line. To see which slots are hosting
service modules that can use bulk distribution, enter the dspcds command and
note the 8-port T1 service modules that are in the same bay as the SRM card.
The line is the starting line number and defines which line will be the first of the
group of lines to be configured. For example, if you enter 1 for the number of
links to configure and 4 for the target line number, only one link will be
configured for line 4 on the target service module. If you specify 8 for the
number of links and 1 for the target line, all 8 lines on the target service module
are configured for bulk distribution.
