Chapter 5 Preparing SRM Cards for Communications
Linking Service Module Lines to SRM Channels, VTs, or VCs
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
Step 3 Enter the dsplink <LogicalSRMslot.Line> command to verify your configuration. Replace
<LogicalSRMslot.Line> with the slot number of the SRM card and the line number you wish to view. In
the following example, the user displays the configuration for line 1 on the SRM card represented by
logical slot 15.

Table 5-7 shows the correlation between VTs, virtual tributary groups (VTGs), and SRM link numbers
when a SRME or SRME/B line is configured for the SONET line type.
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.
