Chapter 5 Preparing SRM Cards for Communications
Setting Up SRM Lines
Step 4 To verify your configuration changes, enter the dspln -sonet <X.1> command. Replace X with the slot
number of the SRM you are configuring.
Configuring T3 Lines
The following procedure describes how to configure T3 lines on SRM-3T3/C cards and on SRME/B
cards with T3 interfaces.
Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2 If you do not know the line number you want to configure, enter the dsplns command to display a list
of the lines.
mgx8830b.1.PXM.a > dsplns <logical slot>
Remember that you cannot configure a line until you have brought it up as described in the section,
“Bringing Up Lines.”
In the following example, the user displays the line numbers for the SRM in slot 7.
Lampoon.1.PXM.a > dsplns 7
Line Line Line Line Length OOF AIS

7.2 Down dsx3CbitPar NoLoop 00000001 3Of8Bits Check
7.3 Down dsx3CbitPar NoLoop 00000001 3Of8Bits Check
Step 3 To display the current configuration of a line, enter the dspln -ds3 <X.line> command.
If you are configuring a Cisco MGX 8850 (PXM1E/PXM45) switch, replace X with 15 for an SRM in
the upper bay, or 31 for an SRM in the lower bay. If you are configuring a Cisco MGX 8830 switch,
replace X with 7. Replace line with the line number, which is in the range of 1 to 3 on an SRM-3T3/C
card.
-st The signaling transport mode applies only if you have
selected byte-synchronous tributary mapping (-tm 2).
Replace SignallingTranportMode with either a 2 to specify
transfer mode, or a 3 to specify clear mode.
With transfer mode, the framing bit is transferred to the VT
header.
With clear mode, the signaling bit is transferred to the VT
header.
-tg The tributary grouping type applies to SDH. Replace
TributaryGroupingType with a 2 to specify AU3, or a 3 to
specify AU4.
