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
Num State Type Lpbk (meters) Criteria cBitsCheck
---- ----- ----------- ----------- -------- --------- ----------
7.1 Down dsx3CbitPar NoLoop 00000001 3Of8Bits Check
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.
