Chapter 5 Preparing SRM Cards for Communications
Establishing Redundancy Between SONET/SDH Lines with APS
The following example configures 1+1 APS line redundancy for the lower bay of a
MGX 8850 (PXM1E/PXM45) switch:
mgx8850b.1.PXM.a > addapsln 31.1.1 32.1.1 1
Step 6 Enter the cnfapsln command to configure the APS line, as follows:
mgx8850b.1.PXM.a > cnfapsln -w <workingline> -sf <SignalFaultBER> -sd <SignalDegradeBER>
-wtr <Wait To Restore> -dr <direction> -rv <revertive> -proto <protocol>
Table 5-5 describes the command parameters.
4 Selects 1+1 Y-cable signaling without K1 and K2.
Note This option is not supported in this release.
5 Selects 1+1 straight cable signaling without K1 and K2.
