Managing Lines
Displaying the Configuration for a Single Line
To display the configuration of a single line on an AXSM card, enter the dspln command in the
following format:
dspln <-ds3|-e3|-sonet|-e1> <bay.line>
Replace <bay.line> with the number of the line you want to display.
Note To display a list of all line numbers on the card, enter the dsplns command.
In the following example, the user displays the configuration for the T3 (DS3) line 1.1:
M8850_LA.3.AXSM.a > dspln -ds3 1.1
Line Number : 1.1
Admin Status : Up Alarm Status : Clear
Line Type : ds3cbitadm Number of ports : 1
Line Coding : ds3B3ZS Number of partitions: 0
Line Length(meters) : 0 Number of SPVC : 0
OOFCriteria : 3Of8Bits Number of SPVP : 0
AIS c-Bits Check : Check Number of SVC : 0
Loopback : NoLoop
Xmt. Clock source : localTiming
Rcv FEAC Validation : 4 out of 5 FEAC codes
Xmt. Trace (E3 only):
M8850_LA.3.AXSM.a >
Bringing Down a Line
When a line is not working properly, it generates a line alarm. If you want to suppress the alarm and you
do not have time to correct the problem, you can bring down the line. Bringing down the line takes it out
of service, so no alarms are generated.
Tip You can reduce the level of an alarm on a failed line from major to minor by using the addlnloop
command to place the line in local loopback mode. This does not completely eliminate the alarm, but it
does reduce the severity and allow you to preserve the configured resources for that line.
To bring down a line, use the following procedure.
Step 1 Delete all connections that are associated with the line and paths ((dspcons and delcon commands).
Tip Connections are associated with ports (dspcons), and ports are associated with lines (dspports).
To determine which connections use a line, first determine which ports are configured for that
line.
Step 2 Delete all partitions that are associated with the port (delpart command).
Step 3 Delete all ports that are associated with the line (delport command).
Step 4 Delete any paths that are associated with the line (dnpath command), and unchannelize the line you
want to delete.
