Bringing Up Lines
Installing an AUSM card can add up to 8 physical lines to your switch. You must bring up a line before
you can configure it or provision ATM services on the line.
Before a line is brought up, or after it is brought down, the switch does not monitor the line. Prior to
bringing up a line, the AUSM port status light for the line is unlit, and all line alarms are cleared.
When you bring up a line on an AUSM card, the switch starts monitoring the line. The AUSM card port
status light turns green when physical layer connectivity is established with a remote device. If a physical
layer communications problem occurs, the port status light turns red, and an alarm is reported.
To minimize the number of alarms reported and to reduce the frequency of failed port status lamps
Tip
(which display red), keep lines down until they are actually needed for communication.
To bring up an AUSM line on an MGX switch, perform the following steps:
Establish a configuration session using a user name with GROUP 1 privileges or higher.
Step 1
Select the AUSM card on which you want to bring up a line by issuing the cc command, as shown below:
Step 2
PXM1E_SJ.1.7.PXM.a > cc <slotnumber>
Replace the <slotnumber> parameter with the number of the slot in which the AUSM card is installed.
Step 3
To activate a line on the AUSM card, enter the addln command as shown below:
PXM1E_SJ.1.5.AUSMB8.a > addln <line>
Replace the <line> parameter with the number corresponding to the back card port to which the line is
connected.
