If actions a or b fail to correct this problem, check to see if the LAN adapter is properly
installed in the CyberSWITCH. Refer to the

2.
For each basic rate or primary rate line configured and attached to the CyberSWITCH, the
following line initialization message should be displayed among the system messages:
Data Link up: <slot #> <port #> <ces>
If this message is displayed for each configured line, then the WAN lines are available for use.
Notes: Depending on the resource switch type, the system will delay up to 2 minutes before
attempting to bring up the data links.
Other messages may also be displayed with the line initialization messages.
3.
If the WAN lines are NOT available, the system may display one of the following messages on
the LCD:
Line (slot #, port #) down
Out Svc 1 (slot #, port #)
Out Svc (2, 3, 4, or 5) (slot #, port #)
To correct the problem, try the following:
Line (slot #, port #) down:
