Service Line/Disconnect Service Line
The Service Line function allows you to switch a
specific Model 381
1 installed in a COMSPHERE
3000 Series Carrier from normal dial or leased-line
operation to service-line operation. This switch only
places the modem on the service line. For a connection to
be established, you must still use the normal dialing
methods as described in
Chapter 5,
Call Setup Branch
.
A service line is an extra dial line connected to a
COMSPHERE 3000 Series Carrier. This line is normally
shared by up to eight Model 381
1 modems installed in
either Slots 1–8 or Slots 9–16. However
, by daisy
chaining the service-line connector of one Network
Interface Module (NIM) to the service line of another
NIM installed in the same carrier, you can permit all
16 modems to share one service line. The service line can
also be extended to other carriers in a cabinet. For more
information regarding daisy chaining of modems to the
service line, refer to the COMSPHERE 3000 Series
Carrier, Installation Manual.
A service line is ideal for a dial backup of Model 3811
modems operating on leased lines. Remember that a
service line can back up only one failed leased line at a
time.
To enable service line from the Control branch, make
the following selections:
F1
Control :
Service_Line
F2
F3
Press the key until Service_Line appears. Select
Service_Line to switch the modem from its normal dial
line to the service line. Now
, when the modem places a
call, instead of using the dial or leased line, the call is
placed on the service line.
To disconnect the modem from the service line and
resume normal operation, press the
key once and the
key until Disc Serv Line appears.
Select Disc Serv Line. The call and service line
disconnect and the message
Command Complete
appears on the LCD.
