Service Line/Disconnect Service Line
The Service Line/Disconnect Service Line is only available in Models 3921-B1-001 and
3021-B1-011.
The Service Line function allows you to switch a specific Model 3921Plus
installed in a
COMSPHERE 3000 Series Carrier from normal leased or dial 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 earlier in this chapter in the
Call Setup
Branch
section.
A service line is an extra dial line connected to a COMSPHERE 3000 Series Carrier
. This line is
normally shared by up to four Model 3921Plus multiport or eight singleport 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 eight multiport or sixteen singleport modems to share one service line. The service
line can also be extended to other carriers in a cabinet. For more information on daisy chaining
NIMs to the service line, refer to the
COMSPHERE 3000 Series Carrier
, Installation Manual.
A service line is ideal for a dial backup of Model 3921Plus
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:
