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 in Chapter 10,
Branch.
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.
