Service Line/Disconnect Service Line
The Service Line function allows you to switch a
specific 381
1Plus modem 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 3811Plus
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.
