Service Line/Disconnect Service Line

The Service Line function allows you to switch a specific Model 3911 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, 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 3911 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 3911 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:

Control:

Service_Line

F1 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 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 DiscServiceLine appears.

Select DiscServiceLine. The call and service line disconnect and the message Command

Complete appears on the LCD.
