Make Busy/Remove Make Busy

The Make Busy function forces the modem off-hook so it cannot answer a call. This is often used with PBX systems to permit the busy out of a PBX port for rotary or hunt groups.

WARNING

Service Line/Disconnect Service Line

The Service Line function allows you to switch a specific Model 3811 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 3811 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:

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 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.
