Excalibur ISX 5312/5314 T-1 Multiplexer Installation and Operation

5-46

The following example shows you the steps to follow to change the Remote T7
parameter from 8 Kbps mode to DS0 mode.  For this example, the following
assumptions are made:

Remote T7 and 8 Kbps mode are enabled for both DTE 2 and DTE 4

You want to change DTE 2 to DS0 mode

Follow these steps:

1. Disable the LRC alarm for DTE 4, as described on the previous page.

2. Set DTE 2 to Remote T7 via DS0.

3. Set DTE 4 to 8 Kbps mode.

4. Enable the LRC alarm for DTE 4.

If LRC is enabled and you attempt to disable a DS0 channel used for remote T7 transport
(

), the screen displays the message:

Trigger LRC

.

Connect Timer

The Connect Timer parameter allows you to specify the amount of time that user-
specified DS1 line alarm conditions can be active before the ISX 5312/5314
automatically dials the backup device connected to DTE 2.  The available options are

5s

15s

30s

60s

 (seconds), and 

AAns

 (Auto-Answer).  When the Auto-Answer option is

selected, the ISX 5312/5314 only answers incoming calls from the device connected to
DTE 2.  It does not initiate dial backup calls, and it does not terminate dial backup
connections.

Disconnect Timer

The Disconnect Timer parameter allows you to specify the amount of time that the DS1
line can be in a good state before the ISX 5312/5314 automatically terminates the dial
backup connection and returns communication to the DS1 line via DTE 1.  This
parameter is non-functional when the Connect Timer parameter is set to Auto-Answer or
the Revert parameter is set to Disabled.  The available options are 

5s
