Defining Operating Parameters

5-47

Automatic Disconnect

This parameter specifies the conditions that cause the DAP to automatically disconnect a

dial backup connection. You can select from the following options:

• No DTR - the DAP disconnects the call after the DTR signal from the dial

backup port's DTE goes Off.

• None - the DAP disconnects the call when multiport framing is lost for longer

than 90 seconds.

Note: A network disconnect signal overrides the Automatic Disconnect parameter

setting.

Retry Attempts

This parameter specifies the maximum number of times that the DAP will redial a call if

the previous attempt is unsuccessful. The Excalibur Multirate DAP allows you to store

six telephone numbers: one permanent, four alternate, and one temporary. The possible

settings for each phone number range from 0 (retries disabled) through 9. If this

parameter is set to 0 and an automatic dial attempt fails, a Return to Normal (RTN)

function must be performed from the front panel of the local unit before the unit will

automatically dial again. (See "RTN Function" in Chapter 7 for instructions.) From the

CMS system console, a Re-enable Auto Retries, under the Excalibur Dial Restoral

function, must be performed before the unit will automatically dial again.

Dedicated Line Test

This parameter specifies whether the DAP continuously monitors the dedicated line while

it is operating over the dial backup line. When the Network parameter is set to point-to-

point, the DAP monitors for end-to-end dedicated line connectivity. If there is end-to-

end connectivity for the specified time, the DAP disconnects the dial backup line and

returns data transmission to the dedicated line. When the Network parameter is set to

multipoint, the DAP monitors the same conditions that is uses for DDS Up in the Line

Statistics submenu for the selected time interval. The DAP does NOT monitor for the

presence of multiport framing. If the DDS network is up for the specified time, the DAP

disconnects the dial backup line and returns data transmission to the dedicated line.

Note: This parameter must be set to None when the service is set for LADC or LDM

and the clocking is set to External.
