MIDAS 4.2 Basic Configuration, Rev. 1
Setup and Operation 2–57
Calls that retry: Calls that don't retry:
Permanent Remote-initiated calls
Scheduled RTS-initiated calls
(although the node will automatically re-issue the request,
giving the effect of retry)
Retry only applies to abnormal termination and startup failures. Normal
termination will always end a call without retry, and in the case of a permanent
call, a normal termination will set the circuit to disabled.
The permanent call option for the DC command at the node's user port creates
a true permanent call, which will retry. If the call is terminated later from the
user port via the TE command, this will disable the permanent circuit, since it
will be a normal termination.
Note: If activation type is RTS and CiM modems are used, the From/A
side will have to configure the RTS Teardown Delay.
The Tear Down Time Out field is displayed in the Communications Setting
window ONLY when a Comtech IP Modem (CiM) is s elected. This field is
provided to keep a circuit from being inactivated prematurely due to the bursty
nature of the IP traffic. It is used only for RTS circuits to define how long after
the last packet was routed that a circuit connection should remain active. Valid
entries include any number of seconds from 1 to 65,535 (more than 18 hours).
Note: These two fields do not display simultaneously as each is specific to
a modem type.
