[Raju]
Right. There are several reasons why a termination can be out of service(OOS).
Take a look at "H.248.8 : Gateway control protocol: Error code and service change reason description"
http://www.itu.int/rec/T-REC-H.248.8-200708-I/en
Following are some of the relevant ones:
904 Termination malfunctioning
905 Termination taken out of service
906 Loss of lower layer connectivity (e.g. downstream sync)
907 Transmission Failure
MGC can put a termination OOS and bring it back INS later.
Please see "F.4.1.2 ServiceChange Method Behaviour on Physical Terminations" of:
http://www.itu.int/rec/T-REC-H.248.1-200509-I/en
However, if the termination is OOS due to 904/906/907 reason codes then MGC
obviously can't bring it INS.
