Type: Unsigned32

Description: This attribute specifies the waiting time for a silent B-Channel (no active VCs associated with the FrUni) to be disconnected and made available. Default is 60 seconds. 0 means t320 will never timeout.

What is mscFrUniIsdnT320?

This object sets, in seconds, how long a silent B-Channel with no active virtual circuits is left idle before the system disconnects it and frees it for other use. An admin tunes this timer to control how quickly idle ISDN B-Channels are reclaimed for other calls, with a value of 0 meaning the channel never times out. For example, leaving this at the default of 60 disconnects an unused B-Channel after one minute of no active VC traffic.
