Nota : To optimize management of this ARS table parameter, it is vital to have information about
the bandwidth available (reserved) for VoIP calls that is as precise as possible.
- Gateway Alive Status: this regularly updated read-only field indicates the status of the remote ga-
teway:
• Alive: remote gateway present
- Deactivated: remote gateway absent / out of service.
It can, however, turn out to be judicious to deactivate the mechanism if one is sure of network reliability,
in order to reduce the traffic.

network accesses:
