This is a global setting that affects all of the PVCs in the IQ 710 DLCI table (under
N
ETWORK
PVC
O
PTIONS
). A PVC is advertised as Inactive by the frame switch in the CO when there is a problem
at the remote end of the frame circuit. With this option enabled, the IQ 710 unit will attempt to
establish a dial backup call with the remote unit when its corresponding DLCI is advertised as
Inactive. This parameter must be enabled for the group parameter to function.
