Description: Used by SDM-9400 and V410 VFC03 cards and by the SDM-9350 and V352 voice ports for versions 7.1.0 and higher. Used only for DVC cards for versions 7.0.3 and lower. See also ifvceAnalogLinkDwnBusy for versions 7.0.3 and lower.

What is ifvceLinkDwnBusy?

This read-write setting, applicable to SDM-9400 and V410 VFC03 cards and to SDM-9350/V352 ports on firmware 7.1.0 and higher, and to all DVC cards on 7.0.3 and lower, decides whether the port reports busy or does something else (no/yes/broadcast) when the underlying WAN link goes down. It lets an administrator control the busy-signal behavior presented to attached telephone equipment during a link outage, rather than leaving the line silently dead. For example, setting this object to yes(2) makes the port play a busy tone to the attached phone as soon as the WAN link fails, alerting the user immediately that calls cannot go through.
