3.16 Flash - Analog Port (SLT) Flash Recognition

Flash is the momentary operation of the hook-switch at the analog device, which can be

placed in a status of transfer awaiting further instructions from the user.

3.19 Line Group Assignment

System assigns each PSTN/IP line to a specific Line Group. Each line can be assigned

If setting some PSTN lines and some IP lines into the same Line Group, the line access

depends on the access priority.
