4.18.1 E&M Trunk Function
Description
There are two kinds of function for 2w or 4w way for E&M. It should have different signal line,
so consist of different h/w interface respectively.
Operation
2W method
Setting of external analogue port
1. Connect as the same port in both case for voice and signal port.(1:1).
2. Signal port must be crossed line.
3. Be used all ports chosen.
LOOP Example for self testing)
