436 China - Supervised Analog Lines
line is reverted to normal polarity when the terminal device completes
the transfer and drops out or when the last of either the held party or the
consultation party disconnects.
Conference
If a terminal device answers an incoming call and then initiates a conference,
no battery reversal answer supervision signal is extended to the terminal
device when new parties of the conference answer. However, a hook flash
disconnect supervision signal is extended to the terminal device when the
last party in the conference disconnects.
If a terminal device initiates a conference, battery reversal answer
supervision is extended to the terminal device when the first party answers.
No polarity change is made when additional parties are added to the
conference. The polarity is reverted to normal when the terminal device
disconnects or when the last party in the conference disconnects.
Multi-Party Operations
As in the cases with Call Transfer and Conference, the call type of the first
active call determines whether battery reversal or hook flash supervision
applies. Also, supervision signaling is not supported for the second call.
A disconnect supervision signal is extended only when the last party
disconnects.
