For answer detection of analog trunks:
In case of answer supervision, when answer supervision is received, the system recognizes

In case of no answer supervision, after the inter digit timer has expired, the DTMF receiver
waits for the key to be pressed. Then the system recognizes the called party has answered.

An emergency call via analog trunk has no disconnect signal. If Program 14-02-18 is invalid
the call cannot be disconnected on the trunk side.
If the cable was disconnected while ringing, the ring does not restart once the cable is
reconnected.
In case of an emergency call trunk key status is red. It is also red while monitoring or
speaking.
An emergency call goes through even if no trunk key is assigned to the terminal.
If the cable is disconnected while ringing, an emergency call performance is same as off-
hook status. If the cable was not connected by ring timer, Program 20-01-19 is set to 1
provide an emergency call, set to 0 retry to ring the inspection terminal.
If internal paging access performed while ringing, continues remote inspection ringing.
In case of speaking status after monitor mode, monitored terminal key does not operate
except speaker key.
When disconnected from outside while monitoring, the line can not be released without
disconnecting the signal. It disconnects when the timer in Program 20-21-05 ends. A
disconnect also occurs while monitoring or speaking if the timer expires. To prevent a line
hold, a disconnect occurs if the timer in Program 20-21-05 ends while hearing an answer
message.
A maximum of six extensions can be set as Remote Inspection terminals.

inspection message or a destination message.
If the VRS message is not recorded, a tone is provided.

If Program 13-01-01 is set to ICM the system uses command Program14-06 to route the
emergency call.
