This feature programs the maximum length of a call if no other
disconnect features are used (1-15 minutes, in 1 minute
increments). The call duration timer begins when the emergency
telephone goes off-hook. The emergency telephone automatically
disconnects after the programmed time-out period elapses.
The user can immediately press the
EMERGENCY
button to
reconnect the auto-dial number. This feature helps prevent non-
emergency calls from tying up emergency lines for long lengths
of time.
For Example
: To make the maximum call length two minutes,
enter
# 1 2 0 2
. To make the maximum call length infinite, such
as no automatic disconnect, enter
# 1 2 0 0
.
