60
Wait for alerting guard timer. This timer starts when a call is initiated
and stops when an alerting indication is received. On timer expiry it
releases the call using internal token 129.
300
Wait for answer guard timer. This timer starts when alerting is
received for a call and stops when an answer indication is received.
On timer expiry it report an event to the alarm log and releases the
call using internal token 130.
This timer can be selected using the TANS timer on an outgoing
route basis.
120
Wait for release complete guard timer. This timer starts when either
a release is received for a call or when a release is generated. It is
stopped when call control receives a release complete indication. On
timer expiry it re-attempts a release using internal token 134 and
restarts the timer. After 5 attempts if no release complete is received
it resets the circuit.
300
Wait for resume guard timer. This timer starts when a suspend
indication is received and stops when a resume indication is
received. On timer expiry it releases the call using internal token 132.
7
Wait for board response guard timer. This timer starts when internal
messages are sent to a signalling board and stopped when an
acknowledgement is received. On timer expiry it reports and error. If
the internal message sent to a board related to setting up a speech
path for a call then the call is released using internal token 135.
5
Campon busy circuit timer. If no circuit is available on the outgoing
side the outgoing circuit is 'camped on' and the timer started. If the
outgoing circuit becomes idle the timer is stopped and the held call is
routed over the outgoing circuit. On timer expiry the call is released
using internal token 133.
3
MML wait for maintenance confirmation timer. The timer is started
when a MML maintenance request is performed. It is stopped when
a confirmation from the remote site to the maintenance request is
received. On timer expiry a confirmation to the request is internally
generated allowing further MML commands to be entered.
7
Wait for signalling failure stabilisation timer. This timer is started
when signalling loss is detected. It is stopped when a signalling
resume is received. On timer expiry all circuits using that signalling
link are reset.
60
Wait for stop digit timer. The timer is started when an initial address
message without a stop 'f' digit is received by the converter. It is
stopped when a subsequent address message is received with a
stop digit or a backward address complete message is received. If a
subsequent address message is received which does not contain
digits then the timer is stopped and started again. On timer expiry
stop digit is generated in a subsequent address message.
10
User service control request timer. This timer is started when the
converter requests that for a call the user service control application
on a remote system perform a call processing action. It is stopped
when the user service control application responds to the request.
On timer expiry the call is released.
