Range
0-255 Applicable to the System for Japan only. If the Call Delivered response
seconds (connect message) is not received before this timer expires, the System
disconnects the call.
1-255 Used for AT&T 5ESS custom switch type only. If the appropriate Call Pro-
seconds ceeding response (Alerting, Connect, or Disconnect) is not received
before this timer expires, the requesting system sends a Disconnect.
1-255 If the appropriate Connect Acknowledge is not received before this timer
seconds expires, the requesting system sends a Disconnect.
1-255 This timer is initiated when the data link layer is disconnected and is ter-
seconds minated when the data link is re-established. If the link is re-established
before this timer expires, the call is reconnected. If the timer expires
before the link is established, the call is released, and the B-channel is
cleared.
1-255 This timer is initiated when the data link layer fails and is terminated when
seconds the data link is re-established. If this timer expires before the link is re-
established, the system attempts to establish the link by sending a Data
Link Establish Request.
1-255 If the Disconnect or Release response is not received before this timer
seconds expires, the requesting system sends a Release.
1-65535 This timer controls how long the ISDN Data Link layer will remain idle
tenths before transmitting a Receive Ready (RR) Supervisory frame or an infor-
mation frame, once multi-frame operation has been established.
1-255 This timer determines the number of seconds that the system will wait
seconds between messages during the overlap receiving process. This timer is
started whenever the system receives a setup acknowledge message. It
is then restarted every time the system receives an information message
during the overlap receiving process. After the last information message
is received, the system has until this timer expires to send a call progress
message (for example, alerting, connected, etc.). If the system does not
send a call progress message or if the system does not receive an infor-
mation message before this timer expires, the call is cleared
1-255 This timer determines the number of seconds that the system will wait
seconds between messages during the overlap sending process. This timer is
started when the system receives the setup acknowledge message from
the network provider. It is then restarted every time the system sends an
information message during the overlap sending process. After the last
information message is sent, the system waits for a call progress mes-
sage (for example, alerting, connected, etc.) from the network provider. If
the system does not receive a call progress message or if the system
does not send an information message before this timer expires, the call
is cleared.
1-255 If the appropriate Release response (Release Complete) is not received
seconds before this timer expires, the requesting system sends another Release
or releases the B-channel and Call Reference value.
