Outgoing Dial Guard (msec)

Valid Entry

Usage

100 to 25500 in increments of 100

The minimum interval between seizure acknowledgment of a trunk and the outpulsing of digits. For trunks that do not provide seizure acknowledgment, the timer specifies the minimum time between seizure and the outpulsing of digits. Any digit the caller dials after lifting the receiver, but before the timer expires, is not outpulsed until the timer expires.

This field cannot be blank.

Outgoing Disconnect (msec)

Valid Entry

Usage

50 to 2550 in increments of 10

The minimum valid duration of a disconnect signal for an outgoing call. Communication Manager does not recognize shorter disconnect signals. This timer begins timing when a disconnect signal is detected on an outgoing call and resets when the signal is no longer detected. If the timer expires, the trunk drops.

This field cannot be blank. For Brazil pulsed E&M signaling, use 600.

Outgoing Disconnect Send (msec)

Available only for two-way or outgoing trunk groups when the Trunk Type is dis. Only TN2140 ports receive this timer.

Valid Entry

Usage

100 to 9900 in increments of 100

The duration of the forward release signal the server running Communication Manager sends at the end of outgoing calls.

Outgoing End of Dial (sec)

Available for outgoing or two-way trunk groups when the network does not provide answer supervision.

Valid Entry

Usage

1 to 254 in increments of 1

The maximum time Communication Manager waits to receive answer supervision for outgoing calls on the ports controlled by firmware timers. Controls firmware answer supervision timers on media module that have them.

During a cut-through operation, timing begins after Communication Manager sends each outgoing digit and ceases when answer supervision is received. If the timer expires, Communication Manager acts as if it has received answer supervision. On senderized operation, the timer begins after the switch sends the last digit collected. The timer ceases when answer supervision is received. If the timer expires, Communication Manager acts as if it has received answer supervision.

For Brazil pulsed E&M signaling, use 40.

Valid Entry

Usage

100 to 25500 in increments of 100

The minimum interval that must elapse between a trunk’s release from an outgoing call and its seizure for another outgoing call. This delay gives the far-end time to release all equipment after the outgoing trunk is released. This field cannot be blank.
