Answer Supervision Timeout
If the Receive Answer Supervision field is n, use this field to set the answer
supervision timer for outgoing and two-way trunks. During a cut-through
operation, timing begins after each outgoing digit is sent by the switch and timing
ceases after the far-end sends answer supervision. If the timer expires, the switch
acts as if it had received answer supervision. On senderized operation, the timer
begins after the last digit collected is sent by the switch.
NOTE:
This field’s setting does not override answer supervision sent from the
network or from DS1 port circuit timers. To control answer supervision sent
by DS1 firmware, set the Outgoing End of Dial (sec) field on the
Administrable Timers page of the trunk group screen.
Auth Code
This field affects the level of security for tandemed outgoing calls at your switch.
This field appears if the Direction field is incoming or two-way, and it can only be
y if the Authorization Codes field is y on the System-Parameters
Customer-Options screen.
Auto Guard
This field appears if the Group Type field is co or fx. This field controls ports only
on TN438B, TN465B, and TN2147 circuit packs. TN438B ports have hardware
support for detecting a defective trunk. TN465B and TN2147 ports consider a
trunk defective if no dial tone is detected on an outgoing call, and the Outpulse
Without Tone field is
n on the Feature-Related System Parameters screen.

to 250 Enter the number of seconds you want the switch to wait
before it acts as though answer supervision has been received
from the far-end. Set this field to

Supervision is
y.
Valid entries Usage
y/n
Enter y to require callers to enter an authorization code in
order to tandem a call through an AAR or ARS route pattern.
The code will be required even if the facility restriction level
of the incoming trunk group is normally sufficient to send the
call out over the route pattern.
Valid entries Usage
y/n
Enter y to prevent repeated seizures of a defective trunk. The
switch will do a maintenance busy-out on these trunks.
