Dial Access
This field controls whether users can route outgoing calls through an outgoing or 
two-way trunk group by dialing its trunk access code. Allowing dial access does 
not interfere with the operation of AAR/ARS.
!SECURITY ALERT:
Calls dialed with a trunk access code over WATS trunks bypass 
AAR/ARS and aren’t restricted by facility restriction levels. For 
security, you may want...

Use this field if you want attendants to control access to outgoing and two-way 
trunk groups during periods of high use. When the threshold is reached and the 
warning lamp for that trunk group lights, the attendant can activate trunk group 
control: internal callers who dial out using a trunk access code will be connected 
to the attendant, and the attendant can...

Queue Length
Outgoing calls can wait in a queue, in the order in which they were made, when all 
trunks in a trunk group are busy. If you enter 0, callers receive a busy signal when 
no trunks are available. If you enter a higher number, a caller hears confirmation 
tone when no trunk is available for the outgoing call. The caller can then hang up 
and wait: when a trunk becomes...

Trunk Flash
Some central offices allows users to activate special services (call waiting or 
3-way conferencing, for example) by flashing the switch hook on their phone. If 
an outside caller does this while they’re on a call with one of your users, your 
switch may interpret the flash as a disconnect signal and end the call. Use this 
field to prevent such accidental disconnections....

used in DEFINITY ECS, compares the line coding of available digital facilities 
and selects appropriate routes for voice and data calls. The Information Transfer 
Capability field appears when the Comm Type field is data, avd, or rbavd and the 
BCC field is not 0.

auto/autoThe term before the slash tells the switch how and when it will 
receive incoming digits. The term after the slash tells the 
switch how and when it should send outgoing digits.
nauto — Used for immediate connection to a single preset 
destination (incoming CO trunks, for example). No digits 
are sent, because all calls terminate at the same place.

group. The setting of the Trunk Signaling Type field can affect the entries allowed 
in this field. In addition, settings may differ for incoming and outgoing trunks.
