Setting General Trunk Attributes
• Area Code - The local area code for each trunk. Enter a three-digit
area code. If left blank, the trunk assumes the home area code defined
in the General tab of the System Configuration window. This
configuration is for each trunk in the system and will negatively affect
features such as Zoomerang if the area code is not configured
properly. This is not available for a DID trunk.
• Direction - The trunk direction can be Outgoing only, Incoming only,
Both Outgoing and Incoming, or for Paging. Outgoing and Both are
not available on an analog Quantum DID trunk, which is an Incoming
trunk. The Both option is the system default.
Paging is only available for analog (CO) trunks and is used for paging
or broadcasting purposes. This option enables a third party paging
device directly to the trunk port.
When this option is selected, the system assigns a default unused
paging ID. You can assign a different ID in the drop-down list. The
range of paging IDs are from 00 to 99, which allows AltiServ to be
connected to up to 100 paging systems through trunks for multi-zone
paging applications. If the manually selected paging ID is used by
another trunk, the current paging ID is not changed.
The trunk paging is accessed using the Overhead Paging by Trunk
(# 45 Feature Code). For example, a user dials '#4508' to connect to a
paging system through the trunk with paging ID of 08.
The Overhead paging feature requires paging equipment to provide
loop start CO trunk characteristics. This option is not supported on
ground start trunks.
The Paging option and the Overhead Paging option (in "Audio
Peripheral Configuration" on page 5-25) are different and independent
of one another. The Overhead Paging option is to set up the audio out
port of the Quantum board for use with the #44 overhead option built
into the system.
The E-911 feature allows a caller to dial 911 without dialing a trunk access
code and allows the 911 caller to be located in a PBX system.
trunk can be selected and reserved for E-911 calls but the customer
must make sure the carrier provides E-911 service in the PRI span. If
CAMA trunks (trunks "dedicated" for Enhanced 911 usage) are
available from the carrier, Triton analog and Quantum analog trunks
can be configured as CAMA trunks to support E-911.
Note: E-911 is not supported by T1 protocol
