Chapter 12: Trunk Configuration
142 MAXCS ACC 6.7.1 Administration Manual
• 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.
• Direction – The trunk direction can be Outgoing only, Incoming only, Both Out-
going and Incoming, Paging, or E911. The Both option is the system default.
Important:If a trunk is in the hunt group of your company main number and you
configure this trunk as an "Outgoing" trunk, the incoming call will be
rejected by the system. To avoid this mistake, make sure you check
with your carrier to verify the hunting number before you configure a
trunk to Outgoing.
Paging – This configuration is for an overhead paging equipment and requires a
Loop Start trunk port. The paging equipment will provide loop current to the trunk
port.
When this option is selected, you can assign an ID in the list. The range of paging
IDs are from 00 to 99, which allows MAXCS to be connected to up to 100 paging
systems through trunks for multi-zone paging applications.
To activate a trunk paging port, dial #45 and the ID number. For example, a user
dials #4508 to connect to a paging system through the trunk with paging ID of 08.
The Trunk Paging option and the Overhead Paging option (in “Audio Peripheral
Configuration” on page 60) are different and independent of one another. The
Overhead Paging option is to set up the Audio Out port on the telephony board
and uses #44 to activate.
The E911 option is exclusively for an analog Centralized Automatic Message Ac-
counting (CAMA) trunk connecting to a Triton analog trunk board. CAMA trunk is
a special type of trunk from your carrier for E911 service. When an analog trunk
port is assigned as an E911 CAMA trunk, the system will send the station identi
-
fication number, defined in the extension configuration E911 CID field, to the
PSAP via multi-frequency signaling. The E911 CID is needed to:
• Allow PSAP to identify the caller's information and exact location by matching
the Automatic Location Identifier database in PSAP.
• Have the callback number in case the call is disconnected.
Note: Do not select the E911 option for a T1-CAS or PRI trunk. T1-CAS cannot
transmit the ID. PRI trunk will transmit calling party's ID automatically.
When the E911 option is checked, this trunk will no longer receive inbound
calls, and only 911 calls will go out through this trunk.
Each state may have different E911 regulations and requirements. Check
with the local authority to understand what is required by law.
• Phone Number – If this trunk is an analog or T1-CAS trunk, this field is used for
labeling purposes only. Enter the number without area code in this field. If this trunk
is a PRI trunk, the system will output this number to the carrier as the calling party
CallerID.
PRI trunk transmitting caller ID rules:
1. If extension has Transmitted CID configured, this number will be transmitted
first. If not configured, go to next.
2. If extension has DID Number configured, the 10-digit DID number will be
transmitted. If not configured, go to next.
