Chapter 12: Trunk Configuration
140 MaxCS 7.5 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 prope
rly.
• Direction – The trunk direction can be Outgoing only, Incoming only, Both Outgoing and Incoming,
Paging , or E911. The Both option is the system default.
Note: 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 device 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 62) 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 Accounting (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 identification 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.
Please 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.
3. If PRI trunk channel has area code and caller ID configured, this number will be transmitted.
If not configured, go to next.
4. PRI will transmit the system home area code and main number defined in System
Configuration, General tab.
• Description – Descriptive information such as the company name for the assigned Phone Number, or
appropriate agency if this trunk provides 911 access.
• Trunk Dialing Scheme – Overlap or En-bloc dialing.
