Trunk type
Trunk/line data varies with the type of trunk module, the configuration, and what
line you select. For example, you can configure the EE-DTM as PRI or T1.
You can program the following trunk types:
Hardware Unit
EE-DTM
EE-CTM (North America)
EE-BRIM S/T
Note: The Fixed data channel trunk type is required if you want to use the soft
router feature in Enterprise Edge. You must first install an EE-DTM and
configure it as Module type, T1 (see
configure the Trunk type as Fixed data channel. You can now configure
Module 08 as a Data module (see
Voice over IP trunk considerations
For IP functionality with Enterprise Edge VoIP Gateway, the trunk type is VoIP.
Enterprise Edge VoIP Gateway routes voice traffic over private Internet Protocol
(IP) networks to link multiple sites together using an existing corporate data
network. Lines 001 to 014 are reserved for IP functionality. The number of lines
available for use is a function of software key codes and currently eight of the 14
lines are available for IP functionality.
Note: VoIP trunks should not be accessed through Line appearances as the user
will not receive dial tone.
VoIP trunks should be configured to use a discrete line pool (Pool A to O). Do not
mix other trunk types on the same line pool. You can configure your IP trunks to
use the fallback feature.The use of Line pool codes is not recommended as you will
not be able to configure for fallback. The quality of the IP trunk connection is
assessed during initial call setup, and if the quality is outside the configured
threshold, Enterprise Edge will try to find an alternate route to complete the call
(fallback) based on the programming definitions in the routing table. If you do not
configure your network for fallback and the call quality is below threshold, the IP
call will fail. For an example of a network configuration that supports fallback, see

Enable modules
If you disabled any Trunk Modules prior to perform programming, enable
them now, or your system will not function properly. See
