Requirements
Each Central Office (CO), Foreign Exchange (FX), Personal Central Office Line
(PCOL), or Wide Area Telecommunications Service (WATS) trunk connects to 1
port of either an 8-port TN747B or to 1 of several CO trunk circuit packs.
Installation
1. Install a TN747B or a CO Trunk circuit pack in the assigned carrier slot (if
an additional circuit pack is required).
2. Administer the forms listed under CO, FX, WATS, or PCOL Trunk Group in
Administrator's Guide for Avaya Communication Manager.
3. Determine the port assignment of the trunk from the Trunk Group form.
EXAMPLE:

Keep the default setting for the EC Configuration: field of 4.
This setting minimizes extremely strong echo, very hot signals, or
excessive clipping or breakup of speech from a distant party. It
reduces speech clipping but may allow slight residual echo or more
background noise.
Setting 1 rapidly minimizes echo when first detected, regardless of
the loudness of the talker's voice. Settings 1 and 4 have the same
EC settings except that Setting 1 introduces 6 dB of loss.
Setting 2 minimizes speech clipping, but it takes a fraction of a
second longer for the echo to fade.
Setting 3 eliminates speech clipping, but a strong echo may take 2
or 3 seconds to fade.
