■
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.
6. Test the voice quality on a telephone connected through the TN464GP or
TN2464BP circuit packs and known to have echo to see if the echo was
eliminated.
7. If the echo still exists, set the
EC Configuration:
field to 1, 2, or 3, then
test the voice quality. These settings provide help for the following
scenarios:
■
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.
8. If after trying all these settings, the echo still exists, contact technical
support. Refer to
Where To Call for Technical Support.

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.
