The Digium TE120 Series cards are T1/E1 capable cards that can handle
both voice and data. It supports industry standard protocols, including
Robbed Bit Signaling also known as CAS (Channel Associ ated
Signaling) and CCS (Common Channel Signaling), E&M (Digital
Emulation), Primary Rate ISDN (PRI), and several data modes (PPP,
HDLC, Cisco HDLC and frame relay). It is capable of running in E1, T1,
or J1 modes.

Designed to be fully compatible with existing software applications and
integrate fully with the Asterisk platform, the TE120 Series cards allow
many advanced call features.

Chapter 1: Overview

Echo-Cancellation

Users connecting their TE120 se ries cards to the PSTN or other devices
are likely to be placing calls that will result, at some point, in an
unbalanced 4-wire/2-wire hybrid. The result of this hybrid is the
reflection of a ne ar-end echo to the calling party. Elimination of this echo
is the responsibility of echo canc ellation.

The TE120 series cards, unless otherwise equipped, utilize Asterisk to
perform software-based echo cancellation. Asterisk maintains a number
of open source echo canc elers. The se open source echo ca ncelers pr ovide
a moderate level of echo cancellation, but are not capable of dealing with
higher levels of, or more advanced, echoes.

Digium recommends that those users concerned about echo cancellation
purchase the VPMADT032 hardware echo cancellation module. The
VPMADT032 may be combined with both t he TE121 and TE122 ca rds; i t
may not be combined with the TE120P card. The TE121 and TE122 are
offered bundled with the VPMADT032 as, respectively: TE121B,
TE122B.

The VPMADT032 is desi gned to h andle up to 128m s of e cho cance llati on
across all channels and provides a G.168 compliant and AT&T Labs
certified Toll-Quality echo cancellation solution.

If equipped and not explicitly disabled in zapata.conf, the VPMADT032
will automatically ope rate and cancel all network echo within its tail
range (1024 taps). Users of TE120P cards, which do not maintain the
capability to support the VPMADT032, may purchase Digium's
commercial HPEC software:
