Overview
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 Associated
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 series 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 near-end echo to the calling party. Elimination of this echo
is the responsibility of echo cancellation.
The TE120 series cards, unless otherwise equipped, utilize Asterisk to
perform software-based echo cancellation. Asterisk maintains a number
of open source echo cancelers. These open source echo cancelers provide
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 the TE121 andTE122 cards; it
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 designed to handle up to 128ms of echo cancellation
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 operate 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:

Chapter 1: Overview
What is Asterisk®?
Asterisk is the world’s leading open source telephony engine and tool kit.
Offering flexibility unheard of in the world of proprietary
communications, Asterisk empowers developers and integrators to create
advanced communication solutions...for free. Asterisk® is released as
open source under the GNU General Public License (GPL), and it is
available for download free of charge. Asterisk® is the most popular open
source software available, with the Asterisk Community being the top
influencer in VoIP.
Asterisk as a Switch (PBX)
Asterisk can be configured as the core of an IP or hybrid PBX, switching
calls, managing routes, enabling features, and connecting callers with the
outside world over IP, analog (POTS), and digital (T1/E1) connections.
Asterisk runs on a wide variety of operating systems including Linux,
Mac OS X, OpenBSD, FreeBSD and Sun Solaris and provides all of the
features you would expect from a PBX including many advanced features
that are often associated with high end (and high cost) proprietary PBXs.
Asterisk's architecture is designed for maximum flexibility and supports
Voice over IP in many protocols, and can interoperate with almost all
standards-based telephony equipment using relatively inexpensive
hardware.
Asterisk as a Gateway
It can also be built out as the heart of a media gateway, bridging the
legacy PSTN to the expanding world of IP telephony. Asterisk’s modular
architecture allows it to convert between a wide range of communications
protocols and media codecs.

Release 2.2 Digium, Inc. Page 19
Chapter 1: Overview
Asterisk as a Feature/Media Server
Need an IVR? Asterisk’s got you covered. How about a conference
bridge? Yep. It’s in there. What about an automated attendant? Asterisk
does that too. How about a replacement for your aging legacy voicemail
system? Can do. Unified messaging? No problem. Need a telephony
interface for your web site? Ok.
Asterisk in the Call Center
Asterisk has been adopted by call centers around the world based on its
flexibility. Call center and contact center developers have built complete
ACD systems based on Asterisk. Asterisk has also added new life to
existing call center solutions by adding remote IP agent capabilities,
advanced skills-based routing, predictive and bulk dialing, and more.
Asterisk in the Network
Internet Telephony Service Providers (ITSPs), competitive local
exchange carriers (CLECS) and even first-tier incumbents have
discovered the power of open source communications with Asterisk.
Feature servers, hosted services clusters, voicemail systems, pre-paid
calling solutions, all based on Asterisk have helped reduce costs and
enabled flexibility.
Asterisk Everywhere
Asterisk has become the basis for thousands of communications
solutions. If you need to communicate, Asterisk is your answer. For more
