Chapter 1 Overview

The Digium TE800 Series is a T1/E1/J1 capable car d serie s created for
voice. They support industry standard protocols, including Robbed Bit
Signaling (also known as CAS or Channel Associate d Signaling), CCS
(Common Channel Signaling), E&M, and Primary Rate IS DN (PRI).
They are also capable of DACSing channels from one span to another.
The TE800 Series cards are ideal for connecting phones to a channel
bank, connecting to T1/E1 switches, or connecting to a legacy PBX. The
Y-adapter dongle that Digium engineered for use with the Digium TE800
Series allows twice the amount of spans to fit in a single PC slot, taking
up less space to allow for more peripher al s. Des igned to be fully
compatible with existing sof tware applications and integrate fully with
the Asterisk platfor m, th e TE800 Series cards allow many advanced call
features.

This manual is for use with the TE820/TE820B PCI Express car d. The se
are identified colle ctively as the TE800 Series cards throughout this
manual.

The TE800 Series cards can be used to connect your Asterisk machine to
the PSTN world, your channel bank, or even another PBX. This is
accomplished via a T1/E1 interface. The cards allow Asterisk software to

Echo-Cancellation

Chapter 1: Overview

Users connecting their TE800 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 ne ar-end echo to the calling party. Elimination of this echo
is the responsibility of ec ho cancellation.

The TE800 Series cards, unless other wise equipped, utilize Asterisk to
perform software-based echo cancellation. Asterisk mainta ins a number
of open source echo c ancelers. These open sou rce echo cancelers provide
a moderate level of echo cancellation, but are not capabl e of dealing with
higher levels of, or more advanced, echoes.

Digium recommends that those users concerned about echo cancellation
purchase the VPMOCT256 hardware echo cancellation module. The
VPMOCT256 may be combined with any of the TE800 Series cards.

The VPMOCT256 is designed t o handle up to 128ms of echo ca ncell ation
across all channels and provides a G.168 compliant echo cancellation
solution.

If equipped and not explicitly disabled in chan_dahdi.conf, th e
VPMOCT256 will automatically oper ate and cancel all network echo
within its tail range (1024 ta ps).

Chapter 1: Overview

What is Asterisk®?

Asterisk is th e world’ s leading open source telephony engine and tool kit.
Offering fle xibility 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), a nd it is available
for download free of charge. Asterisk is the most popular open source
telephony software available, with the Aste risk Community being the top
influencer in VoIP.

Asterisk as a Phone Switch (PBX)

Asterisk can be configured as th e 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/J1/BRI)
connections.

Asterisk runs on a wide variety of opera ting systems including Linux,
Mac OS X, OpenBSD, FreeBSD, and Sun Solaris. It provides all of the
features you would exp ect from a PBX inclu ding many advanced f eatu res
that are often associate d with high end (and high cost) proprietary PBXs.
Asterisk's archi tecture is designed for maximum flexibility and supports
Voice over IP in many protocols, and can interoperate with almost all
standards-base d 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

Digium, Inc. Page 18

Chapter 1: Overview

architecture a llows it to co nvert betwee n a wide ran ge of communicat ions
protocols and media codecs.

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 autom ated attendant? Asterisk
does that too. How about a replacement for your agi ng legacy voicemail
system? Can do. Unified messaging? No problem. Need a telephony
interface for your web site? Okay.

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 Ca rri ers (C LEC s ) an d eve n first -t ier incu m b en ts hav e
discovered the power of open source communications with Asterisk.
Feature servers, hosted services clusters, voicemail systems, and pre-paid
calling solution s, al l based on Asterisk have helped reduce costs and
enabled flexibility.
