Overview
The Digium TE430 Series is a T1/E1 capable card series created for
voice. The cards in this series support industry standard protocols,
including Robbed Bit Signaling (also known as CAS or Channel
Associated Signaling), CCS (Common Channel Signaling), E&M, and
Primary Rate ISDN (PRI). The TE430 Series cards are capable of running
in E1, T1, or J1 modes. They are also capable of DACSing channels from
one span to another. The TE430 Series is ideal for connecting phones to a
channel bank, connecting to your T1/E1 switch, or connecting to a legacy
PBX.
This manual is for use with the TE435/TE435B PCI Express cards and the
TE436/TE436B PCI cards. These cards are identified collectively as the
TE430 Series cards throughout this manual.
Designed to be fully compatible with existing software applications and
integrate fully with the Asterisk platform, the TE430 Series cards allow
many advanced call features.

The TE430 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
connect to your network, creating a professional telephony environment.
Figure 2 on page 15 shows an example of the card’s primary application.

Chapter 1: Overview
Echo-Cancellation
Users connecting their TE430 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 TE430 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 VPM128 hardware echo cancellation module. The VPM128
may be combined with the TE435 (as TE435B) or TE436 (as TE436B)
cards.
The VPM128 is designed to handle up to 128ms of echo cancellation
across all channels and provides a G.168 compliant echo cancellation
solution.
If equipped and not explicitly disabled in chan_dahdi.conf, the VPM128
will automatically operate and cancel all network echo within its tail
range (1024 taps). Users may also 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
telephony software available, with the Asterisk Community being the top
influencer in VoIP.
Asterisk as a Phone 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/J1/BRI)
connections.
Asterisk runs on a wide variety of operating systems including Linux,
Mac OS X, OpenBSD, FreeBSD, and Sun Solaris. It 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

Digium, Inc. Page 19
Chapter 1: Overview
architecture allows it to convert between a wide range of communications
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 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? 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 Carriers (CLECs) and even first-tier incumbents have
discovered the power of open source communications with Asterisk.
Feature servers, hosted services clusters, voicemail systems, and pre-paid
calling solutions, all based on Asterisk have helped reduce costs and
enabled flexibility.
