Federal Communications Commission Part 68
This equipment complies with Part 68 of the FCC rules and the
requirements adopted by the ACTA. On the back of the 800 Series printed
circuit board is a label that contains, among other information, a product
identifier in the format US:AAAEQ##TXXXX. If requested, this number
must be provided to the telephone company.
A plug and jack used to connect this equipment to the premises wiring
and telephone network must comply with the applicable FCC Part 68
rules and requirements adopted by the ACTA.
The REN is used to determine the number of devices that may be
connected to a telephone line. Excessive RENs on a telephone line may
result in the devices not ringing in response to an incoming call. In most
but not all areas, the sum of RENs should not exceed five (5.0). To be
certain of the number of devices that may be connected to a line, as
determined by the total RENs, contact the local telephone company. For
products approved after July 23, 2001, the REN is part of the product
identifier that has the format US:AAAEQ##TXXXX. The digits
represented by ## are the REN without a decimal point (e.g., 03 is a REN
of 0.3).
If your 800 Series card causes harm to the telephone network, the
telephone company may notify you in advance that temporary
discontinuance of service may be required. But if advance notice is not
practical, the telephone company will notify you as soon as possible.
Also, you will be advised of your right to file a complaint with the FCC if
you believe it is necessary.

Chapter 1
Overview
The 800 Series cards are versatile devices used for connecting your phone
network to the PSTN (Public Switched Telephone Network) world. This
is accomplished through phone lines connected to the FXO (Foreign
Exchange Office) ports and phones connected via the FXS (Foreign
Exchange Station) ports. The cards allow Asterisk to connect to your
phone network, creating an office type telephony environment.
There are a variety of applications where the 800 Series cards (TDM800P
or AEX800) can prove useful. An example is provided in the following
figure.
Figure 1: Sample Card Application

Digium, Inc. Page 16
Chapter 1: Overview
Echo-Cancellation
Users connecting their 800 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 800 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 TDM800P and AEX800.
The VPMADT032 is designed to handle up to 128ms of echo cancellation
across all channels and provides a G.168 echo cancellation solution.

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. 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
architecture allows it to convert between a wide range of communications
protocols and media codecs.

Digium, Inc. Page 18
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

Chapter 2: Card Installation
Unpacking the Card
When you unpack your card, carefully inspect it for any damage that may
have occurred in shipment. If damage is suspected, file a claim with the
carrier and contact the reseller from which the card was purchased, or
contact Digium Technical Support at 1.256.428.6161. Keep the original
shipping container to use for future shipment or proof of damage during
shipment.
Note: Only qualified service personnel should install the card. Users
should not attempt to perform this function themselves. The installer
must ensure that the equipment is permanently connected equipment,
pluggable type B or connected to a socket-outlet that has been checked
to ensure that it is reliably earthed in accordance with the National
Electrical Code.
This card is intended for installation in a Restricted Access
Location (RAL) only.
