This equipment complies with Part 68 of the FCC rules and the
requirements adopted by the ACTA. On the back of the TDM400P 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 the TDM400P 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.
The telephone company may make changes in its facilities, equipment,
operations or procedures that could affect the operation of the equipment.
If this happens, the telephone company will provide advance notice in
order for you to make necessary modifications to maintain uninterrupted
service.
If you experience problems with the TDM400P,contact Digium, Inc.
(877.546.8963) for repair and/or warranty information. If the equipment
is causing harm to the telephone network, the telephone company may
request that you disconnect the equipment until the problem is resolved.
Connection to party line service is subject to state tariffs. Contact the state
public utility commission, public service commission, or corporation
commission for information.

Chapter 1
Overview
The TDM400P card is a device 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 card allows Asterisk PBX software to
connect to your phone network, creating a Small Office Home Office
(SOHO) telephony environment. See Figure 1 for an example of the
card’s primary application.

Chapter 1: Overview
What is Asterisk?
Asterisk is the first Open Source PBX. Since it runs on Linux, it inherits
all of the power and stability of the operating system. The name Asterisk
is derived from the all-inclusive “wildcard” symbol in UNIX, because it
is opening a wide range of opportunities for developers worldwide to
create solutions which would otherwise be cost-prohibitive.
Asterisk allows you to create a PBX solution that rivals the features and
functionality of traditional telephony switches. Current PBX solutions are
expensive and proprietary. International companies are discovering that
Asterisk is cost effective, low maintenance, and flexible enough to handle
all of their voice and data networking. Combined with Digium hardware
and a common PC, anyone can replace an existing switch or complement
a PBX by adding VoIP, voicemail, conferencing, and many other
capabilities. Asterisk will integrate with most standards-based IP
telephone handsets and software. Analog phones and ADSI-screen
phones are also supported.

Shipment Inspection on page 16
Module Identification on page 16
Port Identification on page 16
Hardware Installation on page 20
Software Installation on page 22
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 your reseller where the card was purchased, or Digium
Technical Support (877.546.8963 or 1.877.LINUXME!). 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.

Shipment Inspection
The following items are included in shipment of the TDM400P:
TDM400P card
A combination of FXO and/or FXS modules
Port Identification label
User’s manual
Module Identification
The TDM400P card ships with FXO and/or FXS modules. These are
identified by their color. Take a moment to identify which modules were
shipped with your card.
FXO (Foreign Exchange Office) modules are Red
FXS (Foreign Exchange Station) modules are Green
See Figure 2 on page 18 for an example of the card shown with two of
each module.
Port Identification
Each card consists of four RJ11 ports located on the bracket. Each port
correlates to a module slot (containing the FXO or FXS modules). The
ports are numbered in sequence from one to four. The top port is Port 1
and the bottom port is Port 4. See Figure 2 on page 18 for appropriate
identification of these ports.
Note: It is important to identify the type and location of your
TDM400P modules. You will need this information during the
Asterisk configuration.

Release 1.0 Digium, Inc. Page 17
Chapter 2: Card Installation
There are multiple standard configurations in which the TDM400P card
may be purchased. Each configuration consists of one to four FXS and/or
FXO modules.
It is easiest to identify your card by understanding the naming scheme for
each card. The first digit provides the number of FXS modules present on
the card. The second digit provides the number of FXO modules present
on the card. See Table 1 on page 19 for a complete list of possible
configurations.

Hardware Installation
1. Now that you are acquainted with your card, power down your com-
puter and unplug it from its power source.
2. Attach a static strap to your wrist and open the case.
3. Remove the bracket place holder and insert the card into a 3.3 or 5 volt
PCI slot (PCI 2.2 or greater). See Figure 3.
Caution.
Only qualified service personnel should continue with
hardware installation and configuration of the TDM400P card.
Users should not attempt to perform these functions themselves.
