Introduction 1-1
The H.100 E&M Board
1.0Introduction
The Infinity Series H.100 E&M Board is designed to provide eight E&M
interfaces connected to the H.100 bus. Each interface or port provides both
audio transmission and control support for basic line functions such as hook
status indication and detection for Type I and Type V interfaces. The board
is equipped with DSP resources to provide tone generation. Each port can be
programmed to conform to various national standards and practices.
This board is available in both a PCI and a PCI Express version. This
manual covers both versions. For the purposes of this manual, the PCI and
PCI Express buses will be referred to as the PCI bus except where it is
important to differentiate between them.
The H.100 bus was devised by the Enterprise Computer Telephony Forum
(ECTF) to provide a single telecom bus for the entire industry. It is intended
for add-in boards using the PCI or PCI Express form factor. A wide variety
of boards are available from a number of different vendors.
The board is equipped with a processor that can be used to control the lower
level functions of the board. The host PC controls the board using messages
passed through dual-ported RAM. The board shares a common message
passing and control scheme with other Infinity Series H.100 boards.
1.1 Features and Capabilities
This section presents an overview of the features and capabilities of the
Infinity Series H.100 E&M Board.
1.1.1 The E&M Interface
Eight independent ports are provided on the board. Each port on the board
provides a complete E&M interface, including both the audio and signaling
(E and M leads) connections. Type I and Type V E&M interfaces are
supported for either the trunk or the signaling side of the connection. The

1-2 Introduction
The H.100 E&M Board
audio may be transmitted using either a 2-wire or a 4-wire interface. The 4-
wire interface separates the transmit and receive pairs. The signaling and
audio interface type are software selectable on a port by port basis without
using jumpers.
The on board firmware provides support for the common address signaling
protocols such as immediate start, wink start, and delay-dial for both
incoming and outgoing calls. Incoming calls can use either DTMF or pulse
signaling of the address digits. Outgoing calls are limited to DTMF address
digits. All timing is handled by the on board processor. For special
applications such as interfacing to two-way radio transceivers, the M-lead
can be controlled directly by the application.
1.1.2 DSP Functions
The H.100 E&M Board is equipped with a DSP that performs a variety of
functions. DTMF and Energy detectors are available for each port. DTMF
generators are available for each port for signaling purposes. Call Progress
tones are also available, with dial-tone, busy, reorder, and audible ringback
being provided as well as silence and a 1004 Hz calibration tone. European
ETSI call progress tones are also available. In addition, the DSP has voice
record and playback capabilities which are beyond the scope of this
document.
1.1.3 Transceiver Support
The H.100 E&M Board has a number of features that have been added to
facilitate interfacing with transceivers used in two-way communications
systems. These added features include, programmable echo suppression, a
push to talk feature that uses the M-lead to key the transmitter when voice
energy is detected, and 2100 Hz tone detection to disable echo suppression
when connected to a modem. These features may be enabled on a per port
basis.
1.1.4 The H.100 Bus
The H.100 bus is a digital bus for transporting PCM (Pulse Code
Modulation) signals between telephony boards. It was created by the ECTF
to provide a common bus structure for computer telephony.

Introduction 1-3
The H.100 E&M Board
PCM is a standard method of digitizing phone signals. It involves encoding
each channel at an 8 kHz rate using eight bits. The signals from multiple
channels are then combined into a frame. On the H.100 bus, each frame
consists of 128 channels or timeslots. The bit rate of the H.100 bus is 8.192
MHz. Thirty-two wires, also called streams, each carrying 128 timeslots, are
combined to form the bus, and provide a total of 4096 timeslots. Two
timeslots are required for a full conversation, one for each talker.
In addition to the streams, a number of other signals necessary to maintain
synchronization between all the boards in the system are carried on the bus.
These signals provide the clocking and framing information. Redundant
clocks are provided to aid in recovery if the primary clock should fail.
The H.100 bus consists of a 68 conductor ribbon cable that is used to
interconnect the boards in the system. This cable connects to a header at the
upper right hand edge on each board.
1.1.5 Clock Modes
The H.100 E&M Board can operate in a variety of clock modes. Modes are
available so that the master clock can either be derived from the H.100 bus
or be provided by an internal source on the H.100 E&M Board. The clock
redundancy and clock fallback functions of the H.100 bus are also supported
so that the H.100 E&M Board can be set to provide a clock to the H.100 if
the master clock on that bus should fail.
1.1.6 Message Passing
The board occupies 8K of memory space on the host PC. This 8K may
reside anywhere within the PC’s address space. As a PCI or PCI Express
board, the address and interrupt of the board is assigned at boot time. The
message passing scheme used by the Infinity Series H.100 E&M Board is
identical to that of the other Infinity Series H.100 boards, allowing for the
easy combination of a variety of Infinity Series H.100 boards in a single
system.

1-4 Introduction
The H.100 E&M Board
The message passing scheme and message syntax of Infinity Series H.100
boards is similar to that of the older XDS series of MVIP and SCbus boards.
1.1.7 Flash EAROM for Firmware
The firmware for both the main processor and the DSP is contained in Flash
EAROM. This allows for easy upgrades of the firmware on the board in the
field without requiring time consuming downloads every time a system
boots. Once reprogrammed, the new firmware is retained even when the
power is removed. The original, factory programmed firmware is also
retained on board and can be accessed by installing a jumper.
1.1.8 EEPROM for Configuration Information
To reduce the burden on the application, the board has an EEPROM capable
of providing non-volatile storage for configuration information. This
information includes the port types, timing requirements, and address
signaling protocols. This configuration information, when saved, is
automatically restored on a restart, allowing the board to automatically
configure itself without host intervention.
1.2 How to Use This Manual
The first five sections in this manual are organized in the order you should
read and use them to get started with your H.100 E&M Board. We
recommend that you begin with these three steps.
1. Follow the instructions in section 2.0 (Quick Start) and 3.0 (Installation).
These sections will tell you if your board is operating correctly within
your system. You don’t need to be familiar with the board’s command set
to complete this step.
2. Read section 4.0 (Initialization) to initialize the board within your
system. Your application must perform these initialization procedures
whenever you power-up your PC in order for the board to communicate
with the PC.

Introduction 1-5
The H.100 E&M Board
3. Read section 5.0 (Communicating with the PC) for an overview of how
to communicate with the H.100 E&M Board. Section 5.0 includes a
summary of the commands for constructing your application and details
concerning system interrupts.
Before you can actually build your application, read sections 6.0 (The H.100
Bus & Clock Modes) and 7.0 (Using the E&M Board). These sections
explain, with practical examples, how the H.100 E&M Board operates and
how to use the command set to achieve the desired results. Section 8.0
(Diagnostics & Error Messages) explains diagnostic and error messages that
may occur.
The Appendices contain information on power requirements and interfacing
that will be helpful when installing your H.100 E&M Board.

Quick Start 2-1
The H.100 E&M Board
2.0Quick Start
This section describes the first steps you should perform to determine if your
Infinity Series H.100 E&M Board is communicating correctly with your PC
system. You can perform this quick check without securing the board to the
PC chassis or connecting any cables.
The exact procedure will vary depending on which operating system you are
running. For each operating system, drivers are required to interface to the
boards. The drivers supplied by Amtelco have tests built into them to verify
communications with the boards. These drivers also come supplied with
utility programs that allow the developer to test communications with the
board. Please consult the appropriate documentation for the driver and
operating system you are using.
Quick Start Procedure
1. Make sure the PC power is off, then insert the board into a PCI or PCI
Express slot as appropriate.
2. Turn on your PC.
3. If the Amtelco driver is not already installed, install it now, following the
instructions supplied with the driver.
4. Most Amtelco drivers will display a list of boards that are installed (see
the documentation for the particular driver that you are using). If the
H.100 E&M Board is listed, skip to step 6.
5. If the board is not listed, there may be a problem with the board not being
seated correctly in the motherboard. There may also be a problem with a
memory or interrupt conflict. Power down the PC and check that the
board is properly seated in the connector and repeat steps 1-4. If this does
not remedy the problem, try removing any other computer telephony
boards in the system. If your PC is unable to find the board, contact
Amtelco for technical assistance.

2-2 Quick Start
The H.100 E&M Board
6. Run the program “xdsutil” supplied with the driver. Send the message IN
to the H.100 E&M Board. The board should respond with the message
IA.
7. Send the message VC to the board. Verify that the Receive Message
reads: VCxxxxvvvvPEC(where xxxxvvvv is a variable indicating the
firmware version).
8. If the Communications screen shows the correct command responses,
your H.100 E&M Board is communicating with the PC. You may now
power down the computer and attach the necessary cables (see section
3.4).
