Introduction 1-1
The H.100 Station Board
1.0Introduction
The Infinity Series H.100 Station Board is designed to provide twenty-four
Station Set interfaces connected to the H.100 bus on a board with the PCI
bus form factor. Each interface or port provides support for basic line
functions such as battery, ringing, and hook-status detection. The board is
equipped with DSP resources to provide tone generation and detection as
well as the generation of Caller ID information. Thirty two channels of voice
record and playback capability are also available. 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 H.100 compatible 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 Station Board.

1-2 Introduction
The H.100 Station Board
1.1.1 The Station Interface
Twenty-four independent ports are provided on the board. Each port on the
board provides a complete interface for a standard telephone device. Talk
battery is supplied along with hook-status detection, and the battery polarity
can be reversed under software control. Ringing can be applied in a number
of different cadences as well as a signal to turn on a message waiting
indicator on appropriately equipped phones. Port timing and characteristics
can be set to adapt to different national standards. Ringing is generated
internally.
1.1.2 Caller Identity
Each port is capable of generating and detecting all the signals necessary for
Calling Number Delivery and Calling Name Delivery. Calling Identity
Delivery on Call Waiting feature is also supported. All timing is done
internally on the board without requiring host intervention.
1.1.3 DSP Functions
The H.100 Station 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
call progress tones are also available. In addition, the DSP has voice record
and playback capabilities which are beyond the scope of this document.
1.1.4 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.
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

Introduction 1-3
The H.100 Station Board
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 Station 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 Station Board. The clock
redundancy and clock fallback functions of the H.100 bus are also supported
so that the H.100 Station Board can be set to provide a clock to the H.100
bus if the master clock on the 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 Station 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.
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 processors and for the DSP’s 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

1-4 Introduction
The H.100 Station Board
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
The board has an EEPROM capable of providing non-volatile storage for
configuration information. This information includes the port type, timing
requirements, and the parameters necessary to conform to various national
standards, supply voltages, etc. 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 Station 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.
3. Read section 5.0 (Communicating with the PC) for an overview of how
to communicate with the H.100 Station Board. Section 5.0 includes a
summary of the commands for constructing your application and details
concerning system interrupts.
Before you develop your application, read sections 6.0 (The H.100 Bus &
Clock Modes) and 7.0 Using the Station Board). These sections explain,
with practical examples, how the H.100 Station Board operates and how to

Quick Start 2-1
The H.100 Station Board
2.0Quick Start
This section describes the first steps you should perform to determine if your
Infinity Series H.100 Station 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 systems, 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 Station 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
