Note: This manual refers to the revised board using the T8105 switching chip, Blackfin
DSPs, and the HFC8S BRI Interface chip. As these chips are different than those used
on earlier boards, there may be minor differences in the operation of the board. Those
using the earlier revision should use the 258M001A revision of this manual. The revised
board is functionally equivalent to the earlier board with the exception that the voice
record and playback cpabilities have been added. Specifically, this manual refers to
firmware versions 02.0b and later.
Note: The rear board used with this revision of the BRI board has also been revised and
is incompatible with earlier revisions. The front board MUST be used with the revised
rear board and MAY NOT be used with earlier versions of the front board. The revised
rear board MAY NOT be used with earlier versions of the front board. Installing
incompatible front and rear boards WILL result in damage to both boards.

The H.110 Basic Rate ISDN Board
1.0 Introduction
The Infinity Series H.110 Basic Rate Interface ISDN Board is designed to
provide thirty-two Basic Rate ISDN (Integrated Services Digital Network)
interfaces connected to the H.110 bus on a board with the CompactPCI
bus form factor. Each interface or port provides a D channel for call
control signaling and two 64 kbps. B channels for either speech or circuit
switched data. Each port can be independently configured as either a TE
(Terminal Equipment) or NT (Network Termination) interface. The board
provides complete support for the ISDN Layer 1 and Layer 2 protocols, as
well as optional support for the Layer 3 protocols as defined in Q.931. In
addition, the board is equipped with several DSP’s to provide tone
generation and detection.
The H.110 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 CompactPCI form factor. A variety
of boards are available from a number of different vendors. The H.110
specifications also provides for hot swap capabilities for use in high
availability applications.
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.110
boards.
1.1 Features and Capabilities
This section presents an overview of the features and capabilities of the
Infinity Series H.110 Basic Rate Interface ISDN Board.

Introduction• 1-2 •
The H.110 Basic Rate ISDN Board
Figure 1: The H.110 Basic Rate ISDN Board Functional Areas
1.1.1 The Physical Interface
Thirty-two independent ports are provided on the board. Each port on the
board provides a complete S/T Basic Rate ISDN interface. This interface
can be configured under software control as either a piece of terminal
equipment to interface to a central office or PBX, or as a network
termination to interface to terminal equipment such as ISDN phone sets or
ISDN modems. Layer 1 support is provided by the board to handle all the
details of framing and clocking.

Introduction • 1-3 •
The H.110 Basic Rate ISDN Board
Each port provides two independent B1 channels which operate at 64 kbps.
These channels can be switched to the H.110 bus, to each other, or to one
of the DSP resources. In addition, there is a 16 kbps D channel which is
used for signaling.
1.1.2 Signaling Protocols
ISDN uses the LAPD protocol on the D channel for call control. The
Layer 2 protocol defines the mechanism used for the exchange of messages
between terminal equipment and the network termination. The board
manages the details of this protocol while providing commands to control
aspectssuch as TEI (Terminal Endpoint Identifier) address management.
Call control is handled by the exchange of Layer 3 messages as defined by
the Q.931 standard. The H.110 BRI Board allows the application to
directly read and write the raw binary information field of these messages.
Optionally, a higher level interface is provided that masks some of the
details of these messages, making for a simplified applications interface.
This is done through the use of “D” messages.
1.1.3 DSP Functions
The H.110 BRI ISDN Board is equipped with DSP’s that performs a
variety of functions. DTMF and Energy detectors are available for each B
channel. DTMF generators are available for each B channel 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. Additionally, 64 channels of voice record and 64
channels of voice playback are available.
1.1.4 The H.110 Bus
The H.110 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 future development that

Introduction• 1-4 •
The H.110 Basic Rate ISDN Board
would end the “bus wars” between the various legacy busses such as the
SCbus and the MVIP bus.
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.110 bus, each frame
consists of 128 channels or timeslots. The bit rate of the H.110 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.110 bus consists of backplane connections on a 6U CompactPCI
backplanethat is used to interconnect the boards in the system. The CT
Bus connections are made through the J4/P4 connector. The electrical and
mechanical requirements of H.110 boards are tightly specified to insure the
reliability and consistent performance of the CT Bus in any valid
configuration of conforming boards.
1.1.5 Clock Modes
The H.110 BRI Board can operate in a variety of clock modes. Modes are
available so that the master clock can either be derived from the H.110 bus,
one of the Basic Rate Interfaces, or be provided by the H.110 BRI Board.
Theclock redundancy and clock fallback functions of the H.110 bus are
also supported so that the H.110 BRI Board can be set to provide a clock
to the H.110 bus if the master clock on that bus should fail.
1.1.6 Hot Swap Capability
The H.110 Specification includes “hot swap” capability. This capability

Introduction • 1-5 •
The H.110 Basic Rate ISDN Board
allows for the insertion and removal of boards from a live system. Not
only are there provisions for controlling the electrical signals to prevent
disruption when inserting and removing boards, but also for informing
drivers and applications so that the board resources can be managed as they
are added or deleted. Each H.110 board is provided with a blue LED that
is used to inform an operator when it is safe to insert or remove a board.
1.1.7 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 CompactPCI board,
the address and interrupt of the board is assigned at boot time. The
message passing scheme used by the Infinity Series H.110 BRI Board is
identical to that of the other Infinity Series H.110 boards, allowing for the
easy combination of a variety of Infinity Series H.110 boards in a single
system.
The message passing scheme and message syntax of Infinity Series H.110
boards is similar to that of the older Infinity Series H.100 boards and XDS
series of MVIP and SCbus boards. This facilitates the easy migration from
ISA and PCI systems to designs using CompactPCI boards
1.1.8 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
asystem 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.
1.1.9 EEPROM for Configuration Information
ISDN interfaces can require a substantial amount of information to be
programmed into the system. These includes items such as the SPIDs

Introduction• 1-6 •
The H.110 Basic Rate ISDN Board
(Service Profile Identifiers) and DNs (Directory Numbers) associated with
each interface as well as board configuration information such as the type
of port (NT or TE) and the protocol level supported. To reduce the burden
on the application, the board has an EEPROM capable of providing non-
volatile storage for this information. This allows the board to automatically
configure itself upon a restart.
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.110 BRI ISDN Board. We
recommend that you begin with these three steps.
1. Followthe instructions in section 2.0 (Quick Start) and 3.0
