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. 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 the computer is powered up in order for the
board to communicate with application.
3. Read section 5.0 (Communications with the Computer) for an
overview of how to communicate with the H.110 BRI ISDN 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 section 6.0 (The H.110
Bus and Clock Modes), 7.0 (Layer 1 and Layer 2 Protocols), 8.0 (Using
“D” Messages for Layer 3) and 9.0 (Controlling the B-Channels). These
sections explain, with practical examples, how the H.110 BRI ISDN Board
operates and how to use the command set to achieve the desired results.
Section 10.0 explains diagnostic and error messages that may occur.
