Dialogic ® SPCI2S and SPCI4 Boards User Manual Issue 7

2 Introduction
2.1 Purpose
This document is a User Manual that addresses the Hardware aspects of the
Dialogic
® SPCI2S and Dialogic ® SPCI4 products. These products are SS7
Signaling Boards in PCI form factor.
Collectively, the two board variants may be referred to as Equipment Type
SPCI. The full Product IDs (ordering codes) for the two variants are
SS7SPCI2SQ and SS7SPCI4Q, although in this User Manual, and many other
documents, they are commonly known as SPCI2S and SPCI4.
This User Manual includes the specification of the products and a functional
description. It details all the interface connections, including pin-out, and
provides installation instructions.
It should be read in conjunction with the Dialogic ® SS7 Boards Programmer’s
Manual for SPCI2S and SPCI4 ∗ which gives further information on the use of
the boards, including a description of configuration parameters and
commands.
2.2 Overview
The SPCI2S and SPCI4 boards are intelligent multi-port SS7 signaling
interface boards capable of use in a telecommunications environment.
Embedded software support for many signaling systems is available including
the entire Signaling System Number 7 (SS7) protocol stack.
The SPCI4 board supports up to four primary rate telecommunications
interfaces; each can individually be configured at run-time under software
control to operate as an E1, T1 or J1 interface. The SPCI2S board supports up
to two primary rate telecommunications interfaces, but also supports up to
two synchronous V.11 (V.35 compatible) serial interfaces.
The on-board H.100 Computer Telephony (CT) Bus interface and digital
switch allows timeslots to be routed between the E1/T1/J1 interfaces, the
H.100 CT Bus and the on-board signaling processors. This enables bearer
(voice) circuits to be routed to other resource boards and permits flexible
routing of signaling timeslots through the system.
A signaling processor provides support for multiple HDLC-based signaling
channels including up to 4 SS7 signaling links. The signaling links may be
presented either as a timeslot on an external PCM interface, as a timeslot on
the CT Bus, or as a synchronous V.11 (V.35 compatible) serial interface.
Signaling links can all operate at 64kbit/s, 56kbit/s or 48kbit/s.
Software downloaded to the board at run-time implements the signaling
protocol and provides a message-based interface to the user's application
software running on the host computer. Software for several signaling
systems is available, including the following SS7 protocols: MTP, ISUP, TUP,
SCCP, TCAP, MAP, IS41 and INAP.
Software drivers for the board are available for many host operating systems,
including: Microsoft Windows
® 2000, Windows ® XP, Linux and Solaris.
