Nortel IVR 2.5/S Aculab-Based E1 CAS/ISDN PRI Signaling Guide
Chapter 1: Introduction
Overview
This manual provides information on the Aculab E1 CAS/ISDN PRI
signaling option update for MRS 3.02.02, including
• system hardware and software requirements
• a brief description of the new E1 CAS/ISDN PRI signaling features
• hardware and software installation procedures
Also
• Appendix A shows how to connect to the MRS system and log in to the
SCI.
• Appendix B shows the configurations of the Aculab ACL-30 and
ACL-60 E1 cards.
CINFO cell limitation over DPNSS
The CINFO cell is used to pass information from the switch up to the
application to allow the application to route calls appropriately. However,
when the call is coming in over DPNSS, the CINFO cell can only process
three types of information: the DNIS, ANI, and CLC. This is indicated by 0,
1, and 3 respectively in the CINFO cell. Attempting to retrieve other
information forces the application to take the NO_DATA branch from the
cell.

Chapter 2: System requirements
The base Nortel IVR 2.5/S system already includes the system requirements
listed here for installing and using the Aculab-based E1 CAS/ISDN PRI
Signaling option update for MRS 3.02.02. Specifically, these requirements
are
• MRS 3.02.02 software running on the MRS
• SCO UNIX Release 3.2 (Version 4.2) operating system
• MRS/AP , MRS/Tower , and MRS/Rack with at least 32 Mbytes of
memory and 128 kbytes of cache memory

Chapter 3: E1 CAS/ISDN PRI
enhancements
Integrating the Aculab E1 CAS/ISDN PRI card into the MRS enables an
attachment to a 2.048 Mbps telephone digital connection, which supports
several signaling systems.
The MRS 3.02.01 E1 CAS/ISDN PRI option update provides the following
enhancements:
• Using the /sci/maint menu, MRS 3.02.02 base package provides the
ability to initialize channels for all Aculab hardware-based options.
• MRS 3.02.02 also provides new E1 CAS signaling firmware.
MRS currently supports one Aculab E1/ISDN card per system. Both 30-port
and 60-port Aculab cards are supported.

3-2 E1 CAS/ISDN PRI enhancements

• China #1
• Mexico
• Malaysia (Singapore)
• Ericsson E&M (EEMA)
ISDN PRI
MRS 3.02.02 supports the following E1 ISDN PRI network protocol:

• BOUT or CONP cell call conferencing (through Aculab’s on-board
switching matrix)
In addition to the basic functionality listed above, Enhanced DPNSS protocol
implementation also supports the following functionality:
• Call diversion information transfer to an application
• Called line ID transfer to an application
• Route Optimization (when supported by your PBX or switch)

Chapter 4: Installing the Aculab E1/PRI
signaling option
Before installing this option, your MRS system must have MRS version
3.02.02 installed. The base Nortel IVR 2.5/S system includes MRS 3.02.02
software, so it should already be installed on your MRS.
This chapter describes how to install the Aculab-based E1/PRI Signaling
option hardware and software onto your MRS system. It also shows you how
to configure the SCI country parameters for your desired signaling option.
The installation is divided into three main steps:
1 installing the signaling option hardware
2 installing the signaling option software (for CAS or ISDN)
3 configuring the country parameters (for CAS or ISDN)

4-2 Installing the Aculab E1/PRI signaling option
Standard 1.0 July 1997
Installing the Aculab E1/PRI signaling option hardware
Procedure 4-1: Installing the Aculab E1/PRI signaling option hardware
1 Wear an antistatic wrist band when handling the option cards. Unpack
the Aculab E1/PRI Signaling option card(s) and remove them from the
antistatic bag.
2 Shut down the MRS system as described in the appropriate MRS
system product manual.
3 Once the shutdown process is complete, turn off the power to the
system.
4 Configure the Aculab E1 interface card(s) as shown on the
configuration drawings in Appendix B. The Aculab E1 interface card(s)
must be installed at the end of the PEB or PEBs. The illustrations and
tablesinAppendixBillustrateproperI/OAddressing,BoardOperation,
and Hardware Interrupt settings. Please read the notes that follow the
tables.
5 Open the system and find an open slot where you can install the
Aculab E1 interface option card(s). Follow the recommendations in
Step 4.
6 Remove the PEB cable from the cards that will be connected to the
Aculab E1 Interface card.
7 Slide the Aculab E1 Interface card into the system. Do not tighten the
retaining screws yet.
8 Reconnect all the cards together with the PEB cable. You may need to
lift some cards from their slots to attach the PEB cable.

CAUTION
Risk of equipment damage
Always observe proper precautions when working with
the system. Be sure to follow all applicable Electrostatic
Discharge (ESD) guidelines during configuration and
installation of the option cards.

software
Note: New systems are pre-loaded at the factory with both CAS and
Enhanced DPNSS protocols. The software installation procedures
discussed in this section are required only for restoring the software or if
the signaling option is purchased separately after the initial purchase of
the base system.
There are two types of signaling option packages you can install:
• CAS signaling option (see Procedure 4-2 on page 4-4)
• Enhanced DPNSS ISDN PRI signaling option (see Procedure 4-3 on
page 4-7)
Procedure 4-2: Installing the CAS signaling option

Do you wish to continue the installation [y/n]:
ATTENTION
If you installed the CAS signaling option for Belgium, Brazil, China,
Mexico or Malaysia, the system prompts you to enter the number of
Direct Dialed Inward (DDI) and Calling Line Identity (CLI) digits to be
used. (DDI and CLI are equivalent to DNIS and ANI, respectively.)
Consequently, it is suggested that you know the number you will need
before installing the country parameters. (If you do not know the
appropriate number, specify a sufficiently high number of digits.)
