CAUTION

Since IA12 ISDN Adaptor is an electronic-based product, the requirements below should

be fulfilled, in order to utilize it with desired performance:

The adaptor must not be disassembled by unauthorized
persons in any way.

The cover of the adaptor cabinet should always be kept
closed.

Prior to hanging the adaptor on the wall, one should make
sure screws are not defective.

Precautions must be taken in order to prevent any harmful
substances from leaking or spilling into the adaptor in any way.

Failure in fulfilling these requirements may result in vital hazards!

PREFACE

Chapters in this guide have been prepared in order to present detailed technical
information to people who need hardware-based information about the IA12 ISDN
adaptor and instructing them for installation of the adaptor. By this way, one could
understand abilities of the IA12 ISDN adaptor, how it will be operated in accordance
with customer demands and things that should be done in order to operate it with full
performance.

First chapter - “Technical Introduction” - It contains technical information about
hardware and software structures of the adaptor. Information in this chapter, for
which knowledge in mechanics, electricity and electronics may be prerequisite, aims
to introduce structure of the adaptor. Presentation of the information in this chapter
follows a path from the whole of the adaptor down to the details of parts.

Second chapter - “Installation” - This chapter tells about the installation methods
according to the capacity of the adaptor. This chapter definitely must be read before the
installation by the personnel who will perform the installation of the adaptor.

Third chapter - “Programming” - This chapter gives short information about the software
characteristics, which would enrich functions of the adaptor and which could be applied
to meet daily communication needs of customers more comprehensively.

Last chapter-”Usage” - This chapter explains the things to be done in order to put the
device in use.

Best regards,

Karel

IA12 ISDN ADAPTOR

TECHNICAL INTRODUCTION

IA12 ISDN is a EURO-ISDN BRI compatible adaptor that serves as a converter between
analog lines of the MS-series exchanges (MS48S, MS128, MS224) and ISDN BRI lines
coming from local CO (NT1).

TECHNICAL SPECIFICATIONS

An IA12 ISDN Adaptor with basic capacity can serve an ISDN BRI line. That capacity could
be increased by addition of the EXP-IA12 expansion card, which supports one ISDN BRI
line, to IA12.

Since each ISDN BRI presents two speech channels, IA12 with EXP-IA12 can convert 4
analog lines of the MS systems to 2 ISDN BRI lines, whereas IA12 without EXP-IA12 can
convert only 2 analog lines to 1 ISDN BRI line.

The IA12 ISDN Adaptor communicates with the MS systems over the serial data line (KTS
line). At most 3 IA12’s can be connected to an MS system. However, in that case it is
possible to install an EXP-IA12 in the third adaptor.

Current ISDN line capacities of the MS systems have been explained in the example
below:

The IA12 motherboard is connected by an 8-pin, RJ45 socket to the S0 that comes
from the NT1, to the A/B terminals of analog lines of the MS systems by two clip-type
connectors and to the serial data line by a 6-pin, RJ-type jack. At one end of the data
cable, which comes with the IA12, there is the connection box and at the other end there
is an RJ jack.

The EXP-IA12 expansion card is connected by an 8-pin, RJ45 socket to the S0 that
comes from the NT1, to the A/B terminals of analog lines of the system by two clip-type
connectors. The EXP-IA12 expansion card comes with a flat cable for connection to IA12,
which fits the 20-pin connectors of the IA12 motherboard and the EXP-IA12 card.

Moreover, there are three LEDs on the IA12 motherboard in order to monitor status of
the S0 line, as well as the data line. The LED at the right is turned on while the adaptor
and the ISDN line that is connected to the IA12 motherboard is operating simultaneously,
the LED in the middle is turned on while the adaptor and the ISDN line that is connected
to the EXP-IA12 card is operating simultaneously and the LED at the left is turned on
while the adaptor and the data line is operating simultaneously.

Appearances of theIA12 Motherboard and the EXP-IA12 card have been illustrated below;
