A New International Exchange<br />
in Kuwait<br />
Abdullah Al-Sabej<br />
On August 75,7977, the subscribers in Kuwait were given the possibility of dialling<br />
automatic international calls. On this date, a new international SPC exchange was<br />
put into operation. This exchange was the first of the LM Ericsson system ARE 13<br />
with the processor system ANA 30.<br />
The ARE 13 system has previously been described in a serie of articles in Ericsson<br />
Review^3.<br />
This article will therefore only briefly describe the functions that are<br />
characteristic of the exchange in Kuwait as well as the experiences gained from the<br />
installation and putting into service of the exchange.<br />

A smaller international exchange of<br />
non-LM Ericsson design for operator<br />
assisted traffic was already in operation<br />
in Kuwait, but due to the demand for a<br />
larger system to handle international<br />
subscriber dialled traffic, the Ministry of<br />
Communications announced a public<br />
tender in 1975. After studies of various<br />
bids, the Ministry selected the ARE 13<br />
system from LM Ericsson. Among the<br />
features of the ARE 13 system that received<br />
most consideration, were:<br />
— The large line capacity and traffic<br />
handling capability of the system, up<br />
to 24 000 multiple positions (triple<br />
exchange) and 300 000 calls per hour.<br />
The modularity of the system makes it<br />
possible to extend it economically in<br />
order to meet the dramatically increasing<br />
international traffic demand<br />
in Kuwait.<br />
— The advanced operator and charging<br />
facilities with toll-ticketing, TT.<br />
— The modular and standardized design<br />
of both software and hardware,<br />
which provides high reliability and<br />
easy handling.<br />
Installation in two phases<br />
In accordance with the contract the first<br />
phase of the ARE 13 exchange with about<br />
650 international circuits should be<br />
taken into service on 30.11.1977. However,<br />
through the <strong>com</strong>bined efforts of all<br />
parties concerned, it was possible to<br />
take the ARE 13 into service on
