Lynn-Arthur Associates, Inc. (LAA) announces its Operator Reference Data
Base (ORDB) for the A.T.& T. 5ESS(R) telephone switch. The ORDB provides
on-line access to a suite of databases used by telephone operators to
answer caller questions and to handle emergency situations. The ORDB
connects to the specialized telephone operator workstations through the
A.T.& T. 5ESS(R).

The ORDB will be delivered by year end to three telephone companies,
Minnesota Equal Access Network Services (Plymouth, MN), Compania
Dominicana de Telefonos (Santo Domingo, Dominican Republic), and
Brazoria Telephone Company (Brazoria, TX). Minnesota Equal Access is a
network services company owned by more than sixty small telephone
companies in Minnesota. Compania Dominicana de Telefonos is a GTE owned
wireline telephone company which serves the entire Dominican Republic.
Brazoria Telephone Company is a small family-run company located an
hour's drive from Houston, TX.

The ORDB is implemented in Objective-C in the NextStep operating system
using distributed objects. It is available to run on Intel and Hewlett-
Packard computers. The ORDB is a high-demand mission-critical applic-
ation delivered on two redundant computer systems. The A.T.& T. 5ESS(R)
switch is connected to the ORDB over a number of X.25 digital links. The
number of links is dependent on the number of operators and expected
transaction loads.

LAA delivers the ORDB as a turn-key solution of hardware, software,
tariff database, training, and installation support. Delivery takes
approximately six weeks from contract signing.

ORDB consists of five major software components. Three of these
components run on NextStep and the fourth and fifth run in the
DOS/Windows environment.

1. The "Operator Service" component receives all the queries from the
operators connected to the 5ESS switch, processes them, and answers the
transactions. All knowledge of the 5ESS switch is within.

2. The "TeleRate(tm) Rating" component performs all pricing of telephone
services. All knowledge of telephone services, their costs, and the
database of tariffs is within. This service provides rate information
for customer queries.

3. The "ORDB Control" component is an application which communicates
with the real-time process to stop, start, monitor, and modify the
mission-critical ORDB application.

4. The "ORDB Data Control" is a Windows application for the operator
service data clerks who control the data on which operator services are
based.

5. The "RTRS Data Control" is a DOS/Windows suite of applications for
the tariff analysts who control the data on which pricing is based.

"TeleRate(tm) Rating" and "RTRS Data Control" components are used in our
real-time rating product and act as servers when more than one applica-
tion which use them is running.
