Adventures in Broadband: ISDN

by Jeffrey Race

What is ISDN

For communications-intensive individuals or businesses, TOT and TelecomAsia are

now promoting an old but highly cost-effective system, the Integrated Services Digital

Network.

It sounds daunting, but a bit of self-education can bring you greatly enhanced commu-

nications at nominal cost. The hurdle is getting an overview of a technically complicat-

ed service, understanding how to make it work for you, how to install the hardware,

and how to set it up.

This article aims to tell the reader how he can benefit from ISDN and what time and

financial budgets he needs to accomplish his aims.

Who doesn’t need ISDN? Anyone who needs only a single phone line, who doesn’t go

on the internet, or who uses the internet but values his time at less 15 baht per hour (the

difference between analogue and ISDN internet access rates) and doesn’t care if his

callers get a busy signal.

Who needs ISDN? Anyone who needs a phone line and would like to be able to use a

another phone, or fax, or the internet simultaneously. Or anyone who goes on the Net

and values his time over 15 baht per hour.

It is also an excellent alternative to leased lines for businesses with a branch network

and/or which use the internet extensively, or which wish to support telecommuting.

(Numerous commercial packages exist to allow full office computer network and tele-

phone system functionality to appear at a remote location via ISDN.)

What does a successful ISDN installation require? After reading this article, you may

need an hour to arrange installation of the phone line (the service providers will fax you

the form), and perhaps a day to contact equipment vendors to get competitive quotes

for the best hardware for your installation.

The hardware can cost from 2,000 baht to 15,000 baht depending on your needs, but

some ISPs offer it at reduced price with an ISDN-enabled subscription and throw in

installation as well.

Then you will have to wait several weeks for the line, which costs the same as a regular

phone line. (Some optional ISDN features cost extra.) Setup of your hardware and

configuration of your computer may take half an hour. That’s it!

What does an individual user get? With Basic Rate Interface (BRI, also called Basic

Access Interface, abbreviated BAI) silent Internet logon in four seconds (instead of 30-45

seconds of modem screeching), and web downloads at two to four times the maximum

speed one can expect from an analogue dialup line.

When TOT resolves an internal dispute, one will also be able obtain multiple phone

numbers for a reduced price. Companies can choose the more expensive Primary Rate

Interface (PRI) and achieve 30 times this for their branch networks or telecommuters.
