Apple Mac computers will need additional software for

dial-up applications, such as Internet access or remote

access. This is available from most Apple Mac retailers.

If your computer isn’t fitted with an ISDN Card (like a

modem card but digital) or you haven’t got a Terminal

Adapter (like an external modem but digital, which

connects to your computer’s serial port), you will need

to purchase ISDN 2e compatible hardware (meaning it

is compatible with the latest version of ISDN). This

equipment is available from BT and other suppliers.

ISDN Cards cost from around £50 and Terminal

Adapters cost from around £100. Details can be found

on www.bt.com, or call us on Freefone 0800 18 15 14.

Important supporting information:

• While an ISDN Card offers you optimum

performance, fitting one may invalidate your

computer warranty. You should confirm this with

your computer supplier.

• You will need to get in touch with your

equipment supplier for advice on configuration

issues. Their contact details are usually provided

with their documentation.

With MSN (see ‘Digital Select Services’ on page 15),

you can have up to 10 numbers associated with

ISDN 2e. Each number attracts a connection charge

and a quarterly line rental.

We recommend that you note down your numbers in

the Useful Numbers section at the back of this guide

and also on the label on the ISDN 2e box itself.

Phoning and faxing

As soon as your ISDN 2e box has been fitted, tested

by the engineer and correctly configured, you should

be able to plug in ISDN phones and use them straight

away. Check with your supplier on what configuration

is necessary. If you have opted for MSN (see ‘Digital

Select Services’ on page 15) individual phones,

extensions, Terminal Adapters and videoconferencing

terminals may need to be configured so that each

knows when to allow another device to take an

incoming call.

Phone systems may need expert installation and

configuration, so it’s absolutely vital to check with your

supplier on this front.

Communicating through

your computer

ISDN 2e will work with most desktop PCs and Apple

Macintosh computers, as long as they are fitted with a

suitable ISDN Card or connected to a suitable

Terminal Adapter and configured properly. The

recommended minimum PC specification is a 486DX

processor running at 100Mhz, or an Apple Mac with a

68040 processor.
