If you want to take advantage of 128k digital working,

you will need to refer to your Internet Service

Provider or network administrator to check access is

provided at this speed and determine any additional

configuration changes that may be required. You will

be charged for two calls when working at 128k.

When we visit

Simple installation

We can install your ISDN 2e box wherever you want

within your building. It’s simplicity itself to fit and

very easy to service. The actual positioning will be

dictated by how you’re going to be using your new

digital service. For example, if ISDN 2e is running off

a phone system, you would want to locate your box

close to that system. Similarly, if you’re connecting

ISDN 2e to a computer, the box should be positioned

nearby, as this will avoid the need for extension

wiring. And if you’re videoconferencing, consider

if you will need to move the computer or terminal in

the future!

After we visit

Phone numbers

You will have one telephone number with ISDN 2e

for your computer and other digital equipment. If you

want additional numbers, perhaps for other computers,

a Group 4 fax machine or for videoconferencing,

consider Multiple Subscriber Numbering (MSN).

Important supporting information:

• If you want to use analogue phones, faxes, answer

machines and so on, you’ll need a Terminal

Adapter with analogue ports. These are available

from BT and other suppliers (see ‘Communicating

through your computer’ on page 6).

• The number of digital extensions you can have is

largely determined by how far they are located

from your ISDN 2e box, although the maximum

is eight devices, regardless of distance (see page

12 for more information)

• Plan where you may need extension wiring

throughout your premises. We can install digital

extension wiring for a fee. For advice, please call

the ISDN Helpdesk on Freefone 0800 18 15 14.

An alternative is to buy a wiring extension kit

from another supplier and install it yourself. If

you decide to do this, you must check that the

wiring for digital extensions complies with

Category 5 cabling, conforms to ISO/IEC 11801

and is fitted with RJ45 type plugs.

Check with your Internet

Service Provider

If you already have an Internet Service Provider,

check that they support digital access. If they do,

inform them that you require ISDN 2e access. They

may give you an alternative dial up number. You will

then need to re-configure your Internet dialler

software. This also applies to any file transfer or

remote network access connections you may have.
