With a normal analogue modem connection, your data needs to be translated, sent over the phone line, and translated again. Any errors cause a slow response. Since ISDN is a digital connection to the Internet, you can achieve much faster and more stable connections. Each ISDN channel is like a separate phone line, so you can use one ISDN line to connect two computers to the Internet at the same time. Alternatively you could ‘Multilink’ both channels to dial up together – providing for 128 Kbps of bandwidth. You will then pay for 2 phone calls instead of one at a time.

You need a computer plus the following to access the internet:

1. A Telkom ISDN Line, and
2. An ISDN modem (also known as a terminal adaptor), and
3. An Eject dial-up account with the relevant ISDN option (64 or 128 Kbps)

There are two types of ISDN lines available from Telkom: ISDN 2 and ISDN 2a.

With ISDN 2a you can also plug your standard telephone, a fax machine and your computer directly into the ISDN line. Note that you can only use two of them at a time. We do recommend that you install ISDN 2a, given the slight difference in price.
