Overview of the ACB ISDN Service

An initial ACB (Automatic Call Back) ISDN service, based on a small ISDN router connected to a home computer (PC, Mac or Linux) via an Ethernet card is available. It currently offers only Internet access (direct access to NICE and Appletalk files is under investigation). To use ISDN your home must be cabled for digital access to your local Telecom supplier.

The ACB ISDN service is offered in addition to the existing ACB modem service.  The ACB modem service will continue to be operated and improved (56kbps modem access is planned for later this year).

Choosing between the ISDN and Modem ACB services

• guaranteed throughput at 64 or 128 kbps (see Note 1 below)
• low latency - giving good interactive response time
• fast connection time
• can make phone calls while using the network

• no extra monthly rental or installation costs (see Note 2 below)

Note 2: Installing ISDN in your home costs significantly more than an analogue telephone line. ISDN monthly charges are roughly equivalent to the rental of 2 analogue lines.
