ISDN2 - ISDN30

ISDN2

ISDN2e is a high-performance voice and data service for small offices. With a basic installation you can connect up to 8 digital devices and make 2 calls at once.

ISDN also offers 64/128k Internet access - useful if Broadband hasn't yet reached your exchange.

A 2-channel ISDN2e circuit costs about the same as 2 conventional phone lines.

ISDN30

An ISDN 30 provides the capacity for between 8 and 30 continuous voice calls. These calls can be both from people calling into your office, or the calls you make from your office to other people. For each call you will require 1 channel. If you require less than 8 continuous voice calls then you will need ISDN2. If you need more than 30 channels, you can just order additional ISDN 30.
