ISDN Lines

It's not just big companies that need high-quality telephone lines.

More and more people are working in small offices or at home. With a choice of ISDN2e or ISDN30/30e you can enjoy exceptional line quality and fast and error free data transfer.

ISDN 2

The decision between using the Analogue Lines and ISDN2 does not just come down to cost. By using ISDN2, new features can be introduced into your company's telephone system and enabling use of additional applications, which will empower your business to grow and take up any innovative opportunities offered by your customers and suppliers. Your company will take a further step from the analogue to the digital age.

An Analogue line can be converted to a Basic Rate ISDN2 (BRI) line with two channels, or a new line can be installed. To use a stand-alone computer for ISDN2 you need an internal or external "Terminal Adapter" which is similar to a computer modem. For a local area network (LAN), you need a router and/or an ISDN PBX or similar device. For computer telephony applications, an ISDN PBX with a computer interface is essential.

If you wish, you can have separate phone numbers for telephones or other devices connected to your circuit. If you use a switch/PBX, you can have a number of Direct Dial-In (DDI) numbers.

ISDN 30

If your business employs over 100 people or typically spends over £20,000 a year on calls, then ISDN 30 solution is ideal for your needs.
