Faster connections and more digital services

ISDN30 gives you crystal clear call quality for up to 30 phone lines. They’re ideal for businesses with more than eight phone lines and you can use them for connecting people in small offices or at home.

  • Get call quality
    ISDN30 is a high-performance voice and data service. Digital technology gives you great line quality, almost instant connections and crystal clear calls with other ISDN users. Of course, you can make and take calls to and from analogue systems.
  • Data gets through fast
    You can depend on fast and error-free data transfer every time. Each ISDN30 connection gives you between eight and 30 independent 64k channels. You can combine them for bandwidth-hungry applications like high-quality video conferencing or transferring big data files. ISDN is also great for wide-area networks linking different offices.

ISDN30 allows you to connect between eight and thirty 64k channels (lines),so, these can all either be used separately, allowing multiple calls to be made and taken or combined to increase bandwidth.

ISDN30 connections can also be used with a digital switch or phone systems to manage your calls more effectively.

But it's not just about using the lines separately. Your lines can be combined to cater for high bandwidth needs such as video conferencing (both parties in a video-conferencing session need ISDN access and compatible equipment) or transferring large files.

Another benefit is that an ISDN30 connection gives you the choice of an unlimited number of DDI (Direct Dial In) numbers - this means anyone dialling in get directly through to the right department or person without having to go through a switchboard.

ISDN30/30e can be used for creating a Wide Area Network (WAN) by linking 2 or more Local Area Networks (LAN) this allows you to link multiple offices together. The link requires a router at each end, to connect the LAN hubs to the ISDN line.

ISDN30 is also supported by most exchanges so it is available in most areas.
