ISDN Basic Rate Interface (BRI)
ISDN BRI offers either 64Kbps or 128Kbps data transfer rates. Calling Line Identification Presentation (CLIP) is offered as standard.
Basic Rate Interface (BRI) can support two dial-up services at the same time. One line could be used for data access and the other for voice calls, for example. A maximum of 8 multi-subscriber numbers can be associated with a Basic Rate ISDN line.
A 2Mbps pipe from the exchange to your business provides thirty channels, each at speeds of 64Kbps. They can be used for voice and data dial-up services.
With ISDN PRI, almost all modern voice and data communication systems from PBXs, mainframe and distributed systems through to your company LAN/WAN can be connected to your ISDN service.
The use of routers, multiplexers, ISDN controllers and video/audio conferencing units is also supported.
Additionally, Digital Telephone Switches can use our Direct Inward Dialling (DID) facility over PRI. DID offers a single interface for up to 30 concurrent calls, as well as for up to two hundred free DID extensions.
