Integrated Digital Services Network (ISDN) is synonymous for those who remember the pre-ADSL days and wanted extra speed, is about to be culled by BT.

BT's consumer ISDN first known as HomeHighway and later MidBand provided 64Kbps or 128Kbps speeds which now seem ludicrously slow compared to today's xDSL technology will be phased out, although there are only belived to be a couple of thousand users in the UK as most have already transferred to quicker xDSL solutions. BT itself stopped taking new HomeHighway orders back in September 2005.

It's not the end of all ISDN connections as BT's ISDN2e services will remain, as this are compatible with BT's 21st Century Network (21CN) and provides an alternative to xDSL services for users where latency and congestion could cause problems, such as outside broadcasting. ISDN delivers what it says on the tin and is not affected, like IP solutions, by how many users are connected or how busy the network is.
