BT Highway

BT Highway was a UK retail ISDN2e service from British Telecom which was announced in November 1997cite web | url=http://www.guardian.co.uk/technology/1997/nov/08/news.internet | title=BT heralds new high-speed Internet surfing at drop in the ocean cost | date=8 November 1997 | publisher=The Guardian] and withdrawn in February 2007cite web | url=http://bt.custhelp.com/cgi-bin/bt.cfg/php/enduser/cci/bt_adp.php?p_sid=&p_faqid=8337&cat_lvl1=346&p_cv=1.346&p_cats=346&s_cid=con_FURL_homehighway | title=When and why did BT withdraw Home Highway? | accessdate=13 June 2008 ] . In the domestic market, it was sold as BT Home Highway and for small businesses, BT Business Highway. These monikers were simply used to differentiate billing schemes; the hardware for both services used the name BT Highway.

Notability the in UK Internet Timeline

Due to ISDN's ability to establish connections in under 3 seconds, BT Highway provided many people'scite web | url=http://www.ciao.co.uk/BT_Highway__87071 | title=Ciao! Reviews of BT Home Highway | accessdate=13 June 2008] first experience of a near always-on Internet connection. The service also provided many people's first experience of an Internet connection that ran faster than a dial-up modem (up to 128kbit/s compared to 56 kbit/s, and with a latency of 75-150ms compared to 150-300ms). BT Highway was available five or more years before the availability of broadband, especially in rural areascite web | url=http://www.sirgeorgeyoung.org.uk/pages/broadband1.htm | title=Sir George Young MP calls for "Broadband Access for All" | date=17 January 2002] where ISDN was available over far longer distances, and far more telephone exchanges, than the initial roll-out of ADSL,

Distinctive Hardware

BT Highway was provided as a wall-mounted panel that supplemented an analogue master socket. A blank faceplate was placed across the analogue master socket so that all connections had to be performed through the panel.

BT Highway was distinctive because, unlike most ISDN services, it was aimed at both home and small business users, and incorporated both analogue sockets (coloured white) and ISDN sockets (coloured blue). It was possible to plug in both Cat5 ISDN equipment and traditional POTS analogue telephones at the same time into the same master panel; normally an ISDN master panel provides only ISDN sockets. As with a standard ISDN2e service, it was possible to mix and match concurrent connections to provide two concurrent analogue phone calls, one analogue phone call and one ISDN 64kbit/s call, two 64 kbit/s ISDN calls or one 128 kbit/s ISDN call. The analogue sockets were standard UK BS6312 sockets and included a ring capacitor.

Unlike an analogue master socket, BT Highway required external power from a mains electric adaptor. However, in the event of a power cut, the system still allowed analogue telephone calls to be made through the first analogue socket.

Connection to the Internet was typically performed either by a dedicated ISDN router or by an ISDN PCI card. As with ISDN2e, most brands of device typically allowed the user to automatically connect and drop the second ISDN channel to switch between 64 kbit/s and 128 kbit/s, depending on whether one channel was already being used (for example, for a simultaneous analogue telephone call).

Introduction and Withdrawal

BT Highway was announced in November 1997 and introduced on an exchange-by-exchange basis starting in September 1998 [cite web | url=http://news.zdnet.co.uk/internet/0,1000000097,2069201,00.htm | title=BT service promises ISDN speed over phone lines | publisher=ZDNet | date=21 August 1998] . BT stopped selling new services on 5 September 2005 and stopped providing BT Highway services altogether in February 2007, encouraging users to migrate to ADSL. Where migration to ADSL was not possible, BT continued to sell their ISDN2e service for business customers only.
