An initiative started in 1989, under the Computer Board, with the aim of developing of a national
broadband network to support UK higher education and research. The preparatory work culminated in 1992 with the award of a contract worth 18M pounds to British Telecom to provide
networking services over a four year period that extends to March 1997. The BT contract will provide a national
network with two components: a high speed, configurable bandwidth
network serving up to 16 sites, initially using
PDH to be replaced with
SDH, and a high speed switched data service (
SMDS) serving 50 or more sites. The primary role of the PDH/SDH component will be to support the development and deployment of an
ATM network. These components will be complemented by several high performance
Metropolitan Area networks each serving several closely located sites. The aim is to provide, within the first year of the project, a pervasive
network capable of supporting a large and diverse user community. The
network has two parts, an
IP data
network and an ATM
network, both operating at 34Mbit/s. Early in August 1993 the pilot IP
network was transferred to full service and was configured to provide a trunk
network for JIPS, the {JANET IP Service}. In November 1993 work was well advanced on the next phase which aims to extend SuperJANET to a large number of sites. The pilot four site ATM
network will be extended to serve twelve sites and will expand the scope of the video
network. The principal vehicle used for the expansion of the data
network will be the
SMDS service provided by
BT. Most of the work associated with the development of this phase is expected to be completed by the end of March 1994. [Joint
