    Coral66 was a compiled structured programming language, of the Algol family, used for real-time system development. A popular Switch in the UK during the 1980s/1990s was System-X (GPT – GEC Plessey Telecommunications).

    System X was based on Post-Office Coral 66, hence POCoral66. At the time the General Post Office was the main Telecommunication Provider. After the GPO was privatised this became BTCoral66.

    PO/BT Coral 66 is a Real Time Language that was used by System X. During the 1980s CPU, Storage and Memory were expensive and this meant that you needed compact code to work with the Hardware limitations.

    Look forward to your System-X questions.

    GPT’s System X.

    Telent dot com still supports and enhances the former System-X Digital Switch from GPT.

    The System X product comprises of a range of digital telephone exchanges and concentrators that were the centre of the digitisation of public telecommunications networks in the UK throughout the 1980’s, 1990’s and early 2000’s. These national networks were built to last delivering 99.999% availability and even today the majority of fixed network voice and data calls will at some stage be processed by a System X exchange.

    Telent have developed an innovative life extension programme capable of sustaining System X till 2025.

    System X History.

    System X was a leading edge UK digital narrow band Switch (Telephone Exchange) that was incepted and developed during the 1980s.

    System X was designed by a consortium of companies that included: General Post Office (Now British Telecommunications, or BT), Plessey, GEC and STC. It was a joint engineering collaboration with the main telecommunication incumbent (GPO/BT) and leading engineering companies that had specialised competence with Digital Switching. Around 1984, BT was privatised.

    The Switching Fabric was designed by Plessey, GEC designed the Processor, STC designed the Concentrator, the GPO (now BT) took control of the overall Management System. Overall, the whole System-X development Project was backed by the GPO/BT. Soon the consortium merged and one company was formed – GPT – GEC Plessey Telecommunication. STC soon dropped their involvement with System X.
