Mondial DISC (1988)

"Thorn Ericsson Telecommunications and AT & T and Philips Telecommunications have been awarded orders worth more than £30 million by British Telecom for two new large international telephone exchanges of advanced digital design."

"The two exchanges-an AXE10 design from Thorn Ericsson and a 5ESS PRX from AT & T Philips-are being bought for British Telecom International (BTI) and both will come into service in 1988 at London's Kelvin House and Mondial House respectively. By 1990, they will provide an extra 80,000 lines to help meet continuing high growth."

In order to close the Mondial TXK2, an AT&T 5ESS DISC was installed to carry all the minor routes that Mondial specialised in. The 5ESS was itself withdrawn in the 1990s, so it had a short life.
