The Plessey strategy for its US Stromberg-Carlson unit of targeting the big market for smaller rural digital telephone exchanges is paying off with a second order from one of the Bells: this time, it is the Pacific Telecom arm of Pacific Telesis, which wants two DCO host exchanges, three Remote Network Switches, a Remote Line Switch and an RLS-4000, totalling about 31,000 lines, for Northern California; no value was given; last year the company, now part of the new GEC Plessey Telecommunications Holdings Ltd, won orders for DCOs from South Central Bell covering five states.
