Going back to its roots, Computer Consoles Inc, Waltham, Massachusetts, whose telephone products are marketed in the UK by STC Plc, has unveiled an Automated Listing Services system for telephone companies that are expanding on-line non-classified telephone directory services. The new system is based on a fault-tolerant configuration of Computer Consoles’ hardware and software, and is designed to expand telephone company directory services into new revenue-generating products such as Customer Name and Address and address retrieval services for operators. The system also supports direct customer access via public packet networks to these databases for business and industry, and viewdata access for residential users. The company sees the system as applicable to direct marketing, listing content verification, demographic studies, and mailing list maintenance. The Automated Listing Services system is based on Computer Consoles’ Power6/32 FT fault-tolerant minicomputer system runn ing the company’s Perpetual Processing Operating System implementation of Unix System V, and proprietary CCI database management software. Terminals supported include VT100 compatible asynchronous terminals and specialised viewdata terminals and it also supports the Northern Telecom TOPS/MP and the Rockwell CallPro operator positions. British Telecom’s directory enquiry computer systems come via STC from Computer Consoles, but are based on the previous generation DEC PDP-11 based product line.
