The OSI/Network Management Forum international organisation formed by British Telecommunications Plc, AT&T Co and like-minded companies as a body devoted to speeding the implementation of Open Systems Interconnection standards, has announced the addition of four new Associate members, bringing total membership to 63 telecommunications and computer companies. Joining the Forum are McDonnell-Douglas Network Systems Co, Stratus Computer Inc, Teknekron Communications Systems Inc, and the Ungermann-Bass Inc subsidiary of Tandem Computers Inc. The Forum’s second document, which defines an inital set of application messages, is now under review by the membership. The work of the Forum is being handicapped by the insistence of IBM and DEC to pursue proprietary systems for network management, but the Corporation for Open Systems and the Standards Promotion & Application Group have teamed up to create a united front on the issue (CI No 1,181).
