IBM yesterday also announced a string of Open Systems Interconnection products developed in Europe. The IBM X400 Message Transfer Facility enables applications running under eitherVM/SP or VSE/SP to exchange messages with other entities in an X400 message handling environment. The IBM X400 Profs Connection Program supports interchange of messages between a Profs office system under VM and other X400 systems – over services such as British Telecom’s Message Handling Service. The company also announced release 2.1 of the General Teleprocessing Monitor for Open Systems Interconnection for VM and DOS/VSE users, which now adds facilities for the implementation of X400 applications. It provides an environment for development of Open Systems applications and for connec-tions to SNA and non-SNA programs. The company has also expanded its inter-operation test services that test open systems applications for conformance with the transport layer four and session layer five of the Open Systems model, extending the servives offered by its La Gaude labo-ratory in France. All the services are accessible via the IBM Informat-ion Network Service, and users are charged a one-time payment for the verification process, plus a payment for resources used in the tests. IBM is demonstrating X400 links with about 20 other firms at Telecom 87.
