CHARACTERISTICS AND PROTOCOLS FOR TERMINALS FOR TELEMATIC SERVICES IN ISDN


ITU-T T.90 SPANISH-1992 发布历史

This Recommendation defines the functional profile for base standards ISO/IEC 7776, 8208 and 8885 to provide the lower layers of the telematic services protocol stack when operating on the ISDN. Parameter values are recommended to ensure good throughput when operating via long delay connections such as satellite routes. Backward compatibility with the Blue Book version has been maintained. Three methods of negotiating the lower layer parameter values have been included to satisfy various connection scenarios, e.g. completely within the ISDN or between the ISDN and other digital networks. This Recommendation supplies the network layer definition in Recommendation T.70 for telematic terminals but not the transport layer definition which is still retained as the telematic transport layer definition.
