SSH ETS 300 492:1996 ed.1

Public Switched Telephone Network (PSTN); Category II specification for 14 400, 12 000, 9 600, 7 200 and 4 800 bits per second duplex modems standardized for use on the PSTN

Scope

This European Telecommunication Standard (ETS) specifies the technical characteristics required for end-to-end interworking over the Public Switched Telephone Network (PSTN) of 14 400 bit/s, 12 000 bit/s, 9 600 bit/s, 7 200 bit/s and 4 800 bit/s duplex modems standardized for use over the PSTN, in accordance with CCITT Recommendation V.32 bis [1]. The objective of this specification, the application of which is entirely voluntary, is to provide the users with an added degree of assurance that modems in compliance with this specification, can interwork, with each other under most network conditions.
