ETSI - ETS 300 116

Attachments to the Public Switched Telephone Network (PSTN) Category II Attachment Requirements for 1200 Bits per Second Duplex Modems Standardized for Use on the PSTN (the Text of This ETS May Be Utilized, Wholly or in Part, for the Establishment of NET 22)

inactive
Organization: ETSI
Publication Date: 1 January 1991
Status: inactive
Page Count: 32
scope:

This ETS specifies the technical characteristics to be met by modems seeking Category II approval for duplex operation over the PSTN at 1200 bits per second. The modulation scheme specified is that described in CCITT Recommendation V.22 [1].

NOTE: CCITT Recommendation V.22 [1] also describes a method of transmitting data at 600 bits per second. This ETS specifies the characteristics to be met by such modems and, if requested by the applicant, this feature can also be approved as Category II.

The term "modem" in the context of this ETS includes all physical implementation practices for voice band modems which are galvanically connected to the PSTN.

This ETS specifies four modes of operation each with five modes of use (see subclause 5.2).

This ETS also contains descriptions of the tests to be performed in order to confirm compliance with the functional requirements contained herein. A general description of the test conditions and test requirements is given in Annex A (Normative).
