scope:
For connection of terminals with SMS functions to the MT, the use of the R or S interface reference points is specified in TS GSM 03.40.
This Technical Specification defines a protocol for use of the V
series DTE/DCE interface over the R reference point for SMS and CBS
procedures. It covers the commands which may be issued from the
terminal (DTE) to the mobile termination (DCE), and
responses/indication
Within this specification, all references to "V.25bis" refer to the CCITT blue book version, unless explicitly stated otherwise.
The SMS/CBS protocol across the DTE/DCE interface uses
asynchronous mode commands (issued by the terminal) and
responses/indication
This specification considers the mobile termination to be a single entity. Other GSM Technical Specifications describe the split of functionality between the mobile equipment and SIM.
The protocol described here is not mandatory, and it is therefore permitted for a manufacturer to implement proprietary protocols. However, these protocols must follow the procedures described in section 2 below, except for the 'END SMS MODE' command described in section 2.2. This command may have a different syntax in proprietary protocols, although its function (ie. the return of the MT and TE into the default mode) must remain unchanged.
