European Digital Cellular Telecommunications System (Phase 2); Use of the V Series Data Terminal Equipment - Data Circuit Terminating Equipment (DTE - DCE) Interface at the Mobile Station (MS) for Mobile Termination (MT) Configuration (GSM 07.06 Version 4
This technical specification describes an optional protocol for use at the `R' reference point (the DTE/DCE interface) allowing a terminal equipment (TE2) to configure the mobile terminal (MT) using the 'V' series interface only. The protocol across the `DTE/DCE interface may use character mode or block mode commands (sent from the TE) and responses/indications (sent from the MT). If this technical specification is implemented then the character mode protocol must be implemented whereas the block mode protocol is optional within this specification.
