This TS specifies the Radio Link Protocol (RLP) for circuit switched data transmission within a PLMN.
RLP provides to its users the OSI Data Link Service.
RLP is intended for use with non-transparent data-transfer. Protocol conversion may be provided for a variety of
protocol configurations. Those foreseen immediately are:
character-mode protocols using start-stop transmission (IA5);
For reasons of better presentation, material about protocol conversion has been placed within those specifications
concerned with the relevant Terminal Adapters, i.e. TS 27.002
for the asynchronous case and
for the synchronous case. Care must be taken that that material also applies to Interworking
Functions; see TS 29.007
This TS is valid for a PLMN in A/Gb mode as well as in Iu mode. If text applies only for one of these
systems it is explicitly mentioned by using the terms "A/Gb mode" and "Iu mode". Please note, that the Gb interface does not play any role in the scope of the present document although the term "A/Gb mode" is used.
