Abstract

Abstract PCT No. PCT/FI95/00674 Sec. 371 Date Aug. 6, 1997 Sec. 102(e) Date Aug. 6, 1997 PCT Filed Dec. 11, 1995 PCT Pub. No. WO96/19065 PCT Pub. Date Jun. 20, 1996The invention relates to a method for cordlessly connecting a data terminal to a data transmission network using the DECT telecommunications system. In the method of the invention, the portable radio part (PP) and fixed radio part (FP) insert signalling information according to the V.24, for example, in frames complying with the DECT protocol to be radio transmitted via the air interface. When using signalling internal to the data channel it is advantageous to use an auxiliary protocol complying e.g. with the V.110 standard. Local signalling can also be used, in which case the data channel need not be used for signalling during data transmission. The method can also be used to transfer the automatic call setup commands according to the V.25bis standard. The method of the invention facilitates a short-range cordless data connection which is compatible with other DECT applications and which can use advantageous DECT system components.
