摘要 PCT No. PCT/FI92/00292 Sec. 371 Date Jun. 22, 1993 Sec. 102(e) Date Jun. 22, 1993 PCT Filed Oct. 29, 1992 PCT Pub. No. WO93/09623 PCT Pub. Date May 13, 1993.A method for handling data transmission frames of variable length in the interface between two networks, and for writing them into a cyclic buffer memory (3) wherein the data transmission frames are made of a header field (H) containing at least control data, a data field (D) and an end field of variable length. To obtain flexible buffering, the buffer memory (3) is divided into more than one logical section, each having a header field and a data field. The indicated real length of an incoming frame is taken into account: in the buffer memory operations in such a manner that the channel decoder (4) is interrupted for each frame section which have come from the channel to the area of the buffer, whereby the channel decoder reads the frame sections to its own memory, whereby the last interrupt related to the frame is made on the basis of the indicated real length of the frame when the last section of said frame is in the buffer.
