PCT No. PCT/AU87/00305 Sec. 371 Date Mar. 8, 1989 Sec. 102(e) Date Mar. 8, 1989 PCT Filed Sep. 8, 1987 PCT Pub. No. WO88/02206 PCT Pub. Date Mar. 24, 1988.An interface arrangement (2) comprising interface circuits (5,7) and processor (14) allows a personal computer (10) to operate in conjunction with a telephone subset (1) associated with a main switch system (9) in which the signalling systems used by the telephone subset and the computer differ. The interface arrangement allows the subset and the computer to be connected to the subsets switching system to permit at least some of the subsets signalling functions to be performed by the computer.
