Abstract (en)

[origin: WO8911768A1] A class marking apparatus for use in telephone exchanges of the kind having means in use generating a call signal indicating that a telephone call is being made on a telephone line with which the exchange is associated, and means providing a line identification signal identifying the telephone line, the apparatus including a first interface (18), a microprocessor (12), memory (26, 28) and a second interface (30). The first interface (18) is effective, in use, to receive the common line identification signals and to interface the line identification signal to the microprocessor (12). The memory (26, 28) is adapted to store class marking data for subscriber telephone lines and the microprocessor (12), on receipt of the called signal, is effective to address the memory (26, 28) so as to access class marking data relating to the telephone line identified by the identification signals. The second interface (30) is effective to receive the accessed class marking data from the microprocessor (12) and interface the access data to the output of the apparatus.
