摘要 |
An improved dialling code processor (12) that is adapted to connect to a telephone line (11) in parallel with other devices (13) that use the same telephone line (11). The processor (12) may operate by: (a) detecting at least one dialling signal placed on a telephone line (11), and (b) inverting the detector signal to form a modified signal, and (c) placing the modified signal on the telephone line (11), wherein the modified signal is adapted to substantially cancel out the original detected dialling signal on the telephone line (11).
