ABSTRACT:
An arrangement and method for providing a dial pulse muting function to prevent the sender outpulsing from being heard is to disable the sampling of the transmit to the network side of the trunk circuit which is connected through the time switch and to the receiver from the network side of the line circuit. This function takes place in the trunk circuit, rather than the line circuit, so that less equipment is required. The function, furthermore, is provided through the use of integrated circuit chips as opposed to relays so that less space is required and the arrangement is far more reliable.
