Abstract
A signalling pre-processor for receiving signalling from a line card of a telephone line. The pre-processor converting analog signalling into digital form and integrating the digital signal to remove noise spikes which would otherwise appear as false traffic. The system further includes bit packing for receiving digital signalling in the form of 8-bit bytes and forming 32 bit words, each 32 bit word containing the data from a single bit address of 32 of the 8-bit bytes. These 32-bit words are packed into a memory array until all bits of a given order for a time sample have been gathered. Signal processing is then performed on the 32 bit word to update a state machine for determining the signalling state of each telephone line.
