<p>A subscriber line signalling apparatus for use in an asynchronous mode communication system includes a switching circuit (30) having a plurality of input terminals (12-1 to 12-j) and a plurality of output terminals (13-1 to 13-k). The switching circuit (30) selectively communicates fixed length information packets to an adaptation processing unit (100). The adaptation processing unit (100) reassembles the fixed length packets to signalling frames, and transmits them to a frame processor (40).</p> |
