Abstract
A time slot interchanger ( ) includes a D-channel processing device ( ). The D-channel processing device ( ) includes a main memory ( ), a D-channel memory ( ), and a D-channel assembler ( ). The main memory ( ) receives telephony data and signaling traffic from a subscriber in the form of integrated services digital network signals. Two-bit D-channel signaling portions of each integrated services digital network signals are extracted and placed into the D-channel memory ( ). The D-channel assembler ( ) assembles the two-bit D-channel signaling portions into eight-bit digital signal level zero (DS0) signals. The eight-bit DS0 signals are stored in the D-channel memory ( ) for subsequent transfer with selected telephony data traffic from the main memory ( ) over a synchronous optical network link.
