Apparatus and method for mapping high density E1 signals into a digital cross-connect matrix space

摘要

Apparatus and method are provided which map E1 signals into a logical space of a predetermined number of DS1 signals. 24 selected DS0 signals that are part of each E1 signal are mapped into the space of one DS1 signal in the logical space. The remaining eight DS0 signals of every three E1 signal are then interleavingly mapped into the space of one DS1 signal in the logical space. Depending on the defined logical space, additional E1 signals are mapped into the logical space in the same manner until the predetermined number of DS1 signal spaces in the defined logical space are filled.
