Abstract
A system and method are provided for communicating TDM communications through a packet switch fabric. The method comprises: accepting native TDM frames; converting the native TDM frames to fabric-cellified TDM frames; differentiating the cells of each frame into time slots; interleaving the frame time slots; TDM scheduling the interleaved frame time slots; and, routing the interleaved frame time slots between input port cards and output port cards on backplane data links through an intervening crossbar. TDM scheduling the interleaved frame time slots includes: an input port card ingress memory subsystem (iMS) receiving a first TDM configuration schedule including interleaved frame time slots cross-referenced to backplane transmission times; and, an output port card egress MS (eMS) receiving a second TDM configuration schedule including interleaved frame time slots cross-referenced to egress channel transmission times. Then, the routing is performed in response to the TDM schedules.
