ABSTRACT:
An apparatus and method reduce jitter in SPE data transmitted to a switch fabric. A processor receives STS channel requests from the switch fabric, and retrieves SPE data in buffers assigned to the requested STS channels. The processor loads the SPE data in the PDU of a TDM cell, the TDM cell in the PDU of a PIC, and a length of the SPE data in the header of the PIC. The PIC is then embedded in a CSIX frame that is transmitted to the switch fabric through a CSIX interface. The length of the SPE data in the PIC PDU is variable since the processor retrieves SPE data upon demand from the switch fabric. Thus, even if enough data to fill an entire PDU is not in a channel buffer at the time of a channel request, the available data is transmitted so that the opportunity to transmit available SPE data is not lost.
