Abstract:
1. Telecommunication equipment, comprising: a TDM interface operable to receive STS-n data, where n is equal to a number of STS-1 time slots in the STS-n data; a packet interface operable to receive packet/cell data and fill a STS-MC payload with the packet/cell data, wherein M is a number of time slots in the STS-MC payload; an STS-1 switch comprising an n×n cross-connect coupled to the TDM interface and operable to switch and assign each of the n STS-1 time slots of the STS-n data received at the TDM interface to any one of n STS-1 time slots; a multiplexer coupled to the cross-connect and the packet interface and operable to combine the switched STS-n data and the STS-MC packet/cell data into an STS-N payload for transport, where N is a number of time slots in the STS-N payload and is equal to the sum of n and M; and a framer for framing the STS-n signal for transport on an optical carrier; wherein the STS-N payload includes the STS-MC at the beginning of the payload and the STS-n at the end of the payload; and wherein n and M are greater than zero.
