Abstract
An apparatus and method for a synchronous optical network (SONET) includes ordering a plurality of signals of a first type in one or more line cards for transmit to one or more types of line cards, wherein the ordering of the first type of signals creates a plurality of independent signals of a second type, and transmitting the plurality of the first type of signals to the one or more types of line cards, wherein the independence of the signals of the second type permits the one or more types of signals of the second type to be in an arbitrary order. The method and apparatus includes ordering in a plurality of modules to assign to a variable A a number of basic modules on the one or more line cards, assign to a variable B a number of processors adapted for STS-N signals on the one or more line cards, calculate a variable C by dividing A by B, C being the number of basic module channels common to each of the processors, calculate a variable D by dividing C by three, D being a number of contiguous channels, divide each STS-N signal into N/D portions, each portion including up to D bytes, and for each portion of the STS-N signal, select one of the number of processors adapted for STS-N signals, and transmit the portion of the STS-N signal to the one of the number of processors.
