ABSTRACT:
A programmable signal generating apparatus and method are provided such as for creating a continuous SONET signal. The apparatus preferably comprises a DRAM, a memory address register, a loop counter, an address stack, an instruction decoder, and a SONET data output interface. The DRAM stores a plurality of words at a respective plurality of memory locations. Each word is preferably comprised of three bytes of SONET data and a command byte. One or more command bytes specify a command, and a plurality of commands are decoded by the decoder to generate a plurality of program sequences. The program sequences cause the SONET data bytes which are part of the data words to be generated into continuous SONET frames. The SONET data bytes do not act as typical data operands in that they have no effect upon program operation, but are simply used to generate a SONET data stream.
