Abstract:
1. A channel allocation apparatus of an OSU in a WDM system comprising: an optical signal converter for performing a conversion operation between an E1 data frame and an optical signal; a channel allocating unit for performing a counting operation by a certain unit on E1 data and detecting an channel allocated to the E1 data, the channel allocating unit including a demultiplexing unit to detect data assigned to each channel, the demultiplexing unit including: an E1 framer for refraining the E1 data frame outputted from the optical signal converter to output it to the channel allocating unit, and framing the E1 data outputted from the channel allocating unit to output it to the optical signal converter; and a microprocessor for controlling an operation of the E1 framer.
