1, at first, pent encoder n, framer n and transmitter n are opened in the administration of energy conservation unit of chip A.At this moment, distributor still distributes free word at the encoder n that is sendaisle n.
2, the administration of energy conservation unit sends the message of " corresponding receive path is opened in request " to distributor, by distributor, this information is inserted the burst control word.This burst control word is fed to chip B by one of them of sendaisle 1-n.
3, after this, multiplexer continues to monitor the data that take in, and, when the burst control word of finding to carry " corresponding receive path is opened in agreement " message, informs the administration of energy conservation unit.
4, the administration of energy conservation unit is after the announcement that receives multiplexer, and toll offering distributor can be to encoder n allocative efficiency data.
Accordingly, to reopen the workflow of pent n paths (withdrawing from power save mode) as follows for chip B:
1, the multiplexer of chip B continues to monitor the data that take in, when finding to carry the burst control word of " corresponding receive path is opened in request " message, according to the channel number n in " corresponding receive path is opened in request " message, remove to open receive path n(and comprise receiver n, deframer n, decoder n).
2, as the deframer n of receive path n by the free word that receiving chip A sends, complete the word boundary locking, and after completing the passage alignment, notify energy-conservation administrative unit.
3, the administration of energy conservation unit after the announcement that receives deframer n, sends " corresponding receive path is opened in agreement " message to distributor, by distributor, this message is inserted the burst control word.This burst control word is fed to chip A by certain sendaisle of chip B.
