Abstract:
A method for communicating data between first and second transceiver facilities over a serial link, comprising, at said first transceiver facility;receiving, from said second transceiver facility, a first superframe comprising a serial series of data frames, each data frame having a serial plurality of words comprising a plurality of payload data words and a non-payload word;a non-payload word for two of said frames of said first superframe comprising a facility data word, a first one of said facility data words providing a facility alarm and status data and a second one of said facility data words providing facility data unrelated to the communication of payload data;at least where said second facility data word is not a word indicating an idle condition, queuing said second facility data word on a FIFO buffer;where said FIFO buffer is within a pre-set number of words of being full, constructing an alarm and status facility data word with an indicator indicating said FIFO buffer is full;constructing another facility data word having facility data unrelated to the communication of payload data;constructing, at said first transceiver facility, a second superframe comprising a serial series of data frames, each data frame having a serial plurality of words comprising a plurality of payload data words and a non-payload word;one non-payload word comprising said alarm and facility data word with said full indicator and another non-payload word comprising a facility data word having facility data unrelated to the communication of payload data; andsending said second superframe to said second transceiver.
