Claim 0:
1. A network communications system comprising:
a master line card including a master line card counter and a master line card time stamp circuit, the master line card time stamp circuit configured to provide a plurality of master line card time stamps corresponding to a plurality of master line card frame sync signals generated on the master line card, the plurality of master line card frame sync signals each indicating a roll over event for the master line card counter;
a slave line card including a slave line card counter and a slave line card time stamp circuit, the slave line card time stamp circuit configured to generate a plurality of slave line card time stamps corresponding to a plurality of slave line card frame sync signals generated on the slave line card, each of the plurality of slave line card frame sync signals indicating a roll over event for the slave line card counter;
a processor configured to compare one of the plurality of slave line card time stamps and one of the plurality of master line card time stamps and generate a baseline difference, to generate a second difference according to a comparison between a second one of the plurality of slave line card time stamps and a second one of the plurality of master line card time stamps, and the processor responsive to a mismatch between the baseline difference and the second difference to adjust a timing aspect of the master line card to compensate for the mismatch.
