Classification: CPC H | IPC H

Claim 9:
10. A timing synchronization method comprising:
with a slave line card, generating a plurality of slave line card time stamps for a respective plurality of slave line card frame sync signals generated on the slave line card;
with a master line card, generating a plurality of master line card time stamps for a respective plurality of master line card frame sync signals generated on a master line card;
comparing at least some of the plurality of slave line card time stamps to at least some of the plurality of master line card time stamps;
adjusting at least one timing aspect of the master line card based on the comparing;
determining a temperature coefficient for the master line card; and
compensating for temperature change based on the temperature coefficient and a current temperature reading.
