Abstract
After a user device unsuccessfully attempts to establish upstream communication with a central network equipment downstream frequency to which it has tuned, an identifier corresponding to the tuned-to downstream frequency is removed from a cache of the user device. The frequency identifier stored in the cache typically corresponds to a frequency to which the user device has previously successfully tuned. The frequency identifier is removed from the cache after a predetermined attempt period, which may be determined by the number of attempts to establish communication that are made after previous unsuccessful attempts.
