Patent ID: 7856029

Claim:
A radio base station comprising: a radio equipment controller (REC) portion; a radio equipment (RE) portion; an internal interface which connects the radio equipment controller (REC) portion and the radio equipment (RE) portion; at least one of the portions comprising: a memory for storing one or more previously proven combinations of line bit rate and protocol as stored combination(s) for use on the internal interface; a controller which, prior to synchronization of the internal interface: (1) retrieves the stored combination(s) and includes at least one of the stored combination(s) in a temporary available set of combinations of line bit rate and protocol; (2) initiates a start-up procedure for the internal interface to determine efficacy of the temporary available set for synchronization of a physical layer and alignment of line bit rate and protocol over the internal interface; (3) should synchronization of a physical layer by the start-up procedure succeed, stores a resulting valid combination from the start-up procedure and uses the resulting valid combination for negotiating a best combination; and (4) sets the temporary active set to be the valid combination of line bit rate and protocol should the best combination fail in the start-up procedure.
