Patent ID: 7369569

Claim:
A small-sized base station controller providing a flexible board design, including: a first shelf comprising: a Network Synchronization clock distribution Block (NSB block) for generating a plurality of system synchronization clocks and network synchronization clocks using a synchronization clock received from a Global Positioning System (GPS) satellite and distributing the clocks to each shelf in a base station; and an Air Termination Processor block (ATP block) to be used to match with a mobile terminal in a wireless environment; and a second shelf comprising: a TransCoder & ATM (asynchronous transfer mode) E1/T1 Link Block (TAB block) having an ATM E1/T1 Link interface Block (ALB block) for providing an interface between networks and a TransCoder Bank (TCB block) for processing voice compression signal transmitted through the base station from the mobile terminal and PCM (pulse code modulation) data transmitted to an exchange; and a Main Control Block (MCB block) for loading corresponding Operating Systems (OSs) with respect to the NSB block, ATP block and TAB block using backboard identifiers, controlling switching of signals and collecting all generated alarm signals.
