Abstract: PURPOSE: A method for inactivating BTS channel elements using a CSM(Cell Site Modem)2000 ASIC is provided to achieve the inactivation of a channel element without having an effect on the other channel elements in an identical chip. CONSTITUTION: If inactivation for an arbitrary channel element in a BTS is determined(S101), a mobile system judges whether an inactivation command is transferred from a BCP(BTS Control Processor)(S103). If the inactivation command is transferred, the system judges whether the kind of a channel defined to the channel element is an overhead channel or a traffic channel(S105). In case that the defined channel is the traffic channel, the system judges whether the state of the present channel is busy(S107). If the state of the present channel is busy, the system releases the ongoing traffic call(S109). Then the system disables all possible interrupts which can be generated and stops the operation of a CSM completely(S111). The system initializes the database used in the channel element(S113) and turns off the LED of the channel element(S115). Then the system transfers a transmit summer to a bypass mode to prevent forward link output(S117). The system initializes the CSM2000 ASIC variables of the channel element only(S119) and reports an inactivation result for the channel element to the BCP(S121).
