1. In a digital cellular system (DCS) with the capability to detect a faulty cellular communications device (CCD) in use in the system, said DCS comprising:
- at least one CCD;
a base station subsystem (BSS);
a base station management unit (BSMU) for managing operations of the BSS, said BSMU comprising;
a memory storing information concerning predetermined faults; and
a base station controller (BSC) for controlling multiple devices in a hierarchical fashion; and
a base station transceiver system (BSTS) for communicating information regarding a faulty CCD to the BSMU;
the improvement comprising;
a portion of said memory storing said information concerning predetermined faults, said information concerning predetermined faults constituting data concerning selected ones of said predetermined faults, stored at distinct addresses corresponding to respective ones of said predetermined faults, said information concerning predetermined faults not containing measurements of parameters of signals transmitted by the base station and CCDs; and
a means for detecting faults of said BSC and devices of said BSC and for reporting corresponding ones of said distinct addresses to enable said BSMU to access fault messages corresponding to said addresses from said information concerning said predetermined faults.
