A 32 bit digital "amended electronic serial number" (AESN) is generated from a 56 bit "extended electronic serial number" (EESN). The AESN distinguishes each subscriber unit within a wireless system from each other subscriber unit. Two distinct methods are disclosed. In the first method, a manufacturers code field ("MFR") is tested to determine whether the subscriber unit has been assigned an EESN. If so, then the least significant 8 bits of the manufacturer's code field ("EMFR") are appended to the "serial number" field ("SN"). In the second method, each manufacturer generates serial numbers by applying a pseudo-random sequence. The "seed" for the pseudo-random sequence is based on the manufacturer's EMFR. This serial number is then combined with the 8 bit MFR. |
