A point-of-sale computer has an I/O port generating command and data information corresponding to the specific set of command signals and data signals required for the selected telephone to be programmed and for reading the preassigned serial number of the telephone. An interface converts the information into the specific set of command and data signals required for the selected telephone to be programmed. The interface has a telephone interface port through which the specific set of command signals and data signals are provided. The interface reads the preassigned serial number via the telephone interface port. An RS232 cable connects the I/O port of the computer and the interface. A passive cable with an RJ45 connector connects the telephone interface port of the interface and the programming port of the selected cellular telephone. The point-of-sale computer provides the system computer via modem with the preassigned serial number of the selected cellular telephone being programmed thereby permitting the system computer to verify that the selected telephone can access the CT system.
