A system for providing a wireless connection from a cell site to its own operations and maintenance panel (OMP). A new unit is built into a cell site on the radio shelf that includes features of a cellular telephone. Such unit includes a modem so that a laptop or other type of computer may be plugged in. This system operates in a plurality of modes, so that it can communicate with any or all of the wireless telecommunication system types (such as AMPS, TDMA, CDMA), and frequency ranges (i.e, 850 MHz and microwave). While the system is installation, the wireless telephone unit can communicate with another type of wireless system. However, once the system comes on line, the unit can communicate with other cell sites in the area from its own system, thus reducing the cost of maintenance. Furthermore, such a system can be used for informing the OMP of alarms such as an intruder alarm, etc. Advantageously, after installation, emergency telephone service or other directly connected telephone service, may be provided by this system.
