A private wireless communication system (56) is interconnected with a public switched telecommunications network (PSTN). The wireless system (56) includes a mobile telephone switching office (MTSO) (58). A first cell site (60) interconnects with the MTSO (58) through a first PSTN-provided T-1 transmission link 64. A second cell site (62) interconnects with the MTSO (58) through a second PSTN-provided T-1 transmission link (66), and with the first cell site (60) through a third PSTN-provided T-1 transmission link (68). Additionally, the first cell site (60) interconnects with a local exchange carrier (LEC) end office (72) of the PSTN through a fourth PSTN-provided T-1 transmission link (70). The first and second cell sites (60, 62) are located in a local service area (80) of the LEC end office (72), and the MTSO (58) is configured to selectively route communication signals over first, second, third, and fourth PSTN-provided T-1 links (64, 66, 68, 70).
