ABSTRACT:
A wireless interoffice facility (IOF) is provided by a microwave network that overlays a public switched telephone network. The wireless IOF may be used by a carrier or other service provider to obtain needed bandwidth where the PSTN does not have sufficient capacity, the available capacity is too expensive, redundancy is needed or it is desirable to provide services that are alternative to or complementary with those provided by other common carriers. The wireless IOF may also be used to provide inter-LATA or interstate service without the need for an inter-exchange carrier.
