Embodiment Construction

[0045] Detailed description of the preferred embodiment

[0046] FIG. 1 is a schematic diagram of the overall system structure of a communication system 101 according to a preferred embodiment of the present invention. In the system configuration shown in FIG. 1, a plurality of telephone stations 102 are connected to a central telephone exchange 105. As shown in FIG. It should be understood that telephone station 102 includes a telephone, modem, facsimile machine, or other device capable of communicating over a complete call connection. Central telephone exchange 105 will be referred to herein as "Customer Premises Equipment" or "CPE". For example, CPE 105 includes a private branch exchange (PBX) or encryption key system. Various types of PBX and encryption key system designs are known in the art.

[0047] In the preferred embodiment shown in FIG. 1, the CPE 105 is connected to a public switched telephone network (PSTN) 125 and a wireless access communication unit 106 (also...

Abstract

A communication system (101) having a wireless trunk for connecting multiple phone lines (102) over wireless communication links to a cellular network comprises a central telephone switch (105) such as a private branch exchange or key system, connected through one or more trunk lines to a wireless access communication unit (106). The wireless access communication unit preferably comprises a separate subscriber interface (104) for each trunk line from the central telephone switch. The wireless access communication unit (106) collects data from each of the subscriber interfaces, formats the data into a format compatible with an over-the-air protocol, and transmits the information over one or more wireless channels to a cellular base station. The wireless access communication unit thereby provides one or more channels arriving and received from the cellular network to the central telephone switch.

Description

field of invention [0001] The present invention relates to systems and methods for providing communication services. Background of the invention [0002] Localized telephone switching systems such as private branch exchanges (PBX) and encryption key systems have been used in commercial offices and other businesses for many years as an alternative or as a supplement to public telephone service. The PBX system and the encryption key system allow users connected to the system to place internal telephone calls without entering public telephone services. Such a system can provide significant economic benefits, especially if internal system traffic is high. [0003] On the other hand, when a caller using a PBX or encryption key system needs to place a call to a party not connected to the system, such external calls essentially have to be routed through the PBX or encryption key system controller on the landline to public telephone company. To accommodate this dual functionality...
