Abstract
An improved fixed wired system and method of originating a call in a fixed wired system in which a remote station (10), which is wired to a communication terminal (15), such as a standard telephone, detects an off-hook state of the communication terminal (15), transmits a call origination request signal to a base station (20,25) via a radio link in response to the off-hook state detection, and delivers a dial tone to the communication terminal (15) upon receiving an acknowledgment from the base station (20,25). After a dial tone is delivered to the communication terminal (15) and the user begins dialing a directory number, the remote station (10) collects the dialed digits and forwards the dialed digits separately or in groups, to the base station (20,25) where the digits are analyzed to determine whether a complete directory number has been dialed. When the base station (20,25) detects that a complete directory number has been dialed, it forwards the dialed digits to a communication network (40), such as a public switched telephone network or an integrated services digital network for further processing.
