Testing a subscriber terminal of a wireless telecommunications system
First Claim
1. A subscriber station for the wireless connection of user telephone set to a remote central station of a wireless telecommunications system, said subscriber station comprising:
- a transmitter/receiver for wireless communication with the remote central station;
a communications controller coupled to the transmitted receiver for processing signals for transmission and/or received signals;
subscriber telephone set coupled to the communications controller by at least one telephone line; and
a high impedance test circuit connected across said telephone line, said high impedance test circuit operable to provide testing of said subscriber telephone set and said telephone line.

Abstract
A subscriber station provides the wireless connection of user telecommunications equipment to a remote central station of a wireless telecommunications system. The subscriber station includes a transmitter/receiver for wireless communication with a central station and for processing signals for transmission and/or received signals, at least one telephone line for connection to subscriber telecommunications equipment, and a high impedance test circuit connected across a telephone line under test. The use of a high impedance test circuit means that the test circuit can effectively be connected permanently across a telephone line under test. By effectively connecting the high impedance test circuit permanently across the telephone line under test, that is connecting the test circuit across the telephone line during all operational conditions of the telephone line, the test circuit is able to provide a range of test functions, including self-test functions in a cost effective manner, which would not be possible with the conventional test circuits which are only switched in during line testing.
