Abstract
A telephone subscriber testing system is disclosed in which all tests may be performed from a central office. A central office test device is connected to the central office by a separate telephone line with a telephone number of its own. Moreover, a dedicated command channel connects the office test device with a remote test device over the carrier lines. This dedicated channel is used to communicate commands and transmit test results back to the central office. By causing the remote device to 'dial up' the office device, the entire trunk loop through the PCM trunk and the central office switching equipment can be tested directly in one measurement at the central office.
