Abstract

PURPOSE:To prevent an outgoing register from being used exclusively for a long time in a specific extension, by providing two signal paths for an outgoing sender trunk and monitoring the abondonment on the way with one signal path. CONSTITUTION:When an extension A makes a call, it is connected to an outgoing register OR via a channel 1. If, the A makes an abbreviated dialing, for example, then this signal is received at the OR, and the central controller CC reads in said information from the OR and stores it. When the transmission of a dial signal is completed, the CC opens the channel 1, closes channels 2, 3 and connects the extension A to a signal line S2 of an outgoing sender trunk OST and a central office trunk to a signal line S1 respectively. While a dial signal is transmitted from the OST to the main trunk, the extension loop of the extension A is monitored from the signal line S2, and if the abondonment on the way of outgoing of the extension A is detected, the operation of an exchanger to the extension A can all be restored with the control of the CC.
