Abstract

PURPOSE:To reduce the burden of an operator by connecting the first extension subscriber and simultaneously dialing the second subscriber, when an operator of the B board sets a series call. CONSTITUTION:An operator of the B board ATT answers a main wire incoming call, and connects the main wire with the first extension subscriber EXT1. After that, when the operator dials the second extension subscriber EXT2, this dial information is stored in the series call register SCR. When the subscriber EXT1 is released, the clearing information is sent out to the register SCR from the central office line trunk COT. The register SCR sends out the dial information for the subscriber EXT2, to the marker M by said information. By this information, the marker M designates a channel (2) in the switch frame F, and calls the subscriber EXT2.
