Abstract

PURPOSE:To reduce the number of lines to connect exchanges in case of using two exchanges by connecting, etc., by allocating plural specific dial numbers on one line wire. CONSTITUTION:By dialing in a specific number to capture a central office 3 or a dedicated line 4 by either extension telephone sets 2a-2m, the specific number is inputted to a control part 14 via a dial handset 15. The control part 14 retrieves a line wire number corresponding to the specific number from a table TB2 when it is the specific number, and detects the vacant line wire in a priority order or an even order, and when no vacant line wire exists, detects a vacant line in another specific number group, and captures the line. Therefore, by connecting a first exchange to a second exchange by one dedicated line, and allocating '2'-'4' as the specific dial numbers to capture the dedicated line at the second exchange when the first exchange is provided with the extension number of four digits starting from 2-4, it is possible to call the extension telephone set in the first exchange by performing the dial operation such as '2XXX'-'4XXX'.
