Abstract

PURPOSE:To prevent a representative group from occupying a call of a specific device, by providing a means for limiting the number of calls, which is set simultaneously between a device which is capable of communicating with plural terminals simultaneously, and a representative group constituted of plural terminals, to a prescribed number or less, on a switching network. CONSTITUTION:Terminals T1-T5 constituting a representative group PG, other terminal T6 and T7, subscriber terminals d1d6 of a device D which is capable of communicating with 6 terminals simultaneously are stored in a network NW of an electronic switchboard, and are connected to each other under the control of a central processor CC using a main storage device MM. When a call is set through paths 1-3 in the NW, between the subscriber terminals d1-d3 of the device D and terminals T1-T3 belonging to the PG, discriminating information of the d1-d3 is stored in the MM. Subsequently, when the D originates a call addressed to the PG by use of the d4, the CC refers to the discriminating information in the MM, and counts the discriminating information of the d1-d6. When the result of counting is equal to the number limit 3, it is inhibited to set a call addressed to the PG from the d4. In this way, the call occupancy of the specific device is prevented against the representative group, and at least 2 terminals of the T1-T5 can be used for a call to the T6 and T7.
