Abstract

PURPOSE:To attain the effective use of an exchange network by avoiding the use of the network for connection among subscribers under the control of the same line concentration switch. CONSTITUTION:When a subscriber 1 delivers a call and the dial digits are transmitted, a central processor of an electronic exchange analyzes the dial digits to discriminate the terminal store position of a called subscriber. Then line concentration switches 7 and 8 are closed together with each switch within an exchange network 9 after confirming that the state of the network and the state of the called subscriber have no fault. Thus a talking link is formed. In case the called subscriber is identical with a subscriber 3 and the terminal of the called subscriber is stored in the same subscriber line concentration stage as the calling subscriber, the circuits of subscribers 1 and 2 are connected by a communication channel 10 via switches 7 and 8 after discriminating said case. In such a way, a channel is formed between the subscribers 1 and 2 with intervention of the network 9.

ーク側間は交絡通話路１０によって結合されてしる。In the figure, 1.2.3 is the subscriber connected to the same concentration switch, 4.5.6 is each subscriber circuit, 7 is the concentration switch from the subscriber side to the exchange network side, and 8 is the line connection switch from the exchange network side. A concentration switch 9 to the subscriber side is a switching network. The exchange network sides of the concentrator switches 7 and 8 are connected by a confounding communication path 10.

この交絡通話路の設備数は集線スイッチの規模により適
宜決定される。The number of facilities for this confounding communication path is appropriately determined depending on the scale of the concentrator switch.

ク９内の各スイッチを閉成して通話リンクを形成する。Now, when subscriber 1 makes a call and receives dialed digits, the central processing unit of the dangerous electronic exchange analyzes the dialed digits, determines the location of the called party's terminal, and connects the network. After confirming that the condition and the condition of the called party do not impede the connection, the concentrator switch 7.8 and each switch in the switching network 9 are closed to form a call link.

９を介することなしに完成する。If the called party is, for example, subscriber 3 and the called party's terminal accommodation position is accommodated in the same subscriber concentration stage as the calling party, this is determined, and the concentration switch 7.8 selects subscriber 1. The connection is made by a confounding channel 10, which is a circuit of .2. With this operation, the communication path between subscribers 1.2 is completed without passing through switching network 9.
