Abstract

PURPOSE:To reduce the service load on a transfer board operator and to improve the service to an office subscribers by performing switching to a teleguide device when call congestion occurs or when an answer waiting time becomes long during incoming to the trunk-line. CONSTITUTION:When incoming to the trunk-line is detected in nighttime, a central controller 2 reads the number (n) of incoming calls up to the incoming out of a storage device 5 to calculate the total number (n+1) of incoming calls. The number (n+1) is compared with a specific permissible value N stored in the device 5; when (N+1)>N, a DR relay of a switching driving circuit is operated to make a contact dr, and a T relay 4 is operated to operate a contact (t), making a connection with the teleguide device 3. Then, when (n+1)<=N, an incoming answer timer is monitored to compare a time (t) required for answering with a permissible value T stored in the device 5; when t>T, switching to the device 3 is performed following a similar procedure.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer switching system for an automatic switching system, and a transfer switching system for a load stacking program allocation type switching system.

In the conventional night transfer switching system, night transfer is carried out when the relay desk operator in the first section of the station finishes his work, and after switching, the number of station line personnel is generally restricted, and the night transfer desk operator is responsible for responding to incoming calls on the central office line. This is the method of execution. In this system, immediately after night switching or in an emergency, the number of incoming calls to the central office line increases, and response times become slow, deteriorating service to central office subscribers and increasing the workload on night transfer desk operators. It was happening.

The present invention eliminates the above-mentioned drawbacks and, for example, when an incoming call to the central office line is received after being transferred at night, or when the transfer operator does not respond after a certain period of time, the telephone operator switches to the teleguide device and the central office line subscriber receives an incoming call. This provides a method that makes it possible to send messages to other people.

According to the present invention, in an exchange using the storage program i+JIJ, there is provided a storage device for storing permitted incoming calls to the central office and a response waiting time for incoming calls to the central office, a teleguide device for sending messages to central office line subscribers, and the teleguide. Equipped with a switching circuit to the device, at the station @ 1 line.

If the number of calls exceeds the allowable number of calls, or if the waiting time for incoming calls on the central office line exceeds the waiting time, the switching circuit switches to the teleguide device and sends a message to the central office line subscriber. A forwarding switching method for automatic switching equipment is obtained.

An embodiment of the present invention will be briefly described with reference to FIG.

FIG. 1 is a schematic diagram of one embodiment of the present invention. In FIG.
CICTn or CBWTO-CHWTn), teleguide ('
■゛・G) 3 switching circuit 4 is connected, and normally the connection is in the state shown by the dotted line.

First, when an incoming call is detected at night using a well-known method, the central controller t(CC)z reads the number of incoming calls n up to the time of the incoming call from the memory device (M) 5, and calculates the total number of incoming calls n+1. calculate. This value n+1 and the constant allowance lIl stored in advance in the storage device 5! If n+1>, the iJRυ relay corresponding to the incoming trunk of the switching drive circuit 6 shown in FIG. 1 is operated. Due to the operation of the V relay, the dr contact becomes (JN), and the relay is activated.Therefore, the t contact is activated and connected to the teleguide devices T and G.

Next, in the state to n+1<, general incoming call processing is performed. In this case, monitor the incoming call response timer and record the time required for response in the storage device M. t>
In the case of T, switch to the teleguide device using the same procedure as above.

In the above embodiments, switching transfer at night was explained.
The present invention can be applied not only at night.

As explained above, this button light allows the operator of the transfer station to switch to the teleguide device when a call is received on the central office line, and when the call is hidden or when the waiting time for a response becomes long. This has the effect of reducing business negative impacts and improving services for station subscribers.
