Abstract

PURPOSE:To allow a connection control processor to connect a trunk line to a nighttime direct extension, by setting the number information of a nighttime direct extension in a semifixed storage memory. CONSTITUTION:When an incoming signal from a trunk line 105 is detected by a signal control processor 100 after a nighttime-daytime state changeover switch 107 is operated to set a nighttime state, the processor 100 stores the incoming information in a temporary storage memory 109 and sends it to a connection control processor 101 through a common bus 102 between the processors. On receiving this information, the processor l01 makes the check that the changeover switch 107 is set at the nighttime side and when so, number information on a nighttime direct extension is read out of a semifixed storage memory 111 through a semifixed storage memory control circuit 110 to check the state of the nighttime direct extension; when it is ready to receive incoming, a channel switch 103 is controlled through a channel switch control bus 106 to connect the trunk line to the nighttime direct extension.

Description

[Detailed description of the invention] This 1JIF! , night call distribution system in automatic switching* KIII.

Conventionally, incoming calls at a switchboard were connected using one of the central office lines for answering and overloading.
If the station operator is not present during the call, one station is blocked to set it to night mode as a means of switching between day and night conditions. Therefore, if an incoming call is subsequently detected from outside, one of the central office lines is blocked and operations such as answering or forwarding cannot be performed from the extension line.
The changeover switch is separate from the exchange, and the extension telephone is W.
An IJK telephone is installed, and incoming calls are answered by directly connecting the YAPS to the telephone using an armpit changeover switch.

However, with this conventional method, when answering incoming calls at night, only a specific telephone can be used to answer calls, and it is also impossible to receive call forwarding or other services provided by automatic exchanges from this telephone. ), there is also the added benefit of having to prepare a special night telephone.

The present invention overcomes these shortcomings and allows a convenient night-time direct extension to be set as appropriate when a 10000aO relay stand operator is absent at night, and does not require a special night-time telephone. In other words, the present invention provides a night call distribution system in an automatic exchange 11 that can receive various services provided by an automatic exchange when receiving a call, and can appropriately distribute nighttime calls. - Or evaluation and connection control of a signal control program consisting of two or more processors.
In an automatic switching system using a distributed control system that performs exchange processing, an m-memory memory for storing incoming call information and a temporary memory memory for storing incoming call information and the above-mentioned temporary memory memory are provided. A means for writing and reading incoming call information is provided for each processor in the signal system group J4.
and a means for switching the state of the starry night, a semi-constant storage memory for storing number information of a night direct extension corresponding to the central office line, and means for reading the number information, such as the semi-permanent memory memo; means for reading and identifying the state of the nine night direct extensions;
When the day/night mode 1 switching means is operated, the night mode 1
For incoming calls that arrive at @11111 on 11, the above-mentioned overnight direct extension status identification qP is used to wall an internal message, and if the call can be received, it is distributed to the extension, and for incoming calls at night, It is possible to receive various services such as transfer and the like that can be provided by an automatic exchange.

The present invention will be explained below based on the implementation #llK shown in FIG.

Ill1llI is a block diagram showing an embodiment of the inter-flight incoming call distribution system of the present invention. As shown in the figure, the distribution method of the present invention is applied to the signal sg*p o-? /1100, **■gop47tuna 101, signal path 102 that separates both by 1 mm, overIHIxichi 103, inner@104 and office line tranter 105, and communication path switch control path 106.

In the nine automatic switchboards, the above-mentioned signal control presera tZoo K% day/night state changeover switch 107 and a temporary storage memory 109 are provided via the temporary storage control 1 circuit 10g, and A semi-permanent storage memory 111 is connected via a fixed storage memory control circuit 11o.

The signal system Kasumi Setsuna 100 is equipped with an incoming call detection means (not shown) as an input IIK, and controls the signals arriving from the nine devices connected to the communication path network and the sending of signals to the external aS. , Also, the connection system μRyu Tuna 101 sends the call network finll! based on the above-mentioned signal -- Glossena Zoo O incoming call information! Ill11 is performed 4, f4'jcl

Each of these processors Zoo 101 is configured as a Proryu Tuna group consisting of a plurality of processors. In this actual m-tsuba, each unit is configured with two units, but it may be configured with a larger number or with one unit.

The above signal W Gopu4 Senna 100K is temporary memory ■ll@
Means are provided for writing and reading incoming information into and from the temporary storage memory 109 via path 108.

This temporary memory memory 109Fi can be configured using a random access memory, but it is not limited to an external one, but may also be configured using a part of the IRo random access memory inside the signal control processor txoo. .

The semi-permanent storage memory 111 is, for example, a rewritable read-only memory, and stores night direct line mO number information corresponding to the central office line. This number information is set in advance (but can be changed if necessary).

The above taam * process? 101K denotes a means for reading the number information of the night direct extension stored in the semi-permanent storage memory 111 via the semi-permanent storage memory control path IIa 110, and a means for reading the number information of the night direct extension stored in the memory 111; It is also possible to provide means for identifying the state of the vehicle.

Next, the operation of the distribution system of the present invention will be explained based on the above configuration.

When the signal control processor 100 detects an incoming signal from the station 11105 after switching to the nighttime state by operating the day/night state changeover switch 107 at night, the processor 10G stores the incoming call information in a temporary memory 109. At the same time, it is transmitted to the contact hardware controller 101K via the common path 102 between the controllers. When the connection control program 101 receives this information, it checks whether the changeover switch 10γ is in the nighttime state, and if it is in the nighttime state, it switches the semi-permanent memory to the semi-permanent memory via the semi-permanent memory control circuit 11G. Read the number information of the night direct extension from 111, check the status of the read night direct extension,
If the call can be received, the call path switch 103 is controlled via the call path switch control path 106 to connect to the night direct extension. In this case, if the direct extension at night is busy or unable to receive calls, it is possible to use the various services provided by the automatic exchange and have the call received by another office 11.

It should be noted that, as mentioned above, the overnight direct extension can be easily changed since it is easy to change the semi-permanent storage memory 111, so any extension can be designated according to the FK.

As mentioned above, the originating WA sets the night direct extension number information in the semi-permanent storage memory, and based on this information, connects the i! Due to the configuration in which the control processor controls the connection of the office line to the night-time direct extension, the night-time direct extension can be set as appropriate without the need for a Sobetsu night telephone when the operator is absent at night or on holidays. Furthermore, when receiving a call, it is possible to receive various services such as transfer provided by the automatic exchange, and it is possible to appropriately distribute night-time calls.
