Abstract

PURPOSE:To eliminate the labor for the special number operation of an extension and to surely change a reception destination by discriminating the day and the night of an incoming tenant at every number unit fed from a remote station, converting into another numbers respectively corresponding to preset incoming numbers and connecting it. CONSTITUTION:The incoming of a call is present in a trunk, the number from the remote station is sent and a numerical character is completely received, then, a tenant day/night information memory is referred initially, and the day and the night of the incoming tenant are discriminated. If the incoming tenant is in the daytime, from the pointer of the daytime, and if it is at night, from the pointer of the night, an incoming number converting memory is sequentially developed in the route of the reception trunk, initially. Then, based on the read number, an exchange processing is progressed. For instance when the dial number of the number of 2,000 is sent as an extension number from the remote station, the connection is performed to the extension STN-A of the number of 2,000 in the daytime and to the extension STN-B of the number of 2,500 at night.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a called number conversion system in a storage program type electronic exchange.

[Conventional technology]

Traditionally, this type of called number conversion method involves adding/adding the called number.
It was supposed to be converted to a single different number using methods such as deletion.

[Problem that the invention seeks to solve]

The above-mentioned conventional called number conversion method has a drawback in that it simply converts to one number, but cannot convert to different numbers for day and night.

[Means for solving problems]

The incoming call number conversion method of the present invention includes a tenant day/night information memory that stores day/night information indicating whether the tenant is currently in the daytime or nighttime time zone for each tenant; It has an incoming number conversion memory to convert to a different number in response to nighttime hours, and when a call arrives at the trunk, a number is sent from the game player, and the number reception is complete.
Refer to the first memory to identify the daytime/nighttime of the incoming tenant, expand the incoming number conversion memory with the route of the incoming trunk, and then expand it with the number sent from the opponent to find the number to be converted. have the means.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 are block diagrams of a tenant day/night information memory and a called number conversion memory, respectively, which constitute an embodiment of the called number conversion method of the present invention.

Each tenant T is stored in the tenant day/night information memory (Figure 1).
No., TN+, "・, TNn-+, TN currently stores day/night information of "1" if it is daytime and "0" if it is nighttime, and this is based on the tenant index and The 0M signal conversion memory (FIG. 2) accessed by the tenant even/odd index is used to convert the number sent from the opponent to a different number corresponding to the daytime/nighttime time zone. In the figure, various miscellaneous information is stored in the flag part, the number of digits after number conversion is stored in SDR, and the number after conversion is stored in DCo-Dfl;n.

When a call arrives at the trunk and a number is sent from the opponent's office and reception of the numbers is complete, the tenant day/night information memory is first referenced to identify the day/night of the incoming tenant. If the incoming tenant is daytime, use the daytime pointer, if it's nighttime, start with the night pointer, and then expand the incoming number conversion memory in order through the incoming trunk route, and then the number sent from the opponent.
Finally, since the number to be converted is found, the exchange process is subsequently carried out based on this read number instead of the received number. Note that if an exchange number is actually registered in this table but fails to be expanded, the number received from the game is expanded as is.

3 to 5 show actual examples using this called number conversion method.

Figure 3 shows that when a player sends the extension number 2000 and dial digits, during the daytime (indicated by ■ in the figure, the same applies hereinafter), the number 2000, extension 5TN-A, is dialed at night (indicated by ■ in the figure). (hereinafter the same) is number 2500 extension 5TN-
8 is shown. Similarly, FIGS. 4A and 4B show a case in which connection is made to extension number 2000 STH during the daytime and to a relay stand or night transfer stand ATT during the nighttime. Figure 5 also shows tandem calls during the day and extension STN number 2500 at night.
The following shows how to connect to each.

〔Effect of the invention〕

As explained above, the present invention identifies the day and night of the incoming tenant in units of numbers sent from the opponent, converts each incoming call number to a different number corresponding to the preset incoming number, and connects the trunk. For example, an incoming call can be connected to an office extension during the day, and to a guardhouse extension or a night forwarding desk at night, without the need for the extension caller to set call forwarding, etc. This has the effect of saving you the trouble of operating special numbers and allowing you to reliably change the destination of your calls.

Claims (1)

[Scope of Claim] A storage program type electronic exchange includes: a tenant day/night information memory that stores day/night information indicating whether the tenant is currently in the daytime or nighttime time zone for each tenant; It has an incoming number conversion memory to convert the number to a different number depending on the daytime/nighttime time zone, and a tenant day/night information memory when a call arrives at the trunk and the number is sent from the game and the number reception is complete. A terminating number that has a means of referencing to identify the daytime/nighttime of the terminating tenant, expanding the terminating number conversion memory along the route of the incoming trunk, and then expanding it with the number sent from the opponent to determine the number to be converted. Conversion method.
