Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pick-up group expansion method for an automatic switchboard having pick-up services.

The pick-up service is a service that allows a call received within the same group to be changed to your own phone by lifting up the handset of the phone other than the one currently receiving the call and dialing the pick-up special number.

Conventionally, pick-up groups have been the same day and night, so when there are not many people, such as at night, it may be necessary to answer an extension that cannot be picked up. At this time, if the incoming extension is far away, the calling party is forced to wait until the answerer arrives at the incoming extension, and the answerer is also forced to move to the incoming extension. Be strong.

An object of the present invention is to expand the number of extensions that allow pick-up service by externally specifying information to the control device of the switch, such as night switching information from the switchboard, and to create a new pick-up group that enables pick-up over a wider area. This method provides an enlargement method.

According to the present invention, the present invention provides a private branch exchange having a pick-up service for changing the destination of calls to one's own telephone, which has one pick-up group table and another pick-up group table in the main memory, and By changing the number of extensions covered by the pick-up service by expanding or reducing the number of reference tables of the plurality of pick-up group tables based on specified information for the control device, such as night switching information, etc. achieved.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the pick-up group expansion method according to the present invention. FIG. 1 is a diagram of a relay system for pick-up services during the daytime, and FIG. 2 is a diagram of a relay system for pick-up services during nighttime hours. be.

In Fig. 1, A, B, and C are extension telephones;
NW is network, CC is central control unit, BTT
is a visit tone trunk, and TRK is a local trunk.
or leased line trunk, etc., DPT is a daytime pick-up group table, NPT is a night-time pick-up group table, RGT is a linking trunk,
MM indicates main memory.

Now, if extension C receives an incoming call via the trunk (TRK), when extension A picks up, the central controller CC detects the call from extension A and stores it in the daytime pick-up group table in main memory MM. See DPT. However, since only the incoming calls to extension telephones A and B are written in the daytime pick-up group table DPT, there are no incoming calls, and a busy tone is sent to extension A. On the other hand, the connection state of the pickup service during night time will be explained with reference to FIG. The same reference numerals shown in FIG. 2 as those shown in FIG. 1 indicate the same contents. Upon receiving the night switching information, the central controller CC checks the extensions in the daytime pick-up group table DPT in the main storage, and also checks whether or not an extension is receiving an incoming call in the night-time pick-up group table NPT. For this reason, when extension A goes off-hook for an incoming call to extension C, the central controller CC reads extension C written in the night pick-up group table NPT, and allows extension A to pick up the incoming call to C. becomes possible.

Note that 1 on the connection route on the network indicates that a call is being received to C, and 2 indicates that the call can be picked up and the destination of the call has been switched.

As explained above, according to the present invention, the pick-up service can be freely switched according to the situation in the office, and the functions of the pick-up service can be effectively expanded, which has a very large effect on the user.

Claims (1)

[Scope of Claims] 1. In a private branch exchange having a pick-up service for changing the destination of a call to one's own telephone, a plurality of pick-up tables are provided in the main storage device, and each pick-up table constitutes a pick-up group with a different range. By transmitting the pick-up group range designation information to the control device, the control device selects the pick-up table to be referred to and selects the extension number to be used for the pick-up service. A pick-up group expansion method characterized by changing the number. Tem.
