JPH05103098A - Priority subscriber interrupt system for private branch exchange - Google Patents

Abstract

PURPOSE:To decide whether or not a call is to be connected when an opposite party is busy depending on the priority class by providing the priority class number to subscribers. CONSTITUTION:Suppose that a subscriber A being a caller subscriber 13 of a caller station 11 makes dialing of a subscriber number of a subscriber B being a called subscriber 14 which the subscribers B, C being the called subscribers 14 of a called station 12 are speaking, then the caller station 11 provides a priority class number of the subscriber A being the caller subscriber 13 to a subscriber number of the subscriber B being the called subscriber 14. Then the called station 12 receives the priority class of the subscriber B number being the called station subscriber 14 and the subscriber A being the caller subscriber 13. Since the subscriber B being the called station subscriber 14 is speaking, the called station 12 compares the priority class number of the subscriber B with the priority class number of the subscriber of the caller station 11 and compares a host class number with the priority class number of the subscriber of the caller station 11. When the priority class of the subscriber A of the caller station 11 is higher than that of the subscribers B, C of the called station 12, the called station 12 sends an interrupt tone to the subscriber B.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a priority subscriber interrupt system for a private branch exchange, and more particularly to a priority subscriber interrupt system for a private branch exchange in which a priority class is set for each subscriber of the private branch exchange to perform interrupt connection.

[0002]

BACKGROUND OF THE INVENTION Conventional private branch exchanges do not provide priority classes for subscribers.

[0003]

However, this conventional private branch exchange has a problem that it is not possible to interrupt by the priority class because no priority class is provided for the subscriber.

[0004]

The private branch exchange priority subscriber interruption system of the present invention sets a priority class for each subscriber of a private branch exchange, and also sets a higher priority class for the called subscriber and the other subscriber and the calling subscriber. A comparison means for comparing the priority classes is provided, and even if the called subscriber is busy, the priority classes of the calling subscriber and the calling subscriber are compared with the priority classes of the calling subscriber and the calling subscriber to compare the priority classes of the calling subscriber with each other. The connection is prioritized.

[0005]

According to the present invention, the subscriber is provided with a priority class to make a decision as to whether or not to make an interrupt connection.

[0006]

1 is a block diagram showing an embodiment of the present invention. In FIG. 1, 11 is a transmitting station and 12 is a receiving station. Reference numeral 13 indicates a calling subscriber, and 14 indicates a receiving subscriber. Then, each subscriber of the private branch exchange is provided with a priority class, and a comparison means for comparing the higher priority class of the called subscriber and the other subscriber with the priority class of the calling subscriber is provided, and the called subscriber is busy. However, the priority classes of the called subscriber and the partner subscriber are compared with the priority classes of the calling subscriber and the connection of the higher subscriber is prioritized.

Next, the operation of the embodiment shown in FIG. 1 will be described. First, the A subscriber of the originating subscriber 13 of the originating station 11 dials the B subscriber number of the terminating subscriber 14 while the B subscriber and the C subscriber of the terminating subscriber 12 of the terminating station 12 are talking. Then, the calling station 11 assigns the priority class number of the A subscriber of the calling subscriber 13 to the B subscriber number of the called subscriber 14. Next, the receiving station 12 receives the B subscriber number of the receiving subscriber 14 and the priority class of the A subscriber of the originating subscriber 13. The called station 12 is the called station subscriber 1
Since the B subscriber of 4 is busy, the priority class number of this B subscriber and the priority class of the other C subscriber are compared,
The higher class number and the priority class number of the subscriber A of the transmitting station 11 are compared.

Then, the subscriber A of the originating station 11 is
When the priority class is higher than the B subscriber and the C subscriber of No. 2, the terminating station 12 sends an interruption tone to the B subscriber. The subscriber B of the terminating station 12 knows that the priority class is higher than this by the interruption sound, and by hooking, the terminating station 12 sends a response signal to the originating station 11 to establish a call state. When the priority class of the subscriber A of the originating station 11 is lower, the receiving station 12 sends a busy tone to the originating station 11.

FIG. 2 is an explanatory diagram showing an example of connection provided for explaining the operation of FIG. In FIG. 2, (a) shows the higher order of the calling subscriber priority class, and (b) shows the calling subscriber priority class. A cross indicates that the calling subscriber 3 does not connect because it is on the same level as or lower than the priority class of the calling subscriber, and a circle indicates that the calling subscriber 3 is higher than the priority class of the calling subscriber. , Indicates that an interrupt connection is made.

As described above, by providing the subscriber with the priority class number, it is possible to determine whether or not to connect during the other party according to the priority class.

[0011]

As described above, according to the present invention, the priority class is set for the subscriber and it is determined whether the interrupt connection is performed or not. Therefore, a call from the user or a person higher than the other party in the company is made. It has the effect of not interrupting higher-ranking people.
