Abstract

PURPOSE:To dispense with complicated circuit and program used in an HDLC system and to accelerate the processing speed of a control part by performing the control of a speech path part by using a control channel of multiframe constitution. CONSTITUTION:A various kind of information from the speech path parts 3a-3n are always accumulated in a speech path information accumulation part 2. Therefore, the control part 1 can read out speech path information from the speech path information accumulation part 2 at need. Also, when the speech path parts 3a-3n are controlled, the control part 1 writes control information on the speech path information accumulation part 2, Thereby, the speech path information accumulation part 2 sends out written control information to the correspondent channel or frame of a correspondent speech path. Therefore, the speech path parts 3a-3n, when receiving information sent from the control part 1, can perform the control of the speech path part based on the control content of the information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic private branch exchange having a communication path section, and more particularly to a communication path information control system for controlling between a central control section and communication path sections.

[Conventional technology]

Conventionally, this type of channel information control system provides a control channel signal for controlling the channel section, and I{DLC
Insert a control signal to control the communication path using a signal method such as
It provided control between the central control unit and communication paths.

[Problem to be solved by the invention]

The conventional channel information control method described above is an HDLC method using a control channel signal, and therefore requires a lot of processing time for HDLC control. In addition, 1 {DL
Since a circuit for performing C control must be provided, there are drawbacks such as increased costs.

[Means to solve the problem]

The communication path information control system according to the present invention provides a control signal separately from the communication signal, and uses a multi-frame structured channel assigned to each communication path to send and receive control information between the control unit and the communication path. means for accumulating various types of information of a multi-frame structure sent from a communication path; and means for temporarily accumulating control information from a control unit and transmitting it to a corresponding channel of a corresponding frame of a designated communication path. It has

[Effect]

The present invention has a simple circuit configuration and can improve the processing speed of the control section.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the channel information control method according to the present invention. In the same figure, 1P control section,
2 is provided with means for accumulating various information of a multi-frame structure sent from the communication path, and means for temporarily accumulating control information from the control unit 1 and transmitting it to a designated communication path section to the corresponding channel of the corresponding frame. communication path information storage unit, 3a-3
Numerals 4, 5 and 6 are a reception signal line, a transmission signal line button and a multi-frame synchronization signal line, respectively.

Note that FIGS. 2(.) to 2(d) are diagrams showing, as an example, the structure of control signals in a 4-multi-7-frame configuration.
Figure (a) shows loop information composed of a multi-frame synchronization signal 7m, for example "1", and control information 7b.
b) is the lamp information composed of the multi-frame synchronization signal 8 & e.g. rOJ and control information 8b; D1 Fig. 2(c)
is relay information composed of a multi-frame synchronization signal 9a, for example rOJ, and control information 9b, and FIG.
This is alarm information configured from 0b.

Next, the operation of the channel information control system having the above configuration will be explained with reference to the example of 4 multi-frames shown in FIGS. 2(&) to 2(d). 1. Communication path section 3-3n
Various types of information are constantly stored in the channel information storage section 2 via the reception signal line 4. Therefore, when the control section 1 needs the communication path information, it can read the communication path information from the communication path information storage section 2. In addition, the communication path section 3
When controlling a to 3n, the control section 1 writes control information to the communication path information storage section 2. Therefore, the channel information storage section 2 sends out the written control information to the corresponding channel or frame of the corresponding channel.

For this reason, the communication path units 3a to 3n receive signals from the control unit 1. When the information received is received, the inside of the communication path section can be controlled according to the control content. In this way, since the control signals of the control unit 1 and communication path units 3 to 3n have a multi-frame configuration, for example, loop information is set in the channel of the first frame, control information, etc. is set in the channel of the second frame. In particular, different information can be set in each frame in the corresponding channel of each b1 frame. In this way, in the case of n multi-frame configuration, n types of control information can be transmitted and received.

〔Effect of the invention〕

As explained in detail above, the communication path information control method according to the present invention (1) uses a multi-7-frame control channel to control the communication path section, thereby eliminating the complexity of the 9S HDLC method. This has the advantage of eliminating the need for additional circuits and programs, and improving the processing speed of the control section.
