Abstract

PURPOSE:To use a remaining time slot for communication by allocating the time slot only to a high speed line, for which it is necessary to extend a control path, out of the plural high speed lines to be composed of plural multiplexing devices. CONSTITUTION:Multiplexing devices 1-4 are connected with transmission lines 6-9 as shown in the figure and high speed line terminals 101, 102-401 and 402 are provided in the multiplexing devices 1-4. A supervising device 5, which is in the same place as the multiplexing device 2, allocates the suitable time slot to the necessary multiplexing device intervals 2-1-3 and 2-4 by control paths 10, 11 and 12. Since it is not necessary to allocate the control path to the multiplexing device 3-4 interval, the time slot is used for communication. Thus, communication efficiency is improved and a service is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control path allocation method between multiplexing devices, and particularly to a control path allocation method when a multiplexing device has a plurality of high-speed lines.

[Conventional technology]

Conventionally, in this type of control path allocation method, when a multiplexer has multiple high-speed lines, a control path is allocated to all the lines without determining whether a control path is necessary.

[Problem to be solved by the invention]

The conventional control path allocation method has a problem in that, in a multiplexing device having a plurality of high-speed lines as described above, unnecessary control paths are also allocated as time slots, resulting in a reduction in transmission efficiency.

The present invention is an attempt to solve these problems of the conventional method, and provides a method for allocating control paths between multiplexing devices without reducing transmission efficiency.

[Failure to solve the problem]

The patented path allocation method is characterized in that time slots are allocated to high-speed lines that need to constitute a control path, and no time slots are allocated to high-speed lines that do not need to constitute a control path. It will be done.

〔Example〕

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

FIG. 1 shows a configuration diagram of an embodiment of the present invention.

In this figure, multiplexer 1 and multiplexer 2 are connected to transmission line 6. The multiplexer 1 and the multiplexer 3 are connected to a transmission line 7. The multiplexing device 3 and the multiplexing device 4 are connected through a transmission path 9, and the multiplexing device 2 and the multiplexing device 4 are connected through a transmission path 8 to form a network. The monitoring device 5 is located at the same location where the multiplexer 2 is set up and has a control path 10° to the multiplexer 1 and a control path 11 to the multiplexer 3. A control path 12 to the multiplexing device 4 provides a monitoring path. In this case, a control path between the multiplexing device 3 and the multiplexing device 4 is not provided because it is not necessary to extend the control path.

As each control path, it is necessary to allocate a time slot with a communication speed of 2.4 kb/s to each multiplexer, and the multiplexer 1 has a high-speed line 101 and a high-speed line 102.
Communication speed 2.4. kb/s
The multiplexer 2 allocates time slots for the high-speed line 201 and the high-speed line 202 . Multiplexer 3 is high-speed line 3
01. Multiplexer 4 (l'i: time slots with communication speeds of 2 and 4. kb/s are allocated as control paths to high-speed line 401, respectively.

Here, the high-speed line 302 of the multiplexer 3 and the multiplexer 4
Since the high-speed line 402 requires a control path, the communication speed is 2.4. I can't get a kb/s time slot. Therefore, during this period, the communication speed for the control path is 2.
．． A 4 kb/s time slot can be used for communication.

〔Effect of the invention〕

As explained above, in the present invention, among the plurality of high-speed lines of one multiplexing device, a time slot for a control path is not allocated to a high-speed line that does not require a control path. Since it can be used for communication, the transmission efficiency for normal communication data can be increased, and service can be improved.
