Abstract

PURPOSE:To obtain excellent delay characteristic while the burden of hardware is relieved by setting a multi-frame phase of an input signal together with information signal and a multiplex signaling at each line. CONSTITUTION:A signaling separation circuit 4 is separated and multiplexed as to all lines included in an input signal from the transmission line input signal 7 and the multi-frame signal for identifying the multiplex phase is fed to a line setting section 2. The line setting section 2 connects the sent information signal and the multiplex signaling and multi-frame signal in the same route and to predetermined transmission line transmission sections 5a-5c. Then signaling insertion circuits 6a-6c insert the multiplexed signaling from multiplex signaling paths 10a-10c based on a multi-frame signal from multi-frame paths 11a-11c to an information signal from information paths 9a-9c at each phase of transmission line sending sections 5a-5c and send them as output signals 8a-8c.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a line editing system that is created for the purpose of accommodating a transmission line in which a plurality of lines are multiplexed and efficiently operating the transmission line and lines. The present invention relates to a groove bottom method for equipment, and particularly relates to an intra-device transfer method for signaling, which is a control signal for each line.

[Conventional technology]

Signaling is usually a signal with a very small amount of information compared to information signals, but since there are many Wi-type signals, on a transmission path, it is multiplexed into a specific time slot identified by the multiframe signal of the transmission path. There is.

In the conventional IwIliil implementation fl, a method was used in which each type of signaling was separated into separate lines in the transmission path receiving section because of its simple configuration.

An example of this conventional signaling transfer method is shown in FIG. 2 and will be described.

In the figure, 1 is a line editing device, and this line editing device 1
, a transmission line receiving section 3 to which the transmission line input signal 7 is supplied, a line setting section 2 receiving the output of this transmission line receiving section 3 as input, and a transmission line transmitting section connected to the output side of this line setting section 2. It is composed of 4&Aba'C.

The signaling separation circuit 4 provided in the transmission line receiving section 3 separates all the MUs included in each line for all the lines included in the multiplexed transmission line input signal T.
Separate each signaling output type. Then, the information signal output from the transmission line receiving unit 3 and the signaling separated by type are connected to each line by the same route in the line setting unit 2, and the signaling insertion unit provided in each transmission line transmitting unit 5a*5bjc Connected to circuits 6a*6b*6e. And this signaling insertion circuit 6as
6b, 6cIIi, respectively, the output signal 8as of the transmission line
For all lines output as 8b*8c, all types of signaling are multiplexed again for each line in synchronization with a multi-frame signal determined for each transmission path and output together with the information signal.

In FIG. 2, 'ILJb*9e indicates an information path, and 12a-12bs12c indicates an individual signaling path.

FIG. 3 is a block diagram showing another example of the conventional signaling transfer method, and shows a method having a multi-frame circuit common to the entire device.

In FIG. 3, parts that are the same as those in FIG. 2 are designated by the same reference numerals, and their explanation will be omitted. 13a, 13b*13c are multiplexed signaling paths, and 14 is a multiframe generation circuit.

In FIG. 3, the output of the multi-frame generation circuit 14 is distributed as a common multi-frame phase to all transmission line receiving units 3 and transmission line transmitting units 5a, 5b*5c in the apparatus. Then, the signaling separation circuit 4 separates the signaling from the transmission line input signal T based on this multi-frame, writes it into a variable-tone backup memory (not shown), reads it out according to the multi-frame, and sends it to the line setting section 2. .

Here, the difference from the signaling transfer method shown in Figure 2 above is that the output phases of all the signaling separation circuits in the device are the same, so there is no need to use separate lines for each type of signaling, and multiplexing is possible. It is good that it remains as it is. This signaling output is then sent to multiplexed signaling paths 13a, 13b, 13c in the line setting section 2.
Otherwise, the transmission path transmitting unit 5a is transmitted through the same route as the information signal for each line.

5b and 5c, respectively. Also, the signaling insertion circuit 6a*6t)*6(! inserts multiplexed signaling into the information signal based on the common multi-frame phase and sends it out to the transmission path as an output signal 8aJb*8e.

[Problem that the invention seeks to solve]

In the above-mentioned signaling transfer method shown in FIG. 2, the transmission line receiving unit 3 separates the signaling into separate lines for each t* class, so when there are many 1it class of signaling, the capacity of the line setting unit 2 increases. However, there were problems in that the cost and hardware increased.

Furthermore, although the signaling transfer method shown in FIG. 3 described above is superior to the signaling transfer method shown in FIG. 2 in terms of hardware and air, the signaling included in the transmission line input signal T is There was a problem with the delay characteristics because it matched the multi-frame phase within the device, which is completely independent of the phase. In other words, the number of required signaling types varies depending on the line, and although the required multiframe period differs for each line,
The period of the multi-frame generation circuit 140 must be set to the maximum possible period. Therefore, even if the line has a short multi-frame period, the maximum delay will be the multi-frame period of the multi-frame generation circuit 14.

[Means for Solving the Problems] The signaling transfer method of the present invention has a signaling separation method in which the transmission line receiving unit separates the signaling of each line from the transmission line input signal while keeping it multiplexed, and outputs it simultaneously with multiframe No. 41. A signaling insertion circuit t-V which inserts multiplexed signaling into the information path of the multi-frame signal and outputs it as an output signal in the transmission path transmission section, and outputs the multiplexed signaling to the multi-frame signal to the output signal.

Each line has an information path, a multiplexed signaling path, and a multiframe path set to the same route.

[For production]

In the present invention, the multi-frame phase of the input signal is set for each line together with the information signal and multiplexed signaling.
