が得られる。 According to the present invention, a remote station consisting of a concentrator switch accommodated in a subscriber line time division switch serving as a master station,
In this method, communication between both stations is carried out from the master station via a PCM transmission line, and multiple PCM transmission lines are installed, and a 30-channel encoder/decoder is installed on the output side of the remote station's concentrator switch. A multiplexing circuit for multiplexing a plurality of encoders/decoders, and a demultiplexing circuit for distributing the multiplexed signals to multiple PCM transmission lines are provided. , the separation circuit allows each channel of each encoder/decoder to be distributed equally to each transmission line, so that even if a line failure occurs in one transmission line, the connection between the channels of each encoder/decoder and the master station can be made through the remaining transmission line. The second reason is that the demultiplexing circuit is designed to be a 32-channel system without interfering with the transmission and reception of control signals between remote stations and communication between remote stations.
By configuring the channel so that it can be distributed evenly to either the PCM transmission line or the 24-channel system PCM transmission line, it is possible to use either 32 channels or 24 channels.
A remote station control system is obtained which is characterized in that it can also be interfaced with a PCM transmission line.

MUX and DMUX indicate multiplexing circuits necessary for the present invention. Also, M is the number of concentration switch groups (number of CODECs),
M' indicates the number of PCM transmission lines. In this example,
To simplify the explanation, we will explain the multiplexing and demultiplexing of signals in the upstream direction from the CODEC that interfaces to the 30-channel PCM transmission line toward the master station. In this case, M=M'. Also, CODEC is A-

るように多重分離してCODECに入力される。 The uplink signals of M CODECs are multiplexed in the MUX section, and the multiplexed signals are sent to each DMUX section.
Demultiplexing is performed so that the output of the CODEC is evenly distributed to M transmission paths. In other words, if M = 3, CODEC #1 has 30/M = 10 channels (No. 1 to No. 10). channel), CODEC#2 30/
M=10 channels (No.1 to No.10 channels) CODEC
30/M = 10 channels of #3 (No.1 to No.10 channels) are assigned to the #1 transmission path, channels 11 to 20 of each CODEC output are assigned to the #2 transmission path, and channels 21 to 30 of each CODEC output are assigned to the #2 transmission path. is demultiplexed so as to be assigned to transmission line #3. By doing this, even if one transmission path becomes a failure, control of subscribers accommodated in each LSW and communication of calls can be performed via the remaining transmission path. For downlink signals, under the control of the master station, channels are allocated to each transmission path in the manner described above.
The signals are multiplexed in the DMUX section, demultiplexed in the MUX section so as to correspond to each CODEC, and then input to the CODEC.

することが可能となる。 On the other hand, when interfacing to a 24-channel transmission line, for example, if M = 3, M' = 4, and each CODEC 30/4 (appropriately converted to an integer) must be distributed to 4 transmission lines as described above. Bye. In this way, without changing the number of outgoing lines of the line concentration switch,
It can be used for both 32-channel and 24-channel PCM transmission line systems.

In the case of a time division concentrator switch, the encoder/decoder is located between the subscriber circuit and the concentrator switch, and the multiplexing and demultiplexing methods can be performed in exactly the same way. Therefore, the method of the present invention is applicable to all remote control methods such as those using a concentrator switch.
