Abstract

PURPOSE:To use a same time division switch for a 24-channel voice signal or a signal other than the voice signal and to set a line by using a signal format including a 7th block storing additional information of a time slot location corresponding to a data of each channel of 6 blocks subject to multiplex processing. CONSTITUTION:A 7th block BLOCK 7 storing additional information of a time slot position corresponding to a data of each channel is included to a multiplex format in which 6 channel signals are arranged scatteringly to time slot locations BLOCKs 1-6 corresponding to 6 blocks respectively. That is, number of the blocks is increased by one as 7 blocks and the signal is handled, then all data of 24ch+alpha are accommodated and line setting of 24ch+alpha ways is attained. Then the operation of a time division switch is made identical. Thus, the line setting of 24ch+alpha is attained by the line setting by, e. g. 4 handling groups (24 channels).

ジタル伝送方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a digital transmission system, and particularly to a digital transmission system that uses a transmission format for line setup using a time division switch.

ある。Conventional digital transmission systems use a format in which a 24 channel (ch) x N signal is divided into 6 blocks, as shown in Figure 2, for example, as a signal format for line setup using a time division switch. . According to this format, by making the time division switch perform the same operation in each block, it is possible to set lines in units of 6 channels.

線設定を行わなければならないという欠点がある。In the conventional digital transmission system described above, the 6-block format poses no problem if it only handles 24ch audio signals, but for example, when setting up a line for 24ch+α signals, this format accommodates all data. I can't. Another disadvantage is that when setting up a line using this format, the status bit (ST) containing side ringing data is handled at the same time, so it is necessary to add an additional lbit to the signal bit and set up the line using a time division switch. There is.

を特徴とする。In the digital transmission system of the present invention, data for six channels of multiplexed digital signals are collectively handled as one handling group, so the signals of the six channels are placed in time slot positions corresponding to each of the six blocks. The distributed multiplex format is characterized by including a seventh block that stores additional information of time slot positions corresponding to data of each channel being multiplexed.

ロック含んで構成される。The transmission signal format of this embodiment handles data for 6 channels of multiplexed digital signals as one handling group (HG), so 6 channels of signals correspond to each of 6 blocks (BLOC1 to 6). In a multiplexed format distributed at time slot positions, it is configured to include a seventh Ulock that stores additional information at time slot positions corresponding to the multiplexed data of each channel.

みで回線設定をすることができる。In this way, all the data of 24ch+α can be accommodated by increasing the number of blocks by one and handling the signals as 7 blocks, making it possible to set up a line of 24ch+α. Moreover, it is possible to make the operation of the time division switch the same in each block, for example, 48G (2
By setting up a line for 4ch), you can set up a line for 24ch+α. Also, add status bit S to this increased block.
Since T can be input, line settings can be made for both conventional 24ch audio signals and 0.3MHz bulk data signals by simply changing the contents of the control memory using the same time division switch.

This has the advantage that the same time division switch can be used to set up lines for signals other than signals and audio.
