BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic switch, and more particularly, to a time switch and a time switch processor device of an electronic switch that enables a time switching process of a small amount of sub highway data at a low cost in a time switch device in which a subscriber device or a trunk line device is not matched. It is about.

1 is a block diagram of a time switch and a time switch processor device of a conventional electronic switch.

As shown, a time switch 30 implemented in redundancy in two-thirds of the size of the self 40 to time switch the 64 sub-highway data; Implemented in redundancy in the shelf 40 and the other shelf 50, the time switch 30 is configured as a time switch processor 70 for controlling the time switch 30 through a TD-BUS.

In the above, the time switch 30 multiplexes 32 sub-highway data and transfers the data to the first and second time switches 14 and 15, and the data transmitted from the first and second time switches 14 and 15. First and second multiplexing / demultiplexing units (10) (11) and first and second multiplexing / demultiplexing units (12) (13) for demultiplexing the data into 32 sub-highway data; Perform a time slot exchange function for data time switching from the first and second multiplexer / demultiplexer 10 and 11 and the first and second multiplexer / demultiplexer 12 and 13. First and second time switches 14 and 15 which interface with the first and second optical connectors 16 and 17; First and second optical connectors 16 and 17 for exchanging data with the first and second time switches 14 and 15 and connecting the space switch and the time switch 30 through an optical link; First and second large-capacity power supply units 18 and 19 for supplying power to all operations; The first and second multiplexing / demultiplexing units 10 and 11 and the first and second multiplexing / demultiplexing units 12 and 13, and the first and second time switches 14 and 15. ) And the switch back board 20 for accommodating the first and second optical connections 16 and 17 and the first and second large power supply units 18 and 19.

In addition, the time switch processor 70 may be implemented in a shelf 50 different from the shelf 40 on which the time switch 30 is mounted, and controls the time switch 30 through a TD-bus cable. Second time switch processor (60) (61); It consists of a processor backboard 62 which accommodates the first and second time switch processors 60 and 61.

The operation of the time switch and time switch processor device of the conventional all-electronic exchanger configured as described above is as follows.

First, the first boards 10, 11, 14, 16, 18, 60 of the redundant time switch and time switch processor operate in an active state and the second boards 12, 13, 15 In the case where (17) and (19) are in a standby state, the first multiplexer / demultiplexer 10 and the second multiplexer / demultiplexer 11 are 32-channel serial data groups having a transmission rate of 2.048 Mbps. When 32 sub highways are inputted, they are multiplexed into 8-bit parallel data having a transmission rate of 16.384 Mbps and transmitted to the first time switch 14.

Then, the first time switch 14 transmits the data received from the first multiplexer / demultiplexer 10 and the second multiplexer / demultiplexer 11 to the first time switch processor 60 in the time switch processor 70. The time slot is exchanged according to the control of the transmission to the transmission destination. At this time, the time switch 30 is implemented in two-thirds of the size of the shelf 40, and the time switch processor 70 is implemented in a shelf 50 different from the shelf 40 in which the switch processor 30 is implemented. Thus, the time switch processor 70 is connected to the time switch 30 and the TD-BUS cable to control the time switch 30 through the TD-BUS cable.

Then, the first optical connector 16 transmits the data in which the time switching operation is performed in the first time switch 14 to the spatial switch through the optical link, and is thus transmitted to the destination.

Next, the second boards 12, 13, 15, 17, 19 of the redundant time switch and time switch processor operate in an active state and the first boards 10, 11, 14 ( 16, 18 and 60 are in the standby state, the same as when the first boards 10, 11, 14, 16, 18 and 60 operate in the active state. It works in a way.

However, the time switch and the time switch processor device of such a conventional electronic switch are implemented in a self different from the time switch and the time switch processor so that the time switch processor controls the time switch through the TD-bus cable, There was a problem in that maintenance and management, such as failure to perform functions due to errors, became difficult.

In addition, by implementing the time switch to 2/3 of the size of the self, there was a problem that the space utilization rate is lowered.

In addition, since a large number of circuit packs must be supplied with power, a large capacity power supply unit must be used.

Disclosure of Invention An object of the present invention is to solve the conventional problems as described above. In particular, a time switch for time-switching small-capacity subhighway data and a time switch processor for controlling time-switching are implemented in a size of 1/2 of a self. The present invention provides a time switch and a time switch processor device of an all-electronic exchange that can improve the stability and maintenance of time switching of small-capacity sub highway data.

The present invention to achieve the above object,
