TECHNICAL FIELD OF THE INVENTION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchanger, and more particularly, to a digital basic rate subscriber block having a collection function and a call processing function.

ISDN (Integrated Service Digital Network) is a communication network that integrates existing voice and non-voice services and is generally called an integrated information network. A typical characteristic of ISDN is that the subscriber and the communication network are connected by a single line, and that the network is composed of digital, and that the voice and non-voice services can be integrated and processed on this basis. In ISDN, both circuit switching and packet switching are possible at the same time. It provides a common connection point for existing circuit switching network and packet switching network, enables sharing of various information resources in communication network, various information processing and communication processing, There is an advantage that it can be facilitated.

However, in the structure of the ISDN exchange developed up to now, there is a problem that the hardware configuration is complicated because a plurality of processors share a role to perform call processing and switch control of subscribers.

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a system and method for controlling a subscriber station, The purpose is to provide a subscriber block.

The digital basic rate subscriber block according to the present invention is a general information communication and subscriber processing device of an all-electronic exchange. The subscriber block receives B channel and D channel information from a subscriber and aggregates B channel and D channel information BRI, which outputs to the device matching line and the L bus, and BRI, an aggregator matching circuit and an L bus, and is configured to be duplexed with the BRI to output B channel information in the sub highway state, and to transmit the D channel information to the PCM bus First and second subscriber controllers each having a call processing function and an aggregation function; first and second switches for switching and outputting B channel information from a subscriber controller according to a predetermined control signal; And outputting a control signal for controlling the circuit switching of the first and second switches according to the applied D channel information; and a processor for matching the D channel information with the processor from the first and second subscriber controllers, And a matching device for applying a voltage to the electrodes.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a digital basic rate subscriber block having a collection and call processing function according to the present invention. The subscriber processing unit 1 includes a plurality of basic rate access interfaces (hereinafter referred to as BRIs) T0-T31, which are connected to the subscriber controllers C1 and C2 via the L bus, respectively. Here, subscriber controllers C1 and C2 are configured for redundancy with BRIs (T0-T15) and (T16-31).

Here, the BRIs (T0 to T31) have a basic connection function with the subscriber line (2B + D), a separation function between the B channel and the D channel, a connection function with the L bus, And the B channel is applied to the subscriber controllers C1 and C2 using the concentrator matching line, respectively.

Here, the B channel is a typical information channel and has a speed of 64 Kbps, so that the user can freely transmit information, and the representative information in the exchange will be voice.

Also, the D channel is called a signal channel, and has a speed of 16 Kbps for exchange control of information channels. An example of such a D channel would be information such as a telephone number.

Subscriber controllers (C1, C2) receiving information on the D channel and the B channel transmit the D channel information through the PCM bus to the PCM matching devices (10-1, 10-2), and the B channel information through the sub highway (20-1, 20-2).

Here, the PCM bus divides the data to be transmitted and received in a time slot format and transmits the data. The method of time slotting the data is described in detail in "Processor and Device Communication Device It will be easy to know.

That is, the subscriber controllers C1 and C2 time-slot the D channel information of the BRI (T0-T31) to apply to the matching devices 10-1 and 10-2 via the PCM bus, and the matching devices 10-1, 10-2 apply the D channel information to the processors P1 and P2, respectively.

It is to be understood that the two processors P1 and P2 and the matching devices 10-1 and 10-2 are for redundancy with the subscriber controllers C1 and C2, Those who have it will know easily.

As described above, the D channel information is information for channel exchange of B channel information, and the switches 20-1 and 20-2 are switch parts where circuit switching of the B channel is practically performed, And is controlled by the processors P1 and P2.

That is, the processors P1 and P2 control the switching of the switches 20-1 and 20-2 according to the D channel information provided by the subscriber controllers C1 and C2, The B channel data of the BRI (T0-T31) provided to the base station can be switched as the corresponding line.

Here, the B channel data provided to the switches 20-1 and 20-2 are primarily collected through the subscriber controller concentrator and the population ratio can be varied.

That is, in the present invention, the subscriber controllers C1 and C2 have functions of applying time-slotted data of the L bus to the processors P1 and P2 and the switches 20-1 and 20-2 via the PCM bus, It is possible to perform a call processing function and a collecting function in addition to the above, thereby reducing the load on the processors P1 and P2. Accordingly, it can be seen that the multiple processors of the existing structure can be integrated into one processor as the load of the processors P1 and P2 is reduced.

As described above, according to the present invention, the subscriber control unit configured to perform a call processing function and a collecting function in the subscriber processing apparatus can be integrated into one processor.
