Description

How to increase internal line capacity in integrated service system

The present invention relates to an integrated service system, and more particularly, to a method for increasing internal line capacity in an integrated service system.

Hereinafter, the integrated service system according to the related art will be described with reference to the accompanying drawings.

1 is a diagram illustrating an integrated service system according to the prior art, which is input to a T1, E1 and an analog trunk through a Public Switching Telephone Network (hereinafter referred to as PSTN) 1 and the PSTN 1; A plurality of trunk interface boards (2a to 2n) for interfacing the PCM data to be transmitted (hereinafter referred to as TIB) (2a ~ 2n), and transmitted from the plurality of TIB (2a ~ 2n) via a highway bus to 32 channels Digital Switching Board (hereinafter, abbreviated as DSB) 3 for switching typed PCM data according to a control signal, and a signal process board for processing signals switched by the DSB 3 (Siganl Process). Board (hereinafter abbreviated as SPB) (4) and a plurality of Voice Process Boards (VPBs) for converting PCM data switched through the highway bus from the DSB 3 to ADPCM data. 5a to 5n, and a fax process board (hereinafter referred to as FPB) for converting PCM data switched over the highway bus from the DSB 3 to the 32 channel into fax data (6) And an Internet Phone Board (hereinafter referred to as IPB) 7 for converting PCM data switched through the highway bus from the DSB 3 to 32 channels into Internet phone data (7), and the overall operation of the block. And a main process board (hereinafter abbreviated as MPB) 8 for controlling the overall operation, and a memory 9 for storing the ADPCM data and the fax data according to the control signal of the MPB 8. .

The integrated service system according to the related art configured as described above will be described in detail with reference to the accompanying drawings.

First, when a subscriber makes a call through the PSTN 1 for voice, fax, or Internet phone service, a plurality of TIBs 2a to 2n are connected to signals input to the T1, E1 and analog trunks through the PSTN 1. Accordingly, the MPB 8 reports that the signal has been input, and then interfaces with the highway bus.

The MPB 8 then outputs a control signal for switching it to the SPB 4 according to the signals input from the plurality of TIBs 2a to 2n.

Accordingly, the DSB 3 switches signals transmitted from the plurality of TIBs 2a to 2n through the highway bus to the SPB 4 according to the control signals of the MPB 8.

The SPB 4 then signals the signal switched by the DSB 3 and reports the result to the MPB 8.

Accordingly, the MPB 8 outputs a control signal for switching the PCM data by type according to the result reported by the DSB 3.

The DSB 3 then sorts the PCM data transmitted from the plurality of TIBs 2a to 2n through the highway bus according to the control signal of the MPB 8 for each type (Voice Message Service, Fax Message Service, Internet Phone Service). Switch to multiple VPBs 5a-5n, FPB 6 or IPB 7.

Then, a plurality of VPBs 5a to 5n convert the PCM data switched through the highway bus from the DSB 3 into the ADPCM data and store them in the memory 9 through the MPB 8.

That is, a plurality of VPBs 5a to 5n convert the 64 kbps PCM data into 32 kbps ADPCM data and transmit the same through the parallel bus.

The MPB 8 then stores the ADPCM data of the plurality of VPBs 5a-5n in the memory 9.

In addition, the FPB 6 converts the PCM data switched over the highway bus into the 32 channels in the DSB 3 into fax data and transmits the data through the parallel bus.

Accordingly, the MPB 8 stores the fax data of the FPB 6 in the memory 9.

That is, the FPB 6 converts the 64 kbps of PCM data into 2400 to 1440 bps of fax data and stores it in the memory 9 through the MPB 8.

The IPB 7 converts the PCM data switched through the highway bus from the DSB 3 to the 32 channel channel into Internet phone data, and connects to the corresponding subscriber channel through an external Internet network (not shown). Make it possible.

That is, the IPB 6 converts the 64 kbps PCM data into 6.3 kbps, 5.3 kbps, or 8 kbps of Internet phone data, and then connects the Internet network to the corresponding subscriber channel through an external internet network (not shown) so that a call can be made. do.

The information stored in the memory 9 is reproduced by reversing the above process according to the signal inputted through the above process from the subscriber.

In addition, when the user accesses the Internet phone through an external Internet network, the above process is reversed and the subscriber accesses the corresponding subscriber channel so that the subscriber can make a call through the Internet network.

However, in the integrated service system according to the prior art, when the subscriber line capacity is determined, several types of cards are required to provide various services of voice, fax, or Internet phone. Accordingly, when providing multiple services, the subscriber line is divided into several lines. It must be divided and used, and the increase of the highway bus is required when the subscriber line is increased. In this case, it is difficult to expand the system.

For example, an integrated service system with 256 subscriber lines is divided into 100 lines of voice line, 100 lines of fax line and 56 lines of Internet phone when providing voice, fax or Internet phone service. If the 100-line Internet phone service providing request is connected at the same time there is a problem that the service 56 lines and service 44 is impossible.

Accordingly, the present invention has been made to solve the above problems, the internal circuit capacity increase method in the integrated service system to increase the internal rotation capacity by allocating an unused channel having a serial bus having a large capacity channel channel The purpose is to provide.
