Description

Internet service matching device at the exchange

The present invention relates to internet service matching at a switchboard, and more particularly, to an Internet service matching device at a switchboard that provides an Internet service directly within a switchboard to a general modem subscriber connected to a telephone network.

In the conventional switching system, the packet service and internet service matching device includes a matching module 10, a high speed interconnection module 20, a packet network matching unit 30, and an internet network matching unit 40, as shown in FIG. ) Is made.

When the subscriber is connected through an external interface, the matching module 10 analyzes the subscriber information to determine the path of the required service and then applies it to the high speed interconnect module 20.

The high speed interconnection module 20 may be configured to convert the processed data applied from the matching module 10 into the packet network matching unit 30 for a general data service or the internet network matching unit 40 for an Internet service. Connect to.

The packet network matching unit 30 performs packet network matching.

The internet network matching unit 40 performs internet network matching.

Here, the matching module 10 includes a telephone network connection unit 11 for relay line matching function, R2 signal matching function, and network synchronization function for relay line matching through a digital relay line with a switch, and the connected subscriber to a modem subscriber processing unit ( 13) a telephone network connection processing unit 12 which receives a switching function and various alarms divided into 13) and informs an upper processor, a modem subscriber processing unit 13 which processes data of a subscriber connected via a modem, and generalizes the processed data. And a main processor 14 for determining a path to apply to the packet network matching unit 30 for data service or the internet network matching unit 40 for internet service.

On the other hand, the telephone network connection unit 11 is a relay line matching unit 11-1 for frame formation and monitoring of data applied from the relay line, insertion and detection of synchronization patterns, alarm and error detection, and seizure capture of trunk lines. R2 transmission and reception unit 11-3 for reporting the acquisition request information to the main control unit 14, receiving and translating the data channel applied from the trunk, and applying it to the telephone network connection processing unit 12 when receiving the received information. A network synchronizer 11-2 for dividing the main clock based on the clock received from the relay line matching unit 11-1 and dividing and supplying a clock required for each unit; and a first controller 11-4. Is done.

On the other hand, the telephone network connection processing unit 12 is a switching unit 12-1 for switching the subscriber data received from the relay line matching unit for each channel through the time switch to each modem subscriber processing unit 13, and the R2 transmitter and receiver ( And a second control unit 12-2 which collects data received from 11-3) and various alarm information received from the relay line matching unit 11-1 and reports it to the main processing unit 14.

As described above, when a subscriber is connected through an external interface in the conventional exchange, the telephone network connection unit 11 analyzes the link state and information on the subscriber and transmits the information to the telephone network connection processing unit 12, and the telephone network connection processing unit 12 In the present invention, each subscriber data is allocated to a timeslot and transmitted to the modem subscriber processing unit 13.

Accordingly, the modem subscriber processor 13 analyzes the subscriber information transmitted by the actual modem subscriber and applies the analyzed data to the main processor 14.

Accordingly, the main processor 14 determines the path to which the data is connected in order to receive the service requested by the subscriber and applies the high speed interconnect module 20.

In addition, the high speed interconnection module 20 connects according to the subscriber request signal authorized from the main processor 14 to receive the general data service or the Internet network service required by the subscriber. It connects to the network matching unit 40.

Then, the packet network matching unit 30 matches with the packet network, and the internet network matching unit 40 matches with the internet network.

As such, in the conventional exchange, in the packet network and the Internet network service, each matching unit is formed as one block in the exchange, and a large and overlapping function occurs and is connected through the trunk, so that maintenance and management cannot be performed in the exchange. You can only provide a path.

In addition, the functions used in the telephone network access unit that controls the R2 transmitter and receiver and the network network access unit that collects and processes the data authorized by the R2 transmitter and receiver and reports them to the main processor are redundant with those in the exchange. There is a problem that must be installed by connecting to the trunk and subscriber information is also managed separately.

The present invention has been made in view of the above-described problems, and includes an Internet service matching module in the exchange, so that the general subscriber connected to the telephone network can receive the Internet data service in the exchange without going through a separate external connection system. The purpose is to make it possible.

In order to achieve the above object, a feature of the present invention is that, in the Internet service matching device of the exchange, the subscriber matching and clock is received from the switch block of the exchange, and the subscriber matching to deliver the subscriber information of the subscriber at the time of subscriber access Wealth; A modem subscriber processing unit for analyzing and processing subscriber information transmitted from the subscriber matching unit; A data service system control unit for transmitting the analyzed subscriber information authorized from the modem subscriber processing unit for an internet network connection; An internet network matching unit for connecting an internet network to receive an internet service according to the subscriber information authorized from the data service system control unit.

On the other hand, the subscriber matching unit and the main control unit for performing a control operation based on the program: an external interface unit for interfacing the subscriber information transmitted and received between the main control unit and the upper processor; A sub-highway interface unit for interfacing the clock with general modem subscriber data applied from a switch block in the exchange; A clock supply and divider unit which receives a clock from the subhighway interface unit and supplies a required clock to the modem subscriber processor; A switch unit receiving general modem subscriber data from the subhighway interface unit and connecting general modem subscriber data to the modem subscriber processing unit under the control of the main controller; And an interface unit for interfacing subscriber control information transmitted and received between the main control unit and the data service system control unit.
