It is worth mentioning that, in the utility model execution mode, no matter be the first communication port, second communication port, third communication port and the 4th communication port in dialing control appliance or network traffics treatment facility, be all for distinguishing different ports, and be not used in the quantity that limits port.That is to say, the first communication port that above-mentioned execution mode is mentioned, second communication port, third communication port and the 4th communication port are likely all one or more ports.

Also have, the data to be sent in the unlike signal source of mentioning in the utility model execution mode, just for representing the data of unlike signal, but the data to be sent that are not a signal source of restriction can only be from a physical equipment, likely the data to be sent in a plurality of unlike signals source, also may be respectively from different physical equipments all from same physical equipment.

On the basis of the above-mentioned dialing control appliance providing and network traffics treatment facility, the utility model further provides a kind of communication system, and the communication system of present embodiment comprises dialing control appliance and the network traffics treatment facility of above-mentioned execution mode.In communication system, between dialing control appliance and network traffics treatment facility, realize communication, specific implementation process refers to the associated description of Fig. 1 illustrated embodiment.Wherein, the function of inner each assembly of dialing control appliance and network traffics treatment facility realizes the associated description that refers to Fig. 2-Fig. 3 illustrated embodiment, at this, is not repeating.

Refer to Fig. 4, Fig. 4 is the flow chart that utilizes the execution mode of method that communication system of the present utility model communicates, and present embodiment is to describe with the angle of above-mentioned dialing control appliance, and the communication means of present embodiment comprises:

Step S101: dialing control appliance receives the data to be sent from least two unlike signal sources;

When having data to send, network traffics treatment facility will send to dialing control appliance after the packet to be sent from unlike signal source.In the utility model execution mode, data to be sent can be from two or more signal sources, below for elaborating the technical solution of the utility model, with the internet data signal from the Internet with from the IP transport of internet digital television signal data instance of IP transport of internet Digital Television private network, describe, for other the transfer of data in a plurality of unlike signals source, also can be applicable equally.

Dialing control appliance receives internet signal data and the IP transport of internet digital television signal data after grouping that transmit by time-sharing multiplex from network traffics treatment facility.

Step S102: dialing control appliance dials accordingly with the signal source under data to be sent respectively, and corresponding unlike signal source is set up for transmitting at least two transmission channels of data to be sent;

Dialing control appliance, according to the signal source under data to be sent, dials, and at least two transmission channels between dialing control appliance and the destination address place equipment of data to be sent are set up in corresponding unlike signal source.That is to say, data to be sent belong to several signal sources, with regard to corresponding dialing, set up several transmission channels.

Such as, what dialing control appliance received is internet signal data and IP transport of internet digital television signal data, carries out the Internet public network dialing and the dialing of IP transport of internet Digital Television private network, sets up public network transmission channel and private network transmission channel simultaneously.

Step S201: network traffics treatment facility obtains the data corresponding to be sent at least two unlike signal sources;

Network traffics treatment facility carries out physics addressing, error checking, frame sequence and Flow Control to all data to be sent.

Network traffics treatment facility from third party device such as Intelligent set top box, PC etc. obtains all data to be sent.

Such as network traffics treatment facility is by direct connection Intelligent set top box or connect respectively computer and common machine top box obtains internet signal data and IP transport of internet digital television signal data.

Step S202: by the packet corresponding to be sent at least two unlike signal sources, form corresponding data message and be packaged into packet;

After network traffics treatment facility gets data to be sent, according to the source address of these data, destination address and IP option etc., data are divided into groups, form data message and be packaged into packet.To the sequence of packet process and Flow Control.

Such as by internet signal data and the packet of IP transport of internet digital television signal, form data message and be also packaged into internet signal packet and IP transport of internet digital television signal packet, by these data packet sequencings and Flow Control by internet signal data and IP transport of internet digital television signal Data dissemination to the control appliance that dials.

Step S203: data packet sequencing is distributed to dialing control appliance by time-sharing multiplexing technology, so that dialing control appliance dials accordingly according to the signal source under data in packet, corresponding unlike signal source is set up for transmitting at least two transmission channels of data to be sent;

Particularly, network traffics treatment facility adopts statistics time division circuit to carry out multiplexing, non-difference link, parallel running, can not only greatly improve channel utilization index, further can set up a plurality of nodes by network traffics treatment facility simultaneously, be based upon the communication capacity between source node and destination node.
