Description
Technical field
The present invention relates to TV domain, especially a kind of reverse link test method based on C-DOCSIS networking structures and
System.
Background technology
With the arrival of wave of digitalization, conventional cable television industry is subject to unprecedented impact, mutual shadow in industry
Sound, infiltration, the integration of three networks are imperative, and full-service operation is the unique channel that broadcasting and TV develop under new environment；And C-DOCSIS
The network that networking model is built will lead the innovation of whole radio, TV and film industries under high bandwidth, the advantage of low cost.
For the QOS of Logistics networks transmission, user satisfaction is improved, the hfc plant based on C-DOCSIS will become broadcasting and TV
The following main network model of net.And greatest problem existing for the hfc plant transmitted in both directions based on C-DOCSIS is up channel
Noise collection effect problem.Since hfc plant using hub-and-spoke configuration, the return noise of multiple users can converge to C-CMTS
Same port, so as to form " funneling effect " of noise, causes the bottom of signal to make an uproar height, signal-to-noise ratio declines, and have impact on transmission matter
Amount.Since noise source comes from user terminal, it is not easy to be controlled supervision, it is therefore desirable to increase reverse strand path test system, to HFC
The reverse signal of network is monitored, so as to carry out troubleshooting to reverse radio-frequency link failure.
As shown in Figure 1, conventional counter link test method comprises the following steps：
（1）, one 9581sst equipment is installed in secondary front end, under setting downlink to send frequency point and then send
Row broadcast singal transmits inside hfc plant.
（2）Import tester is held（Such as 860dsp handheld terminals）In the propagation that user terminal reception 9581sst equipment is sent
Signal, then retransmits radiofrequency signal and back transmits.
（3）The 9581sst equipment in computer room is divided holding import tester and sending the radiofrequency signal come up and sample
Analysis, is then sent to hand-held import tester by the inverse frequency spectrum situation analyzed and is observed in real time.
Wherein, it is all by secondary front end to field luminous point to hold import tester and 9581sst communication between devices
Two core fibres carry out.Single optical fibre transmission has modulated 9581sst downlink signals, the DVB TVs letter in different frequency
Number and CMTS downlink data signals.And reversely return path signal is then transmitted by other core optical cable, optical cable transmission modulation
In the passback radiofrequency signal that the user data signal of different frequency and hand-held import tester are sent.
Traditional networking structure carries out an interaction for receiving a hair by secondary front end equipment and outdoor hand-held terminal device
To reflect the situation of whole link in real time, so as to facilitate operation maintenance personnel to fix a breakdown at the first time, noise source is found out.
As shown in Fig. 2, different from traditional networking structure, C-DOCSIS networking structures will be originally in secondary front end
CMTS withdraw from the two-way ray machine for being displaced downwardly to field, and new clothes are set with the field C-CMTS OLT to communicate in computer room
It is standby.Since C-CMTS installations are put in the wild, it needs the bidirectional data transfers that single-core fiber is carried out using a core of original optical fiber
（Carried out by pon technologies）；And in addition single optical fibre then needs the DVB TV signals that transmission is broadcast out from computer room, therefore divide
The transmission path of headend room to outdoor luminous point has been occupied full.In the case where not increasing number of fibers again, original hand
Hold import tester and the radiofrequency signal that no path is sent to is returned to 9581sst equipment in secondary front end.Therefore,
Existing C-DOCSIS networking structures need additionally to increase an optical fiber when carrying out reverse radio-frequency link test, this undoubtedly increases
The totle drilling cost of test, and it is not convenient enough.In addition, existing C-DOCSIS networking structures are carrying out reverse radio-frequency link test
When also need to be equipped with dedicated hand-held import tester, which involves great expense, and further increases test
Totle drilling cost.
