Below in conjunction with each accompanying drawing the embodiment to line method and alignment device thereof that the present invention is based on digital distribution frame is explained in detail.See also Fig. 7, this figure is the main implementation procedure principle flow chart to line method that the present invention is based on digital distribution frame; Its main implementation procedure is as follows:
Step S10 generates detection signal; Wherein the detection signal of Sheng Chenging can be pseudo noise code (prbs), because pseudo noise code (prbs) is the repeatably binary sequence with random signal statistical property, load PDH (Pseudo-synchronous Digital Hierarchy) (PDH so use pseudo noise code,) or SDH (Synchronous Digital Hierarchy) (SDH,) transferring data frames, whether the connection cable that not only can test as transceiver channel between network element device and the DDF connects correctly the problems such as quality of connection that can also test connection cable; Certainly the detection signal that generates also can be the test patterns of other types; Wherein generate detection signal mode can for:
Generate detection signal by the network element device in the network system self; Or
Being provided with one can support the detecting instrument and the network element device in the network system that generate detection signal to carry out intercommunication.
Step S20 sends to DDF with the detection signal that generates by the connection cable as sendaisle between this network element device and the digital distribution frame DDF by the network element device in the network system;
Step S30, described network element device judge whether and can receive this detection signal by the corresponding connection cable as receive path between this network element device and the DDF, if, execution in step S40; Otherwise execution in step S50;
Step S40 shows that this connection cable connection to the transceiver channel correspondence is correct between network element device and DDF;
Step S50 shows that there is fault in this connection cable connection to the transceiver channel correspondence between network element device and DDF.
Network element device in the wherein said network system can be optical transmission device, also can be for comprising other network equipments that wait a large amount of cables of needs to connect of stored-program control exchange.And at present in network system, most of E1/T1 mapping (Mapping) modules that optical transmission device uses are all supported functions such as puppet generation of sign indicating number test patterns such as (prbs) immediately and monitoring, utilize this function of E1/T1 mapping block to generate test signal like this, whether correctly connect with the connection cable between light travels equipment and the DDF, this implementation does not only need instrument in to line process, but also can find cable connection error and cable open circuit, short circuits etc. are serious to connect fault, and can find because impedance does not match, the distorted signals fault that plug loose contact etc. causes.As: the optical transmission device in the network system can be encapsulated in the pseudo noise code (prbs) that generates in the E1 signal and send to DDF by the sendaisle between optical transmission device and the DDF.
Wherein being used to receive the output port Tx of the detection signal that network element device sends on the DDF and being used for this detection signal of loopback is the transmitting-receiving port of going the same way for the receiving port Rx of described network element device, as shown in Figure 8, this figure be the present invention is based on digital distribution frame to the enforcement schematic diagram of line method under DDF goes the same way transmitting-receiving port direct-connected situation, as shown in Figure 8, DDF goes the same way and receives and dispatches the direct-connected situation of receiving port Rx that port is meant last each output port Tx of DDF and correspondence, and is so specifically as follows to line process:
1) sets gradually that each sendaisle is pseudo noise code (prbs) sendaisle in the network element device (being that example describes with the optical transmission device) in the network system here, be that connection cable between optical transmission device and the DDF can be used for transmitting the prbs sign indicating number, wherein this function can realize by the relevant control register of the E1/T1 mapping block in the read-write optical transmission device;
2) the prbs sign indicating number sending function of each sendaisle in the startup optical transmission device;
3) optical transmission device scans all receive paths successively, judge whether to receive that correct prbs pseudo-random code stream is not (because DDF can carry out any processing to signal, can only carry out loop back processing being to signal, so should be consistent by the prbs pseudo-random code stream that sendaisle sends to DDF) with optical transmission device by the prbs pseudo-random code stream of DDF loopback;
4) if optical transmission device does not correctly receive the prbs code stream by receive path, perhaps received correct prbs code stream, but find to send the sendaisle number of this prbs code stream and receive the receive path of this prbs code stream number inconsistent, then optical transmission device thinks that there is failure problems in this connection cable to the transceiver channel correspondence, reports corresponding error information.
Wherein above-mentioned shown in Figure 8 to line process can detect except that to line transmitting-receiving connect anti-, to all the connection error faults the dislocation between line and impedance fault such as do not match.
In addition, be used to receive the output port Tx of the detection signal that network element device sends on the DDF and be used for this detection signal of loopback that to give the receiving port Rx of described network element device also can be dislocation transmitting-receiving port, as shown in Figure 9, this figure be the present invention is based on digital distribution frame to the enforcement schematic diagram of line method under the situation that DDF dislocation transmitting-receiving port connects, as shown in Figure 9, DDF dislocation transmitting-receiving port is meant that dislocation is connected with receiving port Rx with the external output port Tx of DDF with cable, and Tx1 connects Rx2, Tx2 and connects Rx3......TxN-1 connection RxN as shown in Figure 9; Certainly opposite the connection, connect TxN as Rx1 connection Tx2, Rx2 connection Tx3......RxN-1 and also can.Under the situation that dislocation is connected with receiving port Rx of each output port Tx on the DDF, concrete is as follows to line process like this:
1) sets gradually that each sendaisle is pseudo noise code (prbs) sendaisle in the network element device (being that example describes with the optical transmission device) in the network system here, be that connection cable between optical transmission device and the DDF can be used for transmitting the prbs sign indicating number, wherein this function can realize by the relevant control register of the E1/T1 mapping block in the read-write optical transmission device;
2) the prbs sign indicating number sending function of each sendaisle in the startup optical transmission device;
3) optical transmission device scans all receive paths successively, judges whether to receive correct prbs pseudo-random code stream;
4) if optical transmission device does not correctly receive the prbs code stream by receive path, perhaps received correct prbs code stream, but the receive path that find to send the sendaisle number of this prbs code stream and receive this prbs code stream number does not meet transmitting-receiving port dislocation annexation shown in Figure 9, then optical transmission device thinks that there is failure problems in this connection cable to the transceiver channel correspondence, reports corresponding error information.
Wherein above-mentioned shown in Figure 9 to line process and above-mentioned shown in Figure 8 similar to line process, just changed the wiring relation of DDF outside port, and do not connect between the 1st transmit port and the last receiving port, thus shown in Figure 9 to line process also can detect except that to line transmitting-receiving connect anti-, to all the connection error faults the dislocation between line and impedance fault such as do not match.
In conjunction with above-mentioned shown in Figure 8 to line process and shown in Figure 9 to line process, can also there be the third implementing measure to exist, see also Figure 10, this figure the present invention is based on digital distribution frame line method is directly connected and misplace enforcement schematic diagram under the situation about being connected of DDF transmitting-receiving port at the transmitting-receiving port of going the same way in conjunction with DDF; Describedly be meant with cable than length in conjunction with the DDF situation that the transmitting-receiving port directly connects and the dislocation of DDF transmitting-receiving port is connected of going the same way, the output port TX1 of the fixedly connected DDF of one end, the other end connects receiving port Rx1, Rx2......RxN in order successively, specifically as shown in figure 10.Concrete like this is as follows to line process:
1) setting initial time-out time is 30 minutes, connects hand-off process by manually finishing cable shown in Figure 10 then; The sendaisle that the Tx1 correspondence at first is set is a prbs code stream sendaisle; What current expectation was set respectively is receive path 1, receive path 2...... receive path N with the corresponding respectively receive path of receiving port Rx1, Rx2......RxN, and the receive path that each expectation is set is a prbs code stream receive path;
2) when the receive path that detects certain expectation from can not correctly receiving the prbs code stream to can correctly receiving the prbs code stream, can not correctly receive the prbs code stream again then, show that then the connection cable of this receive path correspondence has been switched on once; Write down this receive path that is switched on number, and time-out time is set is 10 seconds;
3) relatively whether the receive path number of expectation and the actual receive path that will detect be number identical, different then show that there is failure problems in the receive path of this expectation, need report corresponding bug information; The receive path of expectation number adds the detection that next receive path is continued in 1 back.
Wherein shown in Figure 10 can detect the failure problems that the connection cable as all receive paths between network element device and the DDF exists to line process, as comprise and connect anti-and to fault such as misplacing between line, but whether normally but can not detect as the connection cable of sendaisle between network element device and the DDF to line transmitting-receiving.
To sum up, if shown in Figure 8, can detect existing all faults of connection cable between network element device and the DDF to line process and shown in Figure 9 line process is used.If simultaneously shown in Figure 8, also can detect existing all faults of connection cable between network element device and the DDF to line process and shown in Figure 10 line process is used.
