III. Specifications on Equipment Principle

2048Kb/s (E1) data signal is conveyed to multi-service transmission equipment, which type of code is HDB3 code. After unipolar and bipolar change, HDB3 code becomes bipolar code. Then special integrated chip pick up clock, decode the signal code through adjustment of code and multiplex to code of driving optical signal. 10/100Base-Tx Ethernet data signal is converted into MII port data and transmitted to the special integrated chip. The data is copied to code of driving optical signal, and then sent out by the driving circuit.

 

Received optical signals enter into optical receiver, and are transmitted into the special integrated chip, through NRZ signal and clock signal generated by balanced amplification and circuit, to draw clock and decode. Through code rate resetting circuit and lock phase loop with inner figure restore and become 2.048Mb/s (EI) signal and MII Ethernet signal. Then the HDB3 Signal and 10/100Base-Tx Ethernet signals are sent out by the output driving circuit.

VIII. Protection and Replacement Norm for Dual Optical Path

PDH optical transmission equipment with dual port can realize 1+1 service protection. Protection for operation mechanism is divided into two parts –replacement and reset. The former one is that working channel is switched to spare channel when working channel happens to malfunction; The latter one is that spare channel is switched to original working channel because of replacement and solution to malfunction of original working channel.

8.1 Replacement Mechanism 

Taking the mechanism of dual send and sound receive is that send port will be sent simultaneously in the same service in two optical fiber; Main channel based upon fixed (ex-factory---default is 0.) when send port is normal. When main channel happens to malfunction and spare channel is normal, the main channel within 50ms can switch to spare channel to receive data and give out warning for network management.

 

Malfunction of Optical Channel Include:

·       Optical signal disappear.

·       Frame with malfunction loss.

·       Channel error code surpass the limitation.

8.2 Reset Mechanism 

Network management can configure can decide whether or not to reset and reset wait time after reset. Main channel may be on-and-off phenomenon in the course of malfunction rewetted. In order to avoid frequent replacement, continue previous operations after the channel keeps stable. Please refer to SDH technological standard. Resetting wait time is 5-12 minuets in usual condition.

8.3 Network Management Function 

·       Network management may decide working channel and protection channel; 

·       Network management may compulsorily switch to certain channel;

·       Network management may set after replacement whether or not to reset wait time;

 

IX. Test for Maintenance

MST155B/C series optical modem support test for maintenance by network management or dipswitch with loopback, BERT and so on.

·       Controlling Way of Maintaining Test

Ø                      Equipment with ex-factory is under the condition of default. Under the condition, switch of dip switch is available.

Ø                      The equipment is characterized by the choice of between "maintain operation controlled by switch of dip switch ”or "maintain operation controlled by network management” and it possesses the function of protection when cut down electricity.

Ø                      "Maintaining operation controlled by network management” must be setted in advanced to make test for maintenance through network management.

Ø                      To operate the clear out cut-off electricity is through maintenance to network setting.

·       BERT Test Principle

The inner of equipment is laid simple error code instrument that may through dip switch or inner error code instrument to reach data channel of receive and send. Panel indicator light may direct the synchronous condition , the class of error code (non-error code , <、>). And network management may memory time of coming out error code and the number of error code. BERT need loopback of E1 interface, local E1 in series and other assisted way, etc.

 

 

X. Data Exchange Channel of E1/V.35

·       (D)PDH120Vn+100M、(D)PDH120Vn+400M support data channel optional exchange of E1/V.35 so that V.35 channel is easily corresponding to E1channel of remote equipment. (Our company ‘s other 4E1, 8E1 optical transfer equipment);

XI. Solution to Common Malfunction

11.1 Optical Lost Warning: optical synchronization loss indicator light (SYLOS, RED) is on 

·       check connection optical fiber with optical modem, whether or not, is perfect;

·       Whether or not optical fiber with receives and send is connected each other in the opposite direction;

·       To check optical interface of equipment, whether or not , is well-function;

·       To check whether or not optical link is good to test optical receive power.

11.2 E1 Warning

Each E1 has two indicator lights , namely, AIS(yellow) and WORK(green). WORK light is a kind of working indicator which will be on when working in normal conditions; AIS light is a warning light for receiving full "1”code.

·       When WORK light is off, relative staff should check joining line of E1 remote interface to connect availably or not, examine quality and extension of joining line and test operation of all users is well-function or not;

·       When WORK light is on , check the working condition for equipments of all users.

11.3 Remote Interface Warning 

Local interface RA light is on, which indicates the remote interface optical receive signal or synchronization loss with the remote interface. Relative staff should check send optical signal with local interface and receive optical signal with remote interface and optical link.

11.4 The High Rate of Error Code

To check interface impedance is set rightly or not. If interface impedance is right, relative staff examine segment by segment through error code instrument, taking removing way to check the cause of malfunction coming from local optical path or the equipment itself
