If we encounter line unreasonable conditions during the installation of equipment, along with various types of warnings on the equipment, how should we solve it? The following describes the protocol converter problems and solutions
First, V.35 protocol converter common indicator meaning 1, LOS: alarm indicator, LOS is the converter E1 signal loss indicator signal, normal light off;
2. AIS: Alarm indicator, AIS is the converter E1 input to the transmission device cable connection is normal, but no signal. In this case, the converter only receives the full "1" code sent by the transmission device, and this LED is off when it is normal.
3rd, TD: The data sends out the indicating lamp, TX is the converter V.35 data transmission indicating signal, this lamp lights normally;
4, RD: data received light, RX is the converter V.35 data receiving indicator, normal light.
Second, troubleshooting, analysis and resolution
1. Fault: The V.35 line is disconnected and the LOS alarm indicator of the converter is on.
Analysis: The LOS alarm appears on the converter, indicating that the loss of the E1 signal from the transmission equipment to the converter has occurred.
Cause and Solution: a. The E1 cable connected to the optical transceiver E1 and received by the converter E1 has failed. You can use a multimeter to measure judgments. Replace the E1 cable to resolve the fault.
b. The optical transceiver is faulty, no signal is transmitted on the E1 interface, or the optical transceiver is not powered. The multimeter can be used to measure whether the optical transceiver has a power input, or whether the optical transceiver power is short-circuited, or observe the LOS alarm status of the optical transceiver E1 interface. Repair the power supply system or replace the optical transceiver to solve the problem.
c. converter failure, E1 interface can not receive signals. You can judge the LOS alarm status by disconnecting the converter's Ethernet cable and looping through the E1 interface. The LOS alarm is not cleared, and the device fault is determined. Replace the converter to solve the problem.
2. Fault: The V.35 circuit is inaccessible and the AIS alarm indicator of the converter is on.
Analysis: The AIS alarm appears on the converter, indicating that the connection between the optical transceiver E1 and the E1 cable received by the converter E1 is normal, but there is no signal. At this moment, the converter receives all "1" codes sent by the local optical transceiver.
Causes and analysis: a. The peer optical transceiver did not receive the E1 signal sent by the disconnect converter. Check whether the peer E1 cable connection is normal.
b. The peer optical transceiver and the converter cannot be powered up. The power supply system must be inspected and repaired.
c. The peer optical transceiver and converter are damaged. Check the device and replace the device.
3, failure: V.35 line is not open, RD light does not shine.
Analysis: The RD light of the converter does not light, indicating that the converter has not received the signal sent by the router.
Cause and Analysis: a. The router V.35 module is damaged and cannot send V.35 signals. Need to replace the router to restore the line.
The bV35 cable is faulty and cannot transmit V.35 signals. Replace the converter or router V.35 cable recovery line.
c. converter failure, can not receive V.35 signal. Replace the converter to restore the circuit.
4, fault: V.35 line is not open, TD lights do not shine.
Analysis: The peer V.35 signal is not transmitted to the local end and no signal is sent from the local end to the local end router. The non-lighting of this end is not related to the local end-to-end converter and router, and the non-local end equipment is faulty.
Causes and analysis: a. The peer router is not able to send V35 signal when the peer router is damaged, or the converter is damaged and cannot receive the V.35 signal, or the V.35 cable is faulty. The RD indicator will not be turned on at the peer end converter. Replace the router recovery cable. .
b. The peer routers and converters cannot add points. As a result, the V.35 signal cannot be transmitted to the local end, and the local end and no signal are output.
Third, the conclusion
When the V.35 line fails, it is necessary to check whether the power of the remote device is normal. Then, check whether the E1 transmission line is normal. Then, check whether the fault occurs in the central office or the remote site through the indicator of the converter. Finally, pass the test. Set up and replace equipment to solve the problem. In addition, in the Ethernet transmission network, network loopback (such as E1 loopback and Ethernet loopback) cannot occur. Otherwise, network storm may occur, resulting in Ethernet data collision or network corruption.
