Appendix A
We can preliminarily judge whether each interface is working properly by observing the light of each interface after device startup is completed.

Common Faults and Troubleshooting
This paragraph describes common mistakes and faults that may occur during installation and maintenance. Please seek support from company for other problems.

A.1 E1 Alarms
The E1 warning LED is set by Dip to confirm the local E1 alarms or remote E1 alarms, When E1 LOS LED is on, loss of E1 signal fault is detected. Troubleshooting is through the following steps:

• First: check the E1 terminal equipment, such as the PCM device, whether it is shutdown.
• Second: check if the E1 connection is reliable, whether the E1 cable is broken or loses, which will lead to the loss of input signal.

A.1 Cannot set up E1channel
Cannot set up E1channel may be caused by a variety of reasons, and the main causes as the following:

1. If both ends of the gateway are powered on.

2. If both ends of the device’s network cable are connected properly, observe that whether the link LED is on, the cable is good contact.

3. Check both ends of the network cable is normal.

4. Check the network that both ends of the device transport through is normal. By the ping command to ping NMS IP address of remote device(Need to confirm both ends of the NMS card IP address setting are right) or by using NMS send and receive data packets to check if the MAC address of peer equipment is obtain.

5. IP and MAC address settings of the device are normal (all 0s or all 1s is prohibited), check if the IP address in the network segment is repeated, the MAC address is unique.

6. Check whether the agreement of both sides is set to the same, as the following:

   • UDP/IPv4 corresponding UDP/IPv4
   • L2TPv3/IPv4 corresponding L2TPv3/IPv4
   • MEF corresponding MEF
   • MPLS corresponding MPLS

7. Whether both sides select the RTP header (both sides choose the RTP header, or both sides do not choose the RTP Header).

8. UDP mode, whether UDP port numbers that corresponding to the E1 port are the same; L2TPv3 mode, whether the session ID that corresponding to the E1 port are the same, the cookie can choose of both sides are consistent; the MEF mode, whether the ECID that corresponds to the E1 port is consistent; the MPLS mode, whether the inner label is consistent.

9. Whether both sides of the circuit simulation protocol settings is consistent.
   SAToP corresponding SAToP

   • TDM Pseudowire Access Gateway (not with CAS) corresponding TDM Pseudowire Access Gateway (not with CAS)
   • TDM Pseudowire Access Gateway (with CAS) corresponding TDM Pseudowire Access Gateway (with CAS)

10. Check that the transmission network has enough bandwidth. It can be judged by the growing number of NMS data buffer empty.

11. Check that whether the jitter from network is too large, to judge by the number of NMS data buffer empty and full. If the network jitter is too large, we can determine it is true or not by setting the jitter buffer size.

12. Check for E1 alarms, whether the local E1 cable dropped or poor contact or line broken. If there is a local LOS alarm, please check whether the end of E1 cable is dropped or poor contact or line broken.

13. Both ends of the gateway are set to the differential clock mode, but common clock source does not exist.

A.1 Downstream reporting slips
Check the timing mode settings of FE1 over GE. Whether both sides of the E1 in the asynchronous state. If there is no public reference clock source, FE1 over GE device timing mode must be set to adaptive timing mode, both ends cannot work in loopback timing mode. At the transition time after power on or reapplying the E1 signal, slips and errors are acceptable. Such transition may take several minutes.

If it slips for a long time, further analysis is required to find out the reasons. And it may be caused by one or several reasons:

1. The transmission network does not have enough bandwidth. It can be judged by the growing number of data buffer empty.
2. Network in half duplex mode, but the network needs to be in full-duplex status.
3. Network itself result in error.
4. E1 interface cable problems or poor contact.
5. E1 itself has line error.
6. Both sides of E1 equipment in asynchronous state, but both ends of the device work in loopback clock recovery mode.
7. Different sources clock of both ends of the device, but both ends of the device set to be at system clock operating mode.
8. One end of the device choose adaptive mode and the other end choose differential mode.
9. Both ends of the device set differential mode while their public reference clock from different sources.
10. make sure that both ends of the device have good ground.
