To check the connectivity of the network cable, you can also adopt the approach of looping back the
data ports (applicable to the data ports on two sets of equipment that is powered on). That is,
connect the two data ports with the network cable. If the LINK indicator is on, it indicates that the
network cable is normal.

2. The software commissioning engineer searches for and creates NEs to ensure that the device
can be managed remotely. Then, the software commissioning engineer configures data for the
site to ensure that the device is functioning properly and alarm and performance data can be
reported.
1. An hardware installation engineer powers on the device, sets up optical paths, and informs
a software commissioning engineer in the network management (NM) center that the device
is powered on and optical paths are set up.

3. The software commissioning engineer sets outloops for E1 ports on the NMS, and instructs
the hardware installation engineer to test the bit error rate (BER) using a BER tester.
• If no bit errors occur or loss of signal (LOS) signals are displayed, the E1 cables are normal.
• If bit errors occur or LOS signals are displayed, check whether the 2 Mbit/s cables are
incorrectly connected or poor soldering occurs.
