Questions
What is the procedure to aligning antennas?
How long should it take to test the E1 service and WS service
respectively by using the BER tester?
What alarms occur after the IF 1+1 switching is complete?
How can we ensure that SNCP switching is successful?
How should we handle bit errors occurring in the 24-hour BER test?
