Closed-circuit television monitoring system, video installation set what quotasfixed
Install the transmitter should apply the PDH quota, because the transmitter is E1 signals converge into optical signals equipment, first apply the machine frame, then apply the TSY2-001 quota, quota TSY2-002/TSY2-003 interface disk, finally use the test system channel test quota TSY2-046--TSY2-050.
In a digital communication system, the transmitted signals are digitized pulse sequences. When these digital signal streams are transmitted between digital switching devices, the rate must be completely consistent so as to ensure the accuracy of the information transmission. This is called synchronization".
