Q1. How to select CO side and CPE side mode PMC?
A1. Referring to the figure below, the PMC B module (nearest to IP camera) is the CO side and
PMC A module (nearest to control center) is the CPE side for valid operation bandwidth.
RJ45
Q2. How to identify fast and interleaved mode?
A2. Fast mode guarantees a minimum end to end latency of less than 1 ms. Interleaved mode
provides protection from any impulse noise with duration of less than 250 μs. Interleaved mode
has a maximum end to end latency of 10 ms. Interleaved mode is the default mode.
Q3. How to select target data rate and target SNR margin?
A3. User can select fixed SNR margin (9 dB) or fixed target data rate. When fixed SNR margin
is selected, the systems will maintain the SNR margin at 9 dB across all usable loop length.
When fixed target data rate is selected, the system will lock the data rate at 50Mbps/30Mbps
whenever the calculated SNR margin is higher than 9 dB. This provides the best system
stability and is the default mode.
Q4. Why PMC modules cannot link each other after training?
A4. 1) A pair of PMC modules should consist of a CO side mode module and a CPE
side mode module. They cannot be of the same mode modules.
2) RJ-11 jack and connector may have loose contact.
3) The distance between 2 PMC modules should not exceed 1.5Km.
