Two working modes are built in the same unit, which keep the
flexibility of installation and easy provision of service but lower
inventory of service provider.
Selectable fast and interleaved mode:
Fast mode guarantees a minimum end to end latency less than1
ms. Interleaved mode provides impulse noises protection for any
impulse noise with a duration less than 250 us, Interleaved mode
has a maximum end to end latency of 10 m sec. Interleaved mode
is the default mode.
Selectable target data rate and target SNR margin:
User has the ability to 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 up to 50 Mbps/30 Mbps whenever the calculated SNR margin
is higher than 9 dB. This gives best system stability and is the
default mode.
