VC-410 & VC410POE Ethernet Extender Manual
PIN1:
ON:
CO(Central Office) Mode or called Local Side, usually the CO device will be located at the
data enter of enterprise to link to the backbone.
OFF:
CPE(Customer Premises Equipment) Mode or called Remote Side, usually the
CPE side will be located at building, monitoring for car parks and train station as the
long reach data receiver.
Tip:
When the VC-410 & VC410POE operates at
CPE
mode, the DIP switch 2, 3, 4 has
no function
.
PIN2:
ON:
High Band mode(500KHz to 30MHz), and enable VDSL2 spectrum is 500kHz to 30MHz. It can
pass through
ISDN
spectrum(0 ~ 499KHz are empty).
OFF:
Low Band Mode(300KHz to 30MHz), the VC-410 & VC410POE will auto-detect the cable
length and auto choice speed mode.
PIN3:
When SNR margin is selected, the system provide
6db/9db
SNR margin for across all usable
loop length. Please note that the 6db SNR margin is for telecom standard. Generally speaking,
the higher SNR value gets better line quality, but lower performance.
PIN4:
ON:
Interleaved mode has a maximum end to end latency of
8m
sec and
INP=2
. When field
environment has heavy noise, in order to obtain high link quality, user can config pin4 to “ON”,
but this function will
reduce performance
.
OFF:
Interleaved mode provides impulse noise protection for any impulse noise with a duration
less than
1ms
.
