ALL-MC115VDSL2 Mini Modem Master/Slave Manual
16
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 ALL-MC115VDLS2 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(25KHz to 30MHz), the ALL-MC115VDLS2 will auto-detect the cable length and auto choice speed mode.
VDSL2 spectrum is 25KHz to 30MHz.
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
.
