DIP-1: Mode (CO/CPE)
CO (Central Office) – the Master device mode, usually the CO
device will be located at the data center of ISP or enterprise
to link to the backbone.
CPE (Customer Premises Equipment) – the Slave device
mode, usually the CPE device will be located at branch office,
home or remote side as the long reach data receiver. The CPE
can be connecting to the PC, IP Camera or Wireless Access
Point or other network devices.
Note
When the Ethernet Over VDSL2 Converter oper-
ates at CPE mode, the DIP switch 2, 3, 4 is no
function.

DIP-2: Channel (Fast and Interleave mode)
Fast mode guarantees a minimum end-to-end latency less
than 1 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 10m sec.
n
DIP-3: Profile (17A/30A)
User has the ability to select profile. When 30a is selected
that provides better downstream/upstream performance in
short distance, when 17a is selected that provides longer
distance link capability. Refer to section 1.4 specification for
details.
n
DIP-4: SNR (9dB/6dB) Target SNR (Signal Noise Ratio)
Margin
When SNR margin is selected, the system provide 9dB/6dB
SNR margin for across all usable loop length.
