Standard extender
PD extender
SW-1: CO/Remote
Off: VDSL2 PoE Ethernet Extender will act as the master side.
On: VDSL2 PoE Ethernet Extender will act as the slave side.
SW-2: Mode for impulse noise protection
Off: Interleaved mode provides impulse noise protection for any impulse noise with a duration less than 250 µs.
Interleaved mode has a maximum end-to-end latency of 10 ms. Interleaved mode is the default mode.
On: Fast mode guarantees a minimum end-to-end latency less than 1 ms.
SW-3: Rate limit control
Off: Line rate limited to 50/20 Mbps.
On: Provides up to 100-/60-Mbps line rate at distances up to 500 feet (152.4 m).
SW-4: Signal-to-noise ratio (SNR)
Off: Higher SNR margin (9 dB) will result in fewer errors with a more stable VDSL link.
On: Original and normal channel noise protection with 6 dB SNR.
