2. The following table describes the DIP Switchs’ setting.
Pin 1 Pin 2 Pin 3 Pin 4
Side Channel Rate Limit SNR
Off CO Interleave Symmetric 9dB
On CPE Fast Asymmetric 6dB
Pin 1: CO, CPE switch
GO: LAN Extender acts as Central Office (CO) side.
GPE: LAN Extender acts as Customer Premise Equipment (CPE) side.
Pin 2: Impulse noise protection
Interleave mode: Provides communication protection for up to 250ms impulse noise
with latency less than 6 ms.
Fast mode: Direct data transmission with latency less than 1 ms.
Pin 3: Band Plan
Symmetric: Support the band plan G.997 and provide the symmetric transmission on
both down stream and upstream.
Asymmetric : Provides highest line rate in short range in asymmetric mode.
Pin 4: General protection
9dB: Better channel noise protection with SNR up to 9 dB
6dB: Original channel noise protection with 6 dB SNR.
