Figure 2.2 DIP Swtiches

Pin 1: OT, RT switch
– OT: LAN Extender acts as Central Office (CO) side.
– RT: LAN Extender acts as Customer Premise Equipment (CPE) side.

Pin 2: Impulse noise protection
– 30a: High Speed Mode. Provides communication protection for up to 250ms
impulse noise with latency less than 6 ms.
– 17a: Long Reach 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 trans-
mission on both downstream 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
