Introduction
- EthWAN provides the functionality to enable wan side connection through Ethernet port.
- The functionality is being used in deployments with ONU and Gateways.
- It can co-exist with DOCSIS, so that the WAN source can switch between EthWAN or DOCSIS
- If syndication partners want to deploy Comcast gateway and Wi-Fi solution for customers who have fiber connection, they will require this EthWAN feature.
- In other words this feature allows our syndication partners to offer service to their fiber customers.
Architecture
- Once enabled in device all internet data traffic including voice and device management will be done through Ethernet Port of the device.
- In Ethernet WAN mode device will connect to ONU* (at the customer premises) before it connects to Internet.
*ONU = Optical Network Unit.This is fiber MODEM equivalent of Cable MODEM (DOCSIS device)
