PPPoE is a network protocol commonly used to allow DSL subscribers to "dial-in" to their DSL subscriber line. This is a common protocol which is used by telephone companies providing DSL services.
Cloud-Links and PPPoE
Cloud-Link/OmniShield does NOT support PPPoE directly as it is not itself a modem. However, an OmniNet Classic can simply be connected downstream from the modem performing the PPPoE role and connecting a site to their DSL subscription.

Additional note for sites relying on DSL service: DSL subscriptions over ATM networks have a maximum MTU of 1500. Network Protocols, including ethernet, take up some of those maximum 1500 bytes. It would be highly recommended for any partner deploying to an site relying on DSL service to understand what a locations maximum MTU size is and adjust their modem to the right size before deploying a Cloud-Link. OmniNet recommends a size of 1452 as per our article at the link below.
BYOG and PPPoE
Please refer to the documentation provided by your hardware vendor of choice. This is hardware specific but many gateways do support the ability to perform PPPoE function to connect a location to their DSL subscription. Your ISP may also have a listed of support hardware.
