What version/build of firmware?
What steps did you take to configure it?
Have you confirmed the connection works with a different device?

You may need to debug what's going on.
Use the instructions below from expert CLI.

Packet capture:
• To capture PPPoE headers [[PADI,PADO,…]:
tcpdump pppoed -i any
• For control packets:
tcpdump pppoes -i any

Debug:
sw dbg l 4,connmgr
sw dbg ppp
sw dbg 2 dsl
sw dbg tty /storage/debugdsl.log

To turn off the debug:
sw dbg l 0
