WAN PHY is only useful if you need to run over SDH, so not useful over

The B1/B2/B3 parity counters are useful even over dark fibre as it'll
tell you if you're getting bit errors, even though that bit error didn't
hit any actual packet.
So it's useful for verifying link quality even before putting live
traffic on it.
That's an interesting idea. Are those counters well-exposed on kit that
supports WAN PHY?
