There has been a recent bit of scare mongering from Lucent about PPP over SONet/SDH over on the IETF-PPP list. Has anyone (that has deployed) been having incident reports? For anyone seriously interested in the deep technical issues, you might send "subscribe pppsdh" to pppsdh-request@greendragon.com. I hope to cover operational issues in the next revision of RFC-1619, so I'd really welcome folks already deploying this on the Cisco or Ascend.
