Hello Frank,

(beware non-technical readers - very technical comments)

Stepping in, potentially over my head, I did some looking around. It appears that there is a standard (RFC1619 - info.internet.isi.edu:80/in-notes/rfc/files/rfc1619.txt ) which defines the use of PPP over SONET. Obviously PPP provides a way to transport IP ...

Also, upon looking through some other documentation, it appears that there are some theoretical problems that have been discovered in this mapping. There are several Internet Drafts dating from October and November of 1997 discussing a way to correct this:

search.ietf.org:80/search/cgi-bin/BrokerQuery.pl.cgi?broker=internet-drafts&query=SONET&caseflag=on&wordflag=off&errorflag=0&maxlineflag=50&maxresultflag=1000&descflag=on&sort=by-NML&verbose=on&maxobjflag=25

... including several involving Sprint, working to resolve these potential problems. One of the drafts indicates that this RFC has been implemented and is in use today, and has been, with minimal issues.

I'm no SONET expert, and need to do some reading to figure out exactly what SONET/SDH is ... but it appears that these standards might be the ones being used by Sprint today.
