Hey all,

Does anyone have a reference for the differences between the various US PRI protocols (Nat'l 1, Nat'l 2, 5E, DMS, etc)? I'm specifically interested in features available via signalling. I've read that National ISDN, for the most part, has a smaller subset of features than any other protocol, but I can't find a chart or good reference that details them all.

The * page says it supports all the major protocols here in the US, but libpri only seems to have National support (from what I can see in the code). Can anyone confirm this?

Thanks,

Brad Waite
