It's probably a binary format where you'll need to know the byte off-sets for each field.  I haven't done it for this format, but we looked at doing it internally for another C15 (Nortel/Genband/Ribbon) file and decided against it.  Turns out they had a free (if you have full support) program that would decode them.  I've seen the AT&T Cabs files and never found an easy way to decode them.  They used to ship us a CD with the files, but someone lost the program CD to use to decode it.

And yes, I know it doesn't contain the file format - but sometimes
just having the correct definitions helps. I do think the file
format's published _somewhere_ ... but digging it out is another
matter.
