Well, assuming that it is ISO 8073, there is an RFC (rfc905 from 1984!) and it relates to the original OSI specification for connection-oriented services (making it a cousin of TCP):

 

Beyond that, the RFC is long and not terribly well organized (it is lifted directly from the ISO specification, apparently), so for better-or-worse, you'll have to try and sort through it. You might consider engaging F5 Professional Services, a for-pay consulting arm of F5. They should be able to take the time to work through protocol details with you and craft an appropriate iRule based on the specification.
