Relationship toStandards Bodies OIF seeks to leverage and complement the work
of standards bodies• IETF, ATM Forum for data networking standards• T1 (US) and ITU for SONET/SDH and the
Optical Transport Network, OTN

OIF Initial ScopeApproved January 1999
The OIF’s first implementation agreement will specify a set of protocols for packet/cell based communications over optical channels utilizing SONET/SDH* framing and other protocols to be determined.
*This does not preclude the use of other protocols in the future
