According to "John" on his posting at learningnetwork.cisco.com, the first known reference to the so-called Gang of Four term in frame relay and LMI discussions can be traced back when four consortium composed of Cisco Systems, Inc., Digital Equipment Corp, Northern Telecom, and StrataCom, Inc., developed and published the the LMI for UNI.

"The LMI is a set of enhancements to the basic Frame Relay specification that include the following:
Virtual circuit status messages— The only common extension
Multicasting messages— Optional LMI extension
Global addressing messages— Optional LMI extension
Simple flow control— Optional LMI extension
The derivatives of the LMI Consortium were formally adopted as T1.617 Annex D and Q.933 Annex A. The first group of messages, known as the virtual circuit status messages, are the only common LMI (adopted by all vendors) extensions."
