The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). ITU-T Recommendation E.751 was revised by ITU-T Study Group 2 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 19th of February 1996. ___________________ NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. © ITU 1996 All rights reserved.

The primary purpose of the reference connection is to provide a basis for developing traffic Grade of Service (GOS) Recommendations for networks supporting mobile services. The underlying FPLMTS call flow model in the reference connection should be used as a basis for more implementation-specific configurations for detailed performance analysis and GOS target setting. ii Recommendation E.751 (02/96) Recommendation E.751 Recommendation E.751 (02/96) REFERENCE CONNECTIONS FOR TRAFFIC ENGINEERING OF LA
