ITU-T X.124
Arrangements for the interworking of the E.164 and X.121 numbering plans for frame relay and ATM networksMore info
This Recommendation defines the procedures applicable for the purpose of numbering plan interworking between ATM Networks which use the E.164 numbering plan and Public Frame Relay Data Networks which may use either the X.121 numbering plan or the E.164 numbering plan. The principles for interworking between the E.164 and X.121 numbering plans covered in this Recommendation are illustrated by various examples. The scenario (for FR/ATM service interworking) where the ATM terminal is identified by an AESA (NSAP) is also illustrated.
