National Numbering Conventions
The National Numbering Conventions (abbreviated to the ¡¥Conventions¡¦) is the set of ¡¥rules¡¦ under which the Irish National Numbering Scheme will in future be managed and administered.
National Numbering Scheme
The national numbering scheme specifies the status of numbers or number ranges within the public telecommunications network in Ireland which may be dialled from that network or externally, and is as published by the Director from time to time.
Network Unique Short Code (NUSC)
A NUSC is one of a strictly limited number of short codes dedicated to offering services which are restricted to use within the network concerned. The NUSCs are therefore never normally transmitted across network to network interfaces. The use of each code must be notified to and agreed beforehand between the network operator concerned and the ODTR (See 11.3.7 below).
Note: Twelve NUSCs have been defined, within the 172-174 ranges, in Ireland.
Network Operator
