Designation of interconnecting routes are of great importance for identification and information. Technical developments, especially those due to digital technology, have brought a much greater variety of techniques and allow for a more efficient use of equipment.
Information on the equipment and techniques used is of great interest to staff working in the field of maintenance and operation. Present operational conditions can be more complicated than those previously, e.g. as a consequence of greater competition in the field of telecommunication. Another consideration is automated file handling which is often a necessity for network operators/service providers and the standardization of designation is an important factor to facilitate this.
The proper use of ITU-T Recommendation M.1400 â âDesignations for interconnections among network operatorsâ requires the identification of the operators sharing the interconnection. To that end an overall list of operators working in a country, with an officially recognized and standardized code for each of them, is of great help. It enables them to identify each other in a comprehensive and unique way. This will eventually result in one integrated database for all connections, in turn improving network operations and administration to the benefit of both providers and clients.
A centralized List of ITU Carrier Codes (ICCs) has been created with the ITU/TSB as the repository. All domestic and international carriers are expected to register with ITU/TSB for a carrier code. Instead of individual operators sending their ICCs to the TSB for registration, the national regulatory authorities are requested to provide the validated codes and related information of domestic network operators directly to the TSB. This list may be used to identify the operators while completing layer 2 records, related information, as explained in paragraph 8.3, 13.3 and 20.3 of ITU-T Recommendation M.1400.
The national authority in each country is requested to:
