CISC Canadian Steering Committee on Numbering – Consensus reports CNRE102A, CNRE104A, and CNRE105A related to various numbering administration guidelines

  1. On 24 April 2014, the Canadian Steering Committee on Numbering (CSCN) of the CRTC Interconnection Steering Committee (CISC) submitted the following consensus reports for Commission approval, proposing certain changes:
    • Canadian MIN [Mobile Identification Number] Block Identifier (MBI) Assignment Guideline (CNRE102A)
    • Emergency Service Routing Digit (ESRD) Block Assignment Guideline (CNRE104A)
    • GTT [Global Title Transaction]Point Code Notification Process (CNRE105A)
  2. With regard to CNRE102A, the CSCN noted that it had updated the guideline to remove all references to troublesome block identifiers. The block identifiers contain bit patterns that sometimes produced minor degradation in analog control channel systems. This is no longer an issue because the associated equipment has been removed from all carriers’ networks.
  3. For CNRE104A, the CSCN proposed to include provisions to address changes to ESRDs or the return of ESRDs to the assignment pool, along with improved definitions for certain terms listed in the Glossary section of the guideline. Currently these guidelines only include provisions for the initial assignment of ESRDs.
  4. Regarding CNRE105A, the forms that are currently available to facilitate the exchange of point code information are not being used as originally anticipated and different notification templates have been created by various service providers. The CSCN therefore requested Commission approval of a revised GTT Point Code notification process.
  5. These consensus reports can be found in the “Reports” section of the CSCN page, which is available in the CISC section of the Commission’s website at
  6. The Commission has reviewed and approves the above-noted consensus reports and guidelines.
