Telecom Decision CRTC 2008-42

  Ottawa, 23 May 2008

CRTC Interconnection Steering Committee - Consensus items

  Reference: 8621-C12-01/00
  In this Decision, the Commission approves, with one change, consensus reports regarding several numbering issues.


The Canadian Steering Committee on Numbering (CSCN) of the CRTC Interconnection Steering Committee (CISC) submitted consensus reports to the CISC Steering Committee (SC).


On 2 May 2008, the SC approved the following reports and subsequently referred them to the Commission for consideration:
  • CSCN TIF Report 70 re: TIF 75 - CSCN Guidelines Review - Review of Canadian Adjunct to the INC Personal Communications Services (PCS) 5YY NXX Code Assignment Guidelines, 8 April 2008 (CNRE070A). The CSCN reached consensus on a Canadian Adjunct to the Industry Numbering Committee Personal Communications Services 5YY NXX Code Assignment Guidelines.
  • CSCN TIF Report 71 re: TIF 76 Additional Modifications to the Canadian MIN Block Identifier (MBI) Assignment Guideline, 8 April 2008 (CNRE071A). The CSCN reached consensus on Modifications to the Canadian Mobile Identification Numbers Block Identifier to adjust certain aspects of the MBI assignment guidelines concerning wireless carriers.
  • CSCN TIF Report 72 re: Recommendations regarding Relief Planning for NPAs 902 and 289/905, 17 April 2008 (CNRE072A). The CSCN reached consensus to suspend relief planning for numbering plan area (NPA) 902. The CSCN also reached consensus that the Canadian Numbering Administrator (CNA) should not consider any split options1 in the initial planning document for NPA 289/905 relief.


The reports are available on the Commission's website at

Commission's analysis and determination


As noted above, in CNRE072A the CSCN recommended that the CNA initial planning document not include any split options for the relief of NPA 289/905. CSCN argued that NPA 905 was previously relieved by NPA 289 using a distributed overlay and that using a split option would result in negative impacts on customers and carriers.


Although not discounting the CSCN arguments, the Commission is of the view that the CNA should not limit its choice of options when planning for the relief of exhausted NPAs. The Commission therefore directs the CNA to consider all options for the relief of NPA 289/905.



The Commission approves consensus reports CNRE070A and CNRE071A.


The Commission approves consensus report CNRE072A with the change noted above.

1 New area codes are normally added in one of two ways: a split or an overlay. An exhausting area code may be "split" into two or more parts. One of these parts would retain the original area code while a new area code would be assigned to the other part or parts.
