Canadian NPA 600 NXX Code Assignment Guideline
|
|
|
Reference: 8698-C12-200515976
|
|
1.
|
In the early 1990s, the North American Numbering Plan Administrator (NANPA) assigned numbering plan area (NPA) 600 to Canada as a Canada-specific NPA for use with non-geographic services. However, no guidelines were created for the assignment of central office codes (NXXs) within this NPA by the Canadian Numbering Administrator (CNA). NXX codes in NPA 600 are not associated with exchange areas in the same manner as NXX codes in geographic NPAs - such as NPA 514 in the Montreal Exchange Area. NXX codes in NPA 600 are associated with the geographic area covered by Canada and calls to telephone numbers in NPA 600 may terminate anywhere in the country.
|
|
2.
|
On 6 October 2004, the Canadian Steering Committee on Numbering (CSCN) initiated a process to develop guidelines for the assignment of NXXs within NPA 600. On 22 June 2005, the CSCN recommended that the resulting Canadian NPA 600 NXX Code Assignment Guideline (the Guideline) be accepted by the CRTC Interconnection Steering Committee (CISC). CISC subsequently approved the Guideline and forwarded it to the Commission on 12 August 2005 for its consideration.

|
The Guideline describes and specifies procedures for the assignment and administration of NXX codes within NPA 600 and any other NPAs that may be assigned in the future as Canada-specific non-geographic NPA codes.

|
4.
|
Following its review of the document, the Commission approves the NPA 600 NXX Code Assignment Guideline with the following modifications:
|
|
|
Paragraph 1.5 should be replaced with:
|
|
|
"Interconnection, routing, rating and settlements are not covered by this Guideline."
|
|
|
Paragraph 2.4 should be replaced with:
|
|
|
"Implementation of the technical changes in networks necessary to activate NPA 600 NXX code assignments is not covered by this Guideline."
|
|
|
Paragraph 5.6 should be replaced with:
|
|
|
"TSPs are not required to enter routing and rating information into the Telcordia® Business Integrated Routing and Rating Database System (BIRRDS) or to publish it in the Telcordia® LERGT Routing Guide."
|
|
|
Paragraph 5.10 should be replaced with:
|
|
|
"The CNA shall not disclose to the CSCN any information filed in confidence by the Code Holders or Code Applicants, unless the CRTC directs otherwise."
|
|
|
Paragraph 6.14 should be deleted.
|
|
|
Paragraph 9.3 should be replaced with:
|
|
|
"If and when the CNA advises the CRTC and the CSCN that one of the above thresholds has been reached, the CSCN and the CNA shall review the situation and prepare a consensus report outlining the appropriate option from the following list to be used for NPA 600 NXX Code forecasting. This report shall be forwarded to the CRTC, via CISC, for Commission approval.
|
|
|
The forecasting options are:
|
|
|
a) continue existing forecast process and reset thresholds;
|
|
|
b) modify forecasting process to require regular forecasts from all NPA 600 NXX Code Holders and prospective Code Holders; and
|
|
|
c) modify the Canadian C-NRUF process to include NPA 600.
|
|
|
In the event that a consensus cannot be reached, the CSCN is to follow the CISC dispute procedures."
|
|
|
In the Glossary section of the Guideline, the definition of the National Exchange Carriers Association should be replaced with:
