CNA
NPA Relief Planning Principles and
Considerations
• The NPA relief plan chosen will seek to
minimize end users’ confusion while
balancing the cost of implementation
by all affected parties.
• If a relief plan requires customers to
undergo number changes, the plan
shall not require these customers to
undergo further number changes until
at least 8-10 years later.
• All efforts should be made to choose a
plan that does not favour a particular
interest group, i.e., no relief plan
should give one Carrier or group of
Carriers a competitive advantage over
other Carriers or groups of Carriers.
CNA
NPA Relief Planning Principles and
Considerations (cont’d)
• The NPA Code Relief Coordinator
should facilitate the selection of a
consensus NPA relief plan based on
input as outlined below.
• Communications should be
established with all affected industry
members, the CRTC and the North
American Numbering Plan
Administrator (NANPA). This should be
initiated immediately after the need for
NPA Relief has been determined.
CNA
NPA Relief Planning Process
• The NPA Relief Planning process is
described in detail in the Canadian
NPA Relief Planning Guideline.
• This process requires participation by
Affected Parties and other interested
parties at meetings of the Relief
Planning Committee (RPC) for the
NPA requiring relief.
• The major objective of the NPA relief
planning process is to ensure an
adequate supply of CO Codes is
available at all times to the Canadian
telecommunications industry (i.e.,
ensure that NPA Relief occurs in
advance of NPA exhaust).
CNA
NPA Relief Planning Process (cont’d)
• Another objective of the NPA Relief
Planning process is to develop, in
accordance with the Canadian NPA
Relief Planning Guideline and its time
frames, a consensus recommendation
for an NPA relief plan to be submitted
for CRTC approval.
• It is the responsibility of all participants
(e.g. Carriers, service providers,
manufacturers, equipment suppliers,
and users) to implement the approved
NPA relief plan.
CNA
NPA Relief Planning Process (cont’d.)
• The Relief Options shall cover a period
of at least eight years beyond the
Projected Exhaust Date, and shall
cover more than one relief activity, if
necessary, during the time frame.
• The relief plan shall be a living
document and will reflect changes that
take place over time such as demand
for CO Codes or other factors (e.g.,
local competition, wireline and wireless
number portability, etc.) during the time
it takes to create. The annual and relief
planning NRUF analyses shall be used
as one of the tools in updating the
options.
CNA
NPA Relief Planning Process (cont’d.)
• The recommendation for a Relief
Method (e.g., split, overlay, boundary
realignment) is made by the RPC, and
shall be specified in the Planning
Document, along with boundaries if a
split is chosen. The estimated life of
the relief shall be included in the
Planning Document along with
assumptions, projected code
assignment rates, etc.
• If a Relief Option requires customers to
undergo number changes, the option
shall not require these customers to
undergo further number changes for at
least 8-10 years.
CNA
NPA Relief Planning Process (cont’d.)
• In the long term, the plan shall result in
the most effective use possible of all
CO Codes serving a given area.
Ideally, in the case of splits, all of the
CO Codes in a given area shall
exhaust at approximately the same
time. In practice this may not be
possible, but severe imbalances shall
be avoided.
CNA
The Roles and Responsibilities of the
CNA in the NPA Relief Planning

appropriate regulatory authority
CNA
The Roles and Responsibilities of the
CNA in the NPA Relief Planning
Process (cont’d)

Background
• NPA 902 serves 173 Exchange Areas
• NPA 902 serves the provinces of Nova
Scotia and Prince Edward Island
• Most of the growth for existing service
providers in area code 902 is
concentrated in less than ten (10)
Exchange Areas, with the majority of
this growth being in the Exchange
Areas of Antigonish, Bridgewater,
Charlottetown, Halifax, Kentville, New
Glasgow, Summerside, Sydney and
Yarmouth
• Projected Future Average Growth is 23
NXXs/year
• NPA 902 is projected to exhaust in
May 2015

Impacts
•
Customers
– in preparation for the assignment of CO Codes and
telephone numbers in the new/extended NPA, customers
must accommodate the additional NPA in their lists,
tables, systems and equipment
– if a split is implemented, telephone number changes to a
new NPA would create major impacts on lists, tables,
equipment, systems, advertising, etc.
