Ottawa, 18 June 2001

|
Providing relief for the diminishing supply of telephone numbers
in area codes 613 and 819 |
|
Reference: 8698-C12-16/01 |
|
Telephone numbers in area codes 613 and 819 will soon be
depleted. Solutions and recommendations for a relief plan have been
identified by a subcommittee of the CRTC Industry Steering
Committee. This public notice invites comments on solutions and
recommendations in determining the appropriate relief method(s) and
date(s) for these area codes. Parties who wish to provide comments
are requested to submit their responses to this public notice by 8
August 2001. |
1. |
Area code 613 serves a large portion of eastern Ontario,
including Ottawa, Belleville, Brockville, Cornwall, Kingston and
Pembroke.
|
2. |
Area code 613 is divided into 131 telephone company exchanges.
Customers in 37 of these exchanges have local seven-digit dialing to
exchanges on the Quebec side of the Ottawa River in area code 819.
Almost all of these exchanges (36 out of 37) have local seven-digit
dialing to exchanges in the city of Hull and the surrounding area. |
3. |
Area code 819 serves most of western and northern Quebec,
including Hull, Drummondville, Shawinigan, Sherbrooke,
Trois-Rivières and Victoriaville. |
4. |
Area code 819 is divided into 213 telephone company exchanges.
Customers in 19 of these exchanges have local seven-digit dialing to
exchanges on the Ontario side of the Ottawa River in area code 613.
Almost all of these exchanges (18 out of 19) have local seven-digit
dialing to exchanges in the city of Ottawa and the surrounding areas
of area code 613. |
|
Area code exhaust |
5. |
An area code exhausts when no additional central office codes
(i.e., the first three digits of a seven-digit telephone number)
are available for assignment to a telecommunications service
provider. |
6. |
Central office codes are assigned by the Canadian Numbering
Administrator (CNA) for use by telecommunications service providers
in a particular exchange to meet their customers' demand for
telephone numbers. |
7. |
With the introduction of new telecommunications technologies in
recent years, the demand for new numbers has increased dramatically.
As a result, the supply of telephone numbers available to service
providers - and their customers - decreases and more central
office codes are required. Area code exhaust occurs when no more
central office codes are available for assignment. |
8. |
Every year, the CNA conducts a survey of service providers
operating in all Canadian area codes to determine when area code
exhaust will occur, and when relief planning should begin. |
9. |
In August 2000, the CNA completed a more detailed survey of
service providers operating in area codes 613 and 819. This survey
provides information on the actual number of central office codes
assigned to each carrier in these two area codes, as well as a
forecast of their needs over the next five years. The results of
this survey indicated that area code 613 would exhaust in January
2006 and area code 819 would exhaust in January 2005. |
10. |
In February 2001, the CNA conducted its annual survey of all area
codes. This survey indicates that the exhaust of area code 613 may
not occur until August 2007 and the exhaust of area code 819 may not
occur until March 2007. |
|
Protected codes |
11. |
The 613 and 819 area codes are somewhat unique in that the
local calling area in the Ottawa-Hull area overlaps two
provinces and two area codes, and is treated as a single
exchange by telecommunications networks. To permit seven-digit
local dialing between the two area codes, a particular central
office code can only be assigned in one of the two area codes
within the Ottawa-Hull local calling area. For example, if the
central office code "232" from area code 613 is
assigned in Ottawa, then central office code "232"
from area code 819 is not assigned in Hull. The central office
code that is not assigned in this case is called a
"protected" code. |
12. |
As of 1 January 2001, there were 64 protected codes in area
code 613, and 131 protected codes in area code 819. If these
codes were no longer protected, they would become available for
assignment and would delay exhaust of these area codes. |
13. |
Based on the survey conducted in August 2000, the CNA estimates
that the release of these protected codes would defer exhaust of
area code 613 to 2008 and area code 819 to 2024. The 2001 annual
survey indicates that the release of these protected codes may defer
exhaust of area code 613 to 2011 and 819 to 2022. |
14. |
- The release of these protected codes would require that local
calls placed between these two area codes include the area code
of the number being dialed, i.e., ten-digit local dialing.
|
|
Area code relief methods
|
15. |
- Area code relief involves the addition of a new area code to
part or all of the region served by the original area code. The
addition of a new area code requires a great deal of work on the
part of both telecommunications service providers and their
customers. In order to ensure that telephone numbers continue to
be available, relief normally takes place 12 to 18 months prior
to exhaust. This schedule also allows for some volatility in
case demand should unexpectedly increase.
|
16. |
It is important to note that area code relief planning does not
alter local and long distance calling areas, or rates. |
|
Two types of area code relief methods
|
17. |
- New area codes are normally added in one of two ways: a split
or an overlay.
|
|
Splitting an area code
|
18. |
- 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. Since central office codes are assigned to telephone
company exchanges, area codes are almost always split along the
boundaries of these exchanges to minimize technical difficulties
and confusion for service providers and customers. It is also
important to split area codes along clearly defined boundaries
such as municipalities, major roads or geographic landmarks so
that these boundaries are easily recognized by customers.
|
19. |
- Customers in exchanges that become part of the new area code
retain the same seven-digit telephone numbers. However, the new
area code replaces the original area code as the first three
digits of the full ten-digit number. Depending on how an area
code is split, customers in both the new and original area codes
may be able to retain local seven-digit dialing within the area
code. Local calls placed between area codes, however, would
require ten-digit dialing.
|
20. |
Implementation of an area code split requires a "permissive
dialing period". During this period, local calls placed to
customers in the new area code may be placed using either the new or
the original area code. In addition, customers who dial using the
other party's original area code may hear a message reminding the
customer that, in future calls, they should use the new area code.
Any equipment that may be affected by this message must be made
ready before this message is introduced. |
21. |
- The "permissive dialing period" provides time for
customers and service providers to reprogram or upgrade
equipment (e.g., cellular handsets, speed dial lists,
auto-dialers, security alarms, etc.) to handle the new area code
and, where required, accommodate local 10-digit dialing. Once
the permissive dialing period is over, calls that are not dialed
using the correct area code will not be routed correctly, or may
be routed to the wrong telephone number. All necessary changes
to customer and network equipment must be completed before the
end of the permissive dialing period.
|
|
Overlaying an area code
|
22. |
- Part or all of an exhausting area code may also be
"overlaid" with a new area code or area codes instead
of splitting the area code. In this case, the new area code is
added to some or all of the exchanges served by the existing
area code. Central office codes from this new area code may be
assigned for use by service providers operating in the
"overlaid" exchanges. A portion of an exhausting area
code may be overlaid with a new area code, for example, in order
to provide new resources to an area of very high demand.
|
23. |
- Since telephone numbers from two or more area codes may be in
use in a single exchange, all local calls must be dialed using
ten digits to ensure the call can be routed to the correct
destination. All existing telephone numbers would remain in the
same area code, although new telephone numbers may be assigned
from the new area code.
|
24. |
An area code overlay also requires a "permissive dialing
period". During this period, local calls may be placed using
either seven or ten digits. In addition, customers who place a call
using seven digits may hear a message reminding them to dial local
calls by using ten digits. Any equipment that may be affected by
this message must be made ready before this message is introduced. |
25. |
- As with an area code split, the "permissive dialing
period" for an overlay provides time for customers and
service providers to reprogram or upgrade equipment (e.g., speed
dial lists, auto-dialers, security alarms, etc.) to handle
ten-digit local dialing. Once the permissive dialing period is
over, local calls that are not dialed using ten digits will not
be routed correctly. All necessary changes to customer and
network equipment must be completed before the end of the
permissive dialing period.
|
|
Relief planning activities to date |
26. |
- In July 2000, Science Applications International Corporation (SAIC)
Canada, in its role as the CNA, announced that area codes 613
and 819 were projected to exhaust within five years. The CNA
also requested that service providers submit the necessary
information to complete a detailed survey of the anticipated
assignment of central office codes in these area codes.
|
27. |
- On 5 February 2001, the Commission issued Public Notice CRTC 2001-20, announcing the establishment of the Numbering Plan Area
(NPA or area code) 613/819 Relief Planning Committee as an ad
hoc committee of the CRTC Interconnection Steering Committee (CISC).
The public notice invited interested parties to participate in
meetings to identify solutions to the area code exhaust
situation. In addition, the Commission distributed an
information bulletin to municipal governments located in the
regions served by the 613 and 819 area codes.
|
28. |
At the first meeting of the Relief Planning Committee, the CNA
provided an initial planning document that identified a number of
alternatives to be considered in planning area code relief. |
29. |
- During a series of public meetings, the committee developed a
consensus planning document. This planning document includes an
analysis of all the options that could be implemented to provide
relief for exhaust in area codes 613 and 819, including those
recommended by the CNA as well as additional options identified
by the Committee. The planning document is attached to this
public notice.
|
30. |
The consensus planning document was approved by the CISC on 30
May 2001. |
|
The recommendations
|
31. |
- The recommendations contained in the Relief Planning
Committee's consensus planning document are summarized as
follows:
|
|
a) protected central office codes used to permit seven-digit
local dialing between area codes 613 and 819 should be released in
the fourth quarter of 2005. This will require the introduction of
ten-digit local dialing between NPAs 819 and 613.
|
|
b) the relief date for area code 613 should tentatively be
scheduled for the fourth quarter of 2009.
|
|
c) relief of area code 613 should be implemented using an
overlay of all exchanges currently served by the existing area
code (i.e., a "distributed" overlay, as described in the
attached planning document).
|
|
d) if the protected codes in area code 819 are released, no
further relief of this area code needs to take place at this time.
|
|
How to submit your comments
|
32. |
- The Commission seeks input to:
|
|
a) identify solutions to the exhaust issue in the 613 and 819
area codes;
|
|
b) evaluate the options and recommendations developed by the
CISC Ad Hoc NPA 613/819 Relief Planning Committee and described in
the planning document (attached);
|
|
c) determine the effects of various relief options on
consumers, telecommunications service providers and all other
affected parties;
|
|
d) establish an appropriate relief date(s) for area codes 613
and 819; and
|
|
e) determine which relief option(s) is most appropriate to
alleviate the exhaust of area codes 613 and 819.
