Subject: Approval of emergency notification for Toronto CO Code
Dear Karen Robinson,
On 12 April 2023, TELUS Integrated Communications (TELUS) requested that Commission staff approve an emergency notification for one central office (CO) code in the Toronto, Ontario Exchange Area with an effective date of 27 May 2023, rather than 66 days after the received date of a completed Part 1 Form, as specified in the Canadian Central Office code (NXX) Assignment Guideline (the Guideline). The request indicates the preferred CO Code to be 437-561.
TELUS indicated that these CO codes are required as their available numbering inventory has reached a critical level.
Commission staff considers the request for an emergency notification to be reasonable.
TELUS is reminded that, per the Guideline, carriers are to make their best efforts to implement the new CO codes in the shorter timeframe, but are not obligated to implement these CO codes in their networks in less than the normal minimum 45 day activation interval and, consequently, call blocking, routing errors and/or billing errors could occur.
Sincerely,
Original signed by
