RE:  Approval of emergency notification of shortened interval for rehoming of 25 CO Codes by SSi Micro Ltd.

Dear Mr. Muise:

By letter, dated 2 May 2018, SSi Micro Ltd. (SSi) requested that Commission staff approve an emergency notification for a reduction to the normal 45-day notification period for a change in the routing of these CO codes, which are currently in-service, to a different Toll Access Tandem (TAT).

SSi indicated that its Nunavut NPA-NXX was currently homed on the Bell Canada Toll Access Tandem (TAT) switch in Montreal (MTRLPQ0207T), based on an agreement between itself and Northwestel Inc. (Northwestel) that was filed with the CRTC on 22 December 2017. SSi noted that this homing arrangement was reflected in the Local Equipment Routing Guide (LERG) consistent with the Commission approved CO Code Assignment Guidelines.

SSi stated that it had been notified by Northwestel that the TAT had been changed from Montreal to Whitehorse (WHTHYTXB04T) and that Bell Canada has indicated that traffic sent to the Montreal TAT will be blocked.

Commission staff notes that calls routed according to the LERG, which currently has incorrect homing information, will result in dropped or incomplete calls by SSi customers.

Commission staff considers this request for an emergency notification for shortened intervals to be reasonable, and in the circumstance, approves an effective date of 1 June 2018.

SSi is reminded that, as per the Guideline, carriers are to make their best effort to implement these codes in the shorter timeframe, but are not obligated to implement the changes 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,
