Carriers may request test CO Codes in the relief NPA for test purposes within their own networks during the relief implementation timeframe, in accordance with the Canadian Central Office Code (NXX) Assignment Guideline. 9-1-1 Service The introduction of the new overlay NPA is not expected to have any impact on the dialling of the 911 abbreviated dialling number nor the routing of emergency calls to the appropriate Public Service Answering Point (PSAP). However, the introduction of the new overlay NPA may have an impact on 911 service, trunking and systems. Carriers who intend to provide service using CO Codes in the relief NPA or to port numbers into their switch from the relief NPA, shall establish 9-1-1 trunking and associated interconnection arrangements as per existing interconnection agreements. Carriers that provide 9-1-1 networking services to any PSAP shall establish 9-1-1 trunking and associated interconnection arrangements as per existing interconnection agreements. These arrangements shall be made prior to the relief date upon request of Carriers, and provided that these arrangements are in accordance with the timelines, terms and conditions set out in existing interconnection agreements. The existing procedure for implementing new Carrier trunk groups for 9-1-1 traffic, including testing with local Carriers 9-1-1 and PSAPs, should be used. All Carrier related changes that impact 9-1-1 must be completed in accordance with the Relief Implementation Schedule. Other N-1-1 Services Carriers should review routing to other N-1-1 numbers including 211, 311, 411, 511, 611, 711 and 811 as necessary to ensure that calls will be properly routed. Payphone Service Providers It is the responsibility of each Payphone Service Provider to update any system associated with the operation of payphones in order to accommodate the new overlay area code. As well, each Payphone Service Provider must update any instructions for using their payphones to advise customers regarding the new overlay area code if necessary. International Gateway Service Providers International Gateway Service Providers are responsible to implement changes to their network in order to accommodate the new overlay area code. It is recommended that Commission staff notify Canadian International Gateway Service Providers of the implementation of the new overlay area code.
