Telecom Order CRTC 2002-405

Ottawa, 11 October 2002

Thunder Bay Telephone

Reference: Tariff Notice 99

Common channel signalling 7 transit service


The Commission received an application by Thunder Bay Telephone (TBT), dated 20 February 2002, to revise item 7, CCS7 Signalling Interconnection, under section TB230, Wireless Access Service, of its General Tariff, in order to introduce a common channel signalling 7 (CCS7) transiting service. TBT stated that this service would provide for the exchange of CCS7 signalling messages between TBT's CCS7 network and the wireless service providers' (WSPs) network.


The Commission received comments from Microcell Telecommunications Inc. (Microcell), dated 12 March 2002, requesting that TBT clarify the wording of the tariff application.


Microcell recommended specific language for item 7.06 (a) to make it clear that the traffic exchange would occur across a third party CCS7 network with which both the WSP and TBT have existing CCS7 link sets. Microcell also recommended that TBT delete proposed tariff items 7.06 (b) and (c) to avoid redundancy and misinterpretation. Finally, Microcell recommended that TBT indicate in either item 7.5 or 7.06 (f) when and where the administration charge of $69,500 would apply.


The Commission also received comments from Rogers Wireless Inc. (RWI), dated 15 March 2002, that supported TBT's application as well as the wording changes suggested by Microcell.


In reply, TBT agreed to modify item 7.06 (a) with the language recommended by Microcell and to delete items 7.06 (b) and (c). TBT did not address Microcell's concerns about when and where the "administration" service charge would apply.


The Commission notes that the terms and conditions proposed by TBT to provide this service are consistent with those approved by the Commission for other telephone companies. In the Commission's view, it is clear in the proposed tariff that the $69,500 administration charge would apply only if TBT were to provide the initial engineering, planning and testing with respect to interconnecting directly to TBT's gateway signalling transfer point (STP) connection. Further, the Commission notes that subscribing to TBT's transiting service would not require a gateway STP connection. The Commission finds that the proposed tariff is sufficiently specific with respect to the conditions under which the administration service charge applies.


In light of the above, the Commission approves TBT's application subject to the agreed upon wording changes being made. The revisions take effect as of the date of this order.


TBT is to issue revised tariff pages forthwith to reflect these changes.
