Common use of Transit Service Clause in Contracts

Transit Service. 12.1 As used in this Section, Transit Service is Telephone Exchange Service traffic that originates on Carrier's network, and is transported through Frontier’s Tandem to the subtending End Office or its equivalent of another carrier (CLEC, ILEC other than Frontier, Commercial Mobile Radio Service (CMRS) carrier, or other LEC (“Other Carrier”), when neither the originating nor terminating customer is a Customer of Frontier. For the avoidance of any doubt, under no circumstances shall Frontier be required to transit traffic through a Frontier Tandem to an End Office that does not have local Interconnection facilities and direct trunks to that particular Frontier Tandem. Switched Exchange Access Service traffic is not Transit Service. 12.1.1 If Carrier provides service using an NPA-NXX assigned to a rate center where Frontier provides extended area service or an applicable regulatory authority approved optional calling plan, and Carrier chooses to indirectly interconnect by using the tandem switching facilities of a third party, Frontier will have no obligation to route and rate traffic to Carrier’s NPA-NXX as an EAS call or pursuant to an optional calling plan unless Carrier has established a trunking and transiting arrangement for this traffic with Frontier and the other telecommunications carrier(s) utilizing the trunk and providing transiting service for the traffic. 12.2 Transit Service provides Carrier with the transport of Transit Service as provided below. 12.3 Transit Service may be routed over the Interconnection Trunks described in Sections 2 through 6 of this Attachment. Carrier shall deliver each Transit Service call to Frontier’s Tandem with CCS and the appropriate Transactional Capabilities Application Part (“TCAP”) message to facilitate full interoperability of CLASS Features and billing functions. 12.3.1 Carrier may use Transit Service only for traffic that originates on Carrier’s network and only to send traffic to an Other Carrier with whom Carrier has a reciprocal traffic exchange arrangement (either via written agreement or mutual tariffs) that provides for the Other Carrier, to terminate or complete traffic originated by Carrier and to xxxx Xxxxxxx, and not to bill Frontier, for such traffic. Xxxxxxx agrees not to use Frontier’s Transit Service to send traffic to an Other Carrier with whom Xxxxxxx does not have such a reciprocal traffic exchange arrangement or to send traffic that does not originate on Carrier’s network. 12.4 Carrier shall pay Frontier for Transit Service at the rates specified in the Pricing Attachment. Frontier will not be liable for compensation to any Other Carrier for any traffic that is transported through Frontier’s Tandem and Frontier reserves the right to assess to Carrier any additional charges or costs any Other Carrier imposes or levies on Frontier for the delivery or termination of such traffic, including any Switched Exchange Access Service charges. If Frontier is billed by any Other Carrier for any traffic originated by Carrier, Frontier may provide notice to Carrier of such billing. Upon receipt of such notice, Carrier shall immediately stop using Frontier’s Transit Service to send any traffic to such Other Carrier until it has provided to Frontier certification that the Other Carrier has removed such billed charges from its bill to Frontier and that the Other Carrier will not bill Frontier for any traffic originated by Carrier. Such certification must be signed by an authorized officer or agent of the Other Carrier and must be in a form acceptable to Frontier. 12.5 If Carrier uses Transit Service for traffic volumes that exceed the Centum Call Seconds (Hundred Call Seconds) busy hour equivalent of 200,000 combined minutes of use per month (a DS1 equivalent) to the subtending End Office of a particular Other Carrier for any month (the “Threshold Level”). Carrier shall use good faith efforts to establish direct interconnection with such Other Carrier and reduce such traffic volumes below the Threshold Level. If Frontier believes that Xxxxxxx has not exercised good faith efforts promptly to obtain such direct interconnection, either Party may use the Dispute Resolution processes of this Agreement. 12.6 If Carrier fails to comply with Section 12 of this Attachment, such failure shall be a material breach of a material provision of this Agreement and Frontier may exercise any and all remedies under this Agreement and Applicable Law for such breach. 12.7 If or when a third party carrier plans to subtend a Carrier switch, then Carrier shall provide written notice to Frontier at least ninety (90) days before such subtending service arrangement becomes effective so that Frontier may negotiate and establish direct interconnection with such third party carrier. Upon written request from Frontier, Carrier shall offer to Frontier a service arrangement equivalent to or the same as Transit Service provided by Frontier to Carrier as defined in this Section such that Frontier may terminate calls to a Central Office or its equivalent of a CLEC, ILEC other than Frontier, CMRS carrier, or other LEC, that subtends a Carrier Central Office or its equivalent (“Reciprocal Tandem Transit Service”). Carrier shall offer such Reciprocal Transit Service arrangements under terms and conditions of an amendment to this Agreement or a separate agreement no less favorable than those provided in this Section. 12.8 Neither Party shall take any actions to prevent the other Party from entering into a direct and reciprocal traffic exchange arrangement with any carrier to which it originates, or from which it terminates, traffic.

If Frontier believes that Xxxxxxx CTI has not exercised good faith efforts promptly to obtain such direct interconnection, either Party may use the Dispute Resolution processes of this Agreement. 12.6 13.6 If Carrier CTI fails to comply with Section 12 13 of this Attachment, such failure shall be a material breach of a material provision of this Agreement and Frontier may exercise any and all remedies under this Agreement and Applicable Law for such breach. 12.7 13.7 If or when a third third-party carrier plans to subtend a Carrier a/an CTI switch, then Carrier CTI shall provide written notice to Frontier at least ninety (90) days before such subtending service arrangement becomes effective so that Frontier may negotiate and establish direct interconnection with such third third-party carrier. Upon written request from Frontier, Carrier CTI shall offer to Frontier a service arrangement equivalent to or the same as Transit Service provided by Frontier to Carrier CTI as defined in this Section such that Frontier may terminate calls to a Central Office or its equivalent of a CLEC, ILEC other than Frontier, CMRS carrier, or other LEC, that subtends a Carrier Central Office or its equivalent (“Reciprocal Tandem Transit Service”). Carrier a/an CTI CTI shall offer such Reciprocal Transit Service arrangements under terms and conditions of an amendment to this Agreement or a separate agreement no less favorable than those provided in this Section. 12.8 13.8 Neither Party shall take any actions to prevent the other Party from entering into a direct and reciprocal traffic exchange arrangement with any carrier to which it originates, or from which it terminates, traffic.
