Tandem Switching 4.5.1 The Tandem Switching capability Network Element is defined as:
(i) trunk-connect facilities, which include, but are not limited to, the connection between trunk termination at a cross-connect panel and switch trunk card; (ii) the basic switch trunk function of connecting trunks to trunks; and (iii) the functions that are centralized in the Tandem Switches (as distinguished from separate end office switches), including but not limited to call recording, the routing of calls to operator services and signaling conversion features.
4.5.2 Where <<customer_short_name>> utilizes portions of the BellSouth network in originating or terminating traffic, the Tandem Switching rates are applied in call scenarios where the Tandem Switching Network Element has been utilized. Because switch recordings cannot accurately indicate on a per call basis when the Tandem Switching Network Element has been utilized for an interoffice call originating from a UNE port and terminating to a BellSouth, Independent Company or Facility-Based CLEC office, BellSouth has developed, based upon call studies, a melded rate that takes into account the average percentage of calls that utilize Tandem Switching in these scenarios. BellSouth shall apply the melded Tandem Switching rate for every call in these scenarios. BellSouth shall utilize the melded Tandem Switching Rate until BellSouth has the capability to measure actual Tandem Switch usage in each call scenario specifically mentioned above, at which point the rate for the actual Tandem Switch usage shall apply. The UNE Local Call Flows set forth on BellSouth's website, as amended from time to time and incorporated herein by this reference, illustrate when the full or melded Tandem Switching rates apply for specific scenarios.
Tandem Transit Traffic
12.1 As used in this Section, Tandem Transit Traffic is Telephone Exchange Service traffic that originates on Onvoy'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”). Neither the originating nor terminating customer is a Customer of Frontier. Subtending End Offices shall be determined in accordance with and as identified in the Local Exchange Routing Guide (LERG). For the avoidance of any doubt, under no circumstances shall Frontier be required to transit traffic through a Frontier Tandem to a Central Office that the LERG does not identify as subtending that particular Frontier Tandem. Switched Exchange Access Service traffic is not Tandem Transit Traffic.
12.2 Tandem Transit Traffic Service provides Onvoy with the transport of Tandem Transit Traffic as provided below.
12.3 Tandem Transit Traffic may be routed over the Interconnection Trunks described in Sections 2 through 6 of this Attachment. Onvoy shall deliver each Tandem Transit Traffic 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.
12.4 Onvoy may use Tandem Transit Traffic Service only for traffic that originates on Onvoy’s network and only to send traffic to an Other Carrier with whom Onvoy 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 Onvoy and to bill Onvoy, and not to bill Frontier, for such traffic. Onvoy agrees not to use Frontier’s Tandem Transit Traffic Service to send traffic to an Other Carrier with whom Onvoy does not have such a reciprocal traffic exchange arrangement or to send traffic that does not originate on Onvoy’s network.
12.5 Onvoy shall pay Frontier for Tandem Transit Traffic 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 Onvoy 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 Onvoy, Frontier may provide notice to Onvoy of such billing. Upon receipt of such notice, Onvoy shall immediately stop using Frontier’s Tandem Transit Traffic 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 Onvoy. Such certification must be signed by an authorized officer or agent of the Other Carrier and must be in a form acceptable to Frontier.
12.6 If Onvoy uses Tandem Transit Traffic 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”). Onvoy 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 Xxxxx has not exercised good faith efforts promptly to obtain such direct interconnection, either Party may use the Dispute Resolution processes of this Agreement.
12.7 If Onvoy 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.
12.8 If or when a third party carrier plans to subtend an Onvoy switch, then Onvoy 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, Onvoy shall offer to Frontier a service arrangement equivalent to or the same as Tandem Transit Traffic Service provided by Frontier to Onvoy 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 an Onvoy Central Office or its equivalent (“Reciprocal Tandem Transit Service”). Onvoy 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.
12.9 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.
Local Circuit Switching Capability, including Tandem Switching Capability 4.1.3.1 Definition
4.1.3.2 Notwithstanding BellSouth’s general duty to unbundle local circuit switching, BellSouth shall not be required to unbundle local circuit switching for <<customer_name>> when <<customer_name>> serves end-users with four (4) or more voice-grade (DS-0) equivalents or lines in locations served by BellSouth’s local circuit switches, which are in the following MSAs: Atlanta, GA; Miami, FL; Orlando, FL; Ft. Lauderdale, FL; Charlotte-Gastonia-Rock Hill, NC; Greensboro-Winston Salem-High Point, NC; Nashville, TN; and New Orleans, LA, and BellSouth has provided non-discriminatory cost based access to the Enhanced Extended Link (EEL) throughout Density Zone 1 as determined by NECA Tariff No. 4 as in effect on January 1, 1999.
4.1.3.3 In the event that <<customer_name>> orders local circuit switching for a single end user account name at a single physical end user location with four (4) or more 2-wire voice-grade loops from a BellSouth central office in an MSA listed above, BellSouth shall charge <<customer_name>> the market based rate in Exhibit C for use of the local circuit switching functionality for the affected facilities.
4.1.3.4 A featureless port is one that has a line port, switching facilities, and an interoffice port. A featured port is a port that includes all features then capable or a number of then capable features specifically requested by <<customer_name>>. Any features that are not currently then capable but are technically feasible through the switch can be requested through the NBR/BFR process.
4.1.3.5 BellSouth will provide to <<customer_name>> customized routing of calls: (i) to a requested directory assistance services platform; (ii) to an operator services platform pursuant to Section 10 of Attachment 2; (iii) for <<customer_name>>’s PIC’ed toll traffic in a two (2) PIC environment to an alternative OS/DA platform designated by <<customer_name>>. <<customer_name>> customers may use the same dialing arrangements as BellSouth customers.
4.1.3.6 Remote Switching Module functionality is included in Switching Capability. The switching capabilities used will be based on the line side features they support.
4.1.3.7 Switching Capability will also be capable of routing local, intraLATA, interLATA, and calls to international customer’s preferred carrier; call features (e.g. call forwarding) and Centrex capabilities.
4.1.3.8 Where required to do so in order to comply with an effective Commission order, BellSouth will provide to <<customer_name>> purchasing local BellSouth switching and reselling BellSouth local exchange service under Attachment 1, selective routing of calls to a requested directory assistance services platform or operator services platform. <<customer_name>> customers may use the same dialing arrangements as BellSouth customers, but obtain a <<customer_name>> branded service.
Local Switching 4.1.1 BellSouth shall provide non-discriminatory access to local circuit switching capability, and local tandem switching capability, on an unbundled basis, except as set forth below in Section 4.1.
Switching System Hierarchy and Trunking Requirements For purposes of routing ECI traffic to Verizon, the subtending arrangements between Verizon Tandem Switches and Verizon End Office Switches shall be the same as the Tandem/End Office subtending arrangements Verizon maintains for the routing of its own or other carriers’ traffic (i.e., traffic will be routed to the appropriate Verizon Tandem subtended by the terminating End Office serving the Verizon Customer). For purposes of routing Verizon traffic to ECI, the subtending arrangements between ECI Tandem Switches and ECI End Office Switches shall be the same as the Tandem/End Office subtending arrangements that ECI maintains for the routing of its own or other carriers’ traffic.
Originating Switched Access Detail Usage Data A category 1101XX record as defined in the EMI Telcordia Practice BR-010-200- 010.
Local Traffic Traffic that is originated by a Customer of one Party on that Party’s network and terminates to a Customer of the other Party on that other Party’s network within Verizon's then current local calling area (including non-optional local calling scope arrangements) as defined in Verizon’s effective Customer Tariffs. A non- optional local calling scope arrangement is an arrangement that provides Customers a local calling scope (Extended Area Service, “EAS”), beyond their basic exchange serving area. Local Traffic does not include optional local calling scope traffic (i.e., traffic that under an optional rate package chosen by the Customer terminates outside of the Customer’s basic exchange serving area). IntraLATA calls originated on a 1+ presubscription basis, or on a casual dialed (10XXX/101XXXX) basis are not considered Local Traffic. Local Traffic does not include any Internet Traffic.
Signaling Link Transport 9.2.1 Signaling Link Transport is a set of two or four dedicated 56 kbps transmission paths between Global Connection-designated Signaling Points of Interconnection that provide appropriate physical diversity.
Transit Traffic 7.2.2.3.1 CenturyLink will accept traffic originated by CLEC’s network and/or its end user(s) for termination to other Telecommunications Carrier’s network and/or its end users that is connected to CenturyLink's Switch. CenturyLink will also terminate traffic from these other Telecommunications Carriers’ network and/or its end users to CLEC’s network and/or its end users. For purposes of the Agreement, transit traffic does not include traffic carried by Interexchange Carriers. That traffic is defined as Jointly Provided Switched Access.
7.2.2.3.2 The Parties involved in transporting transit traffic will deliver calls to each involved network with CCS/SS7 protocol and the appropriate ISUP/TCAP messages to facilitate full Interoperability and Billing functions.
7.2.2.3.3 The originating company is responsible for payment of appropriate rates to the transit company and to the terminating company. The Parties agree to enter into traffic exchange agreements with third party Telecommunications Carriers prior to delivering traffic to be transited to third party Telecommunications Carriers. In the event one Party originates traffic that transits the second Party’s network to reach a third party Telecommunications Carrier with whom the originating Party does not have a traffic exchange agreement, then the originating Party will indemnify, defend and hold harmless the second Party against any and all charges levied by such third party Telecommunications Carrier, including any termination charges related to such traffic and any attorneys fees and expenses. In the case of IntraLATA LEC Toll traffic where CenturyLink is the designated IntraLATA Toll provider for existing LECs, CenturyLink will be responsible for payment of appropriate usage rates.
7.2.2.3.4 When CenturyLink receives an unqueried call from CLEC to a telephone number that has been ported to another local services provider, the transit rate will apply in addition to any query rates.
7.2.2.3.5 In the case of a transit call that terminates in the Local Calling Area but in a different state than the call originated, and the CLEC does not have an agreement with CenturyLink in the state where the transit call terminated, CLEC must execute an agreement for that state if it is a state served by CenturyLink. In the absence of a second agreement, the transit rate in Exhibit A of this Agreement will be billed to the CLEC.
Switching All of the negotiated rates, terms and conditions set forth in this Section pertain to the provision of local and tandem switching.
