Tandem Trunking Sample Clauses

The Tandem Trunking clause defines the rules and procedures for routing telecommunications traffic through intermediate switching points, known as tandem switches, rather than directly between originating and terminating points. In practice, this clause specifies when and how calls or data transmissions are routed via these tandem trunks, often to optimize network efficiency or manage capacity. For example, if direct trunk lines are unavailable or congested, traffic may be rerouted through a tandem switch to reach its destination. The core function of this clause is to ensure reliable and efficient network operation by providing alternative routing options, thereby reducing the risk of service interruptions and optimizing resource use.
Tandem Trunking. AT&T SOUTHEAST REGION 9-STATE 4.3.3.3.1 Section 251(b)(5)/IntraLATA Toll Traffic shall be routed on Local Interconnection Trunk Groups established at each AT&T SOUTHEAST REGION 9-STATE Access Tandem in the LATA where CLEC homes its NPA/NXX codes for calls destined to or from all AT&T SOUTHEAST REGION 9-STATE End Offices that subtend the designated Tandem. These trunk groups shall be one-way except where two-way trunks have been mutually agreed and will utilize SS7 signaling. Where CLEC does not interconnect at every Access Tandem switch location in the LATA, CLEC must use Multiple Tandem Access (MTA) to route traffic to End Users through those Tandems within the LATA to which CLEC is not interconnected. To utilize MTA, CLEC must establish Local Interconnection Trunk Groups to a minimum of one (1) Access Tandem within each LATA as required. AT&T SOUTHEAST REGION 9-STATE will route CLEC originated 251(b)(5)/IntraLATA Toll traffic for LATA-wide transport and termination. Compensation for MTA is described in Section 6.2.9 below.

  • 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 ▇▇▇▇▇ 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.

  • Unbundled Network Element Combinations 5.1. Unbundled Network Element Combinations shall include: 1) Enhanced Extended Links (EELs); 2) UNE Loops/Special Access Combinations; 3) Loop/Port Combinations; and 4)

  • 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.

  • Unbundled Channelization (Multiplexing) 5.7.1 To the extent NewPhone is purchasing DS1 or DS3 or STS-1 Dedicated Transport pursuant to this Agreement, Unbundled Channelization (UC) provides the optional multiplexing capability that will allow a DS1 (1.544 Mbps) or DS3 (44.736 Mbps) or STS-1 (51.84 Mbps) Network Elements to be multiplexed or channelized at a BellSouth central office. Channelization can be accomplished through the use of a multiplexer or a digital cross-connect system at the discretion of BellSouth. Once UC has been installed, NewPhone may request channel activation on a channelized facility and BellSouth shall connect the requested facilities via COCIs. The COCI must be compatible with the lower capacity facility and ordered with the lower capacity facility. This service is available as defined in NECA 4. 5.7.2 BellSouth shall make available the following channelization systems and interfaces: 5.7.2.1 DS1 Channelization System: channelizes a DS1 signal into a maximum of twenty- four (24)
