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 Switching. 4.3.1 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.
Tandem Switching. The unbundled Tandem Switching Element includes trunk-connect facilities, the basic switching function of connecting trunks to trunks, and the functions that are centralized in Tandem Switches. Unbundled Tandem switching creates a temporary transmission path between interoffice trunks that are interconnected at a Verizon access Tandem for the purpose of routing a call or calls.
Tandem Switching. The trunk-connect facilities on a Verizon circuit switch that functions as a tandem switch, plus the functions that are centralized in that switch, including the basic switching function of connecting trunks to trunks, unbundled from and not contiguous with loops and transmission facilities. Tandem Switching creates a temporary transmission path between interoffice trunks that are interconnected at a Verizon tandem switch for the purpose of routing a call. A tandem switch does not provide basic functions such as dial tone service.
Tandem Switching compensation for the use of Tandem Switching consists of a call set-up rate element (per message) where applicable and a duration (per minute) rate element.
Tandem Switching compensation for the use of Tandem Switching consists of a duration charge (per minute) rate element.
Tandem Switching. DTI will charge DTI's IXC affiliate the following Switched Access elements on a meet-point basis:
Tandem Switching. 47.1. Sprint will offer unbundled Tandem Switching in conjunction with unbundled Local Circuit Switching only where the Commission or FCC determines that unbundled Local Circuit Switching is required to be provided. Where Sprint is no longer required to provide Tandem Switching CLEC will agree to a time line to transition from unbundled Tandem Switching within thirty (30) days of the Commission or FCC finding.
47.2. Tandem Switching is the function that establishes a communications path between two switching offices (connecting trunks to trunks) through a third switching office (the tandem switch). A host/remote end office configuration is not a Tandem Switching arrangement. Sprint will provide CLEC access to the same shared transport facilities connected to the Tandem Switch that Sprint provides to its end users.
Tandem Switching. 2.1 The Tandem Switching Capability Network Element is defined as:
(1) an unbundled Network Element in Ameritech's Class 4 non-TOPS digital Tandem Switches, which includes Interconnection with the trunk at the Tandem Distribution Frame (TDF) and the Tandem Switch trunk ports;
(2) the basic switching function of creating a temporary transmission path that connects CLEC's trunks to the trunks of Ameritech, IXCs, ICOs, CMRS, and other LECs interconnected to the Tandem Switch.
2.2 Interconnecting trunk types which can be switched include FGB, FGC, FGD and Type II. Signaling support includes Rotary, MF, and SS7 and any signaling conversions between these signaling formats.
2.3 Variations in Tandem Switching equipment used to provide service in specific locations may cause differences in the operation of certain features.
2.4 The unbundled Tandem Switching Network Element will provide to CLEC all available basic Tandem Switching functions and basic capabilities that are centralized in the Tandem Switch (and not in End Office Switches), including the following functions Ameritech makes available to its Customers:
1. Routing of calls from an inbound trunk to an outbound trunk based on destination digits.
2. Routing of Equal Access or Operator Service calls from an inbound trunk to an outbound trunk based on the CIC forwarded by the inbound trunk.
2.5 Translations, screening, blocking, and route indexing are provided if technically feasible under the standard switching translations and screening in use in that switch. A request for translations, screening, blocking, route indexing other than what is available (i.e., features that the switch is capable of providing) in that switch will be provided where technically feasible as a Bona Fide Request. Ameritech will provide these features if technically feasible and upon agreement by CLEC to pay the applicable recurring and nonrecurring costs of developing, installing, providing and maintaining the capability. Variations in the Tandem Switching equipment or translation and screening used to provide service in specific locations may cause differences in the operation of the element.
(13) Schedule 9.2.4 has been replaced with the following language:
Tandem Switching. The Tandem Switching rate element is charged on every minute of use that is switched by Sprint’s Tandem Switch.
