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.
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.
Extended Local Calling Scope Arrangement An arrangement that provides a Customer a local calling scope (Extended Area Service, “EAS”), outside of the Customer’s basic exchange serving area.
Originating Switched Access Detail Usage Data A category 1101XX record as defined in the EMI Telcordia Practice BR-010-200- 010.
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.
Wire Unbundled DS1 Digital Loop This is a designed 4-wire Loop that is provisioned according to industry standards for DS1 or Primary Rate ISDN services and will come standard with a test point, OC, and a DLR. A DS1 Loop may be provisioned over a variety of loop transmission technologies including copper, HDSL-based technology or fiber optic transport systems. It will include a 4-Wire DS1 Network Interface at the End User’s location.
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.
Switching All of the negotiated rates, terms and conditions set forth in this Section pertain to the provision of local and tandem switching.
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.
Line Outage Costs Notwithstanding anything in the NYISO OATT to the contrary, the Connecting Transmission Owner may propose to recover line outage costs associated with the installation of Connecting Transmission Owner’s Attachment Facilities or System Upgrade Facilities or System Deliverability Upgrades on a case-by-case basis.
