Loop Provisioning Involving Integrated Digital Loop Carriers 2.6.1 Where Xxxx has requested an Unbundled Loop and BellSouth uses IDLC systems to provide the local service to the End User and BellSouth has a suitable alternate facility available, BellSouth will make such alternative facilities available to Xxxx. If a suitable alternative facility is not available, then to the extent it is technically feasible, BellSouth will implement one of the following alternative arrangements for Xxxx (e.g. hairpinning):
1. Roll the circuit(s) from the IDLC to any spare copper that exists to the customer premises.
2. Roll the circuit(s) from the IDLC to an existing DLC that is not integrated.
3. If capacity exists, provide "side-door" porting through the switch.
4. If capacity exists, provide "Digital Access Cross Connect System (DACS)- door" porting (if the IDLC routes through a DACS prior to integration into the switch).
2.6.2 Arrangements 3 and 4 above require the use of a designed circuit. Therefore, non- designed Loops such as the SL1 voice grade and UCL-ND may not be ordered in these cases.
2.6.3 If no alternate facility is available, and upon request from Xxxx, and if agreed to by both Parties, BellSouth may utilize its Special Construction (SC) process to determine the additional costs required to provision facilities. Xxxx will then have the option of paying the one-time SC rates to place the Loop.
Unbundled Digital Loops 2.3.1 BellSouth will offer Unbundled Digital Loops (UDL). UDLs are service specific, will be designed, will be provisioned with test points (where appropriate), and will come standard with OC and a DLR. The various UDLs are intended to support a specific digital transmission scheme or service.
2.3.2 BellSouth shall make available the following UDLs, subject to restrictions set forth herein:
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.
Unbundled Sub-Loop Feeder 2.8.4.1 Unbundled Sub-Loop Feeder (USLF) provides connectivity between BellSouth's central office and cross-box (or other access point) that serves an end user location.
2.8.4.2 USLF utilized for voice traffic can be configured as 2-wire voice (USLF-2W/V) or 4-wire voice (USLF-4W/V).
2.8.4.3 USLF utilized for digital traffic can be configured as 2-wire ISDN (USLF-2W/I); 2-wire Copper (USLF-2W/C); 4-wire Copper (USLF-4W/C); 4-wire DS0 level loop (USLF-4W/D0); or 4-wire DS1 and ISDN (USLF-4W/DI).
2.8.4.4 USLF will provide access to both the equipment and the features in the BellSouth central office and BellSouth cross box necessary to provide a 2W or 4W communications pathway from the BellSouth central office to the BellSouth cross- box. This element will allow for the connection of Lightyear’s loop distribution elements onto BellSouth's feeder system.
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.
Hot Weather Guidelines For the purposes of site based discussions regarding the need to plan and perform work during expected periods of hot weather, the following issues shall be considered in conjunction with proper consideration of Occupational Health and Safety issues.
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.
DNS name server availability Refers to the ability of a public-‐DNS registered “IP address” of a particular name server listed as authoritative for a domain name, to answer DNS queries from an Internet user. All the public DNS-‐registered “IP address” of all name servers of the domain name being monitored shall be tested individually. If 51% or more of the DNS testing probes get undefined/unanswered results from “DNS tests” to a name server “IP address” during a given time, the name server “IP address” will be considered unavailable.
CLEC OUTAGE For a problem limited to one CLEC (or a building with multiple CLECs), BellSouth has several options available for restoring service quickly. For those CLECs that have agreements with other CLECs, BellSouth can immediately start directing traffic to a provisional CLEC for completion. This alternative is dependent upon BellSouth having concurrence from the affected CLECs. Whether or not the affected CLECs have requested a traffic transfer to another CLEC will not impact BellSouth's resolve to re-establish traffic to the original destination as quickly as possible.
