Voice Grade Unbundled Copper Sub-Loop Unbundled Sub-Loop Distribution – Intrabuilding Network Cable (aka riser cable)
Unbundled Subloop Distribution (USLD) 2.8.2.1 The USLD facility is a dedicated transmission facility that BellSouth provides from an End User’s point of demarcation to a BellSouth cross-connect device. The BellSouth cross-connect device may be located within a remote terminal (RT) or a stand-alone cross-box in the field or in the equipment room of a building. The USLD media is a copper twisted pair that can be provisioned as a 2-wire or 4-wire facility. BellSouth will make available the following subloop distribution offerings where facilities exist: USLD – Voice Grade (USLD-VG) Unbundled Copper Subloop (UCSL) USLD – Intrabuilding Network Cable (USLD-INC (aka riser cable))
WHOIS query RTT Refers to the RTT of the sequence of packets from the start of the TCP connection to its end, including the reception of the WHOIS response. If the RTT is 5-‐times or more the corresponding SLR, the RTT will be considered undefined.
Unbundled Voice Loops (UVLs) 2.2.1 BellSouth shall make available the following UVLs:
Distribution of UDP and TCP queries DNS probes will send UDP or TCP “DNS test” approximating the distribution of these queries.
Unbundled Voice Xxxx - XX0 (XXX-XX0). Loops are 2-wire loop start circuits, will be non-designed, and will not have remote access test points. OC will be offered as a chargeable option on XX0 Xxxxx when reuse of existing facilities has been requested by NewPhone, however, OC is always required on UCLs that involve the reuse of facilities that are currently providing service. NewPhone may also order OC-TS when a specified conversion time is requested. OC-TS is a chargeable option for any coordinated order and is billed in addition to the OC charge. An Engineering Information (EI) document can be ordered as a chargeable option. The EI document provides Loop Make-Up information which is similar to the information normally provided in a Design Layout Record (DLR). Upon issuance of a non-coordinated order in the service order system, XX0 Xxxxx will be activated on the due date in the same manner and time frames that BellSouth normally activates POTS-type Loops for its customers.
Unbundled Sub-Loop Concentration System (USLC 2.9.1 Where facilities permit and where necessary to comply with an effective Commission order, BellSouth will provide <<customer_name>> with the ability to concentrate its sub-loops onto multiple DS1s back to the BellSouth Central Office. The DS1s will then be terminated into <<customer_name>>’s collocation space. TR-008 and TR303 interface standards are available.
How to Update Your Records You agree to promptly update your registration records if your e-mail address or other information changes. You may update your records, such as your e-mail address, by using the Profile page.
Unbundled Voice Loop – SL2 (UVL-SL2 Loops may be 2-wire or 4-wire circuits, shall have remote access test points, and will be designed with a DLR provided to NewPhone. SL2 circuits can be provisioned with loop start, ground start or reverse battery signaling. OC is provided as a standard feature on XX0 Xxxxx. The OC feature will allow NewPhone to coordinate the installation of the Loop with the disconnect of an existing customer’s service and/or number portability service. In these cases, BellSouth will perform the order conversion with standard order coordination at its discretion during normal work hours.
RDDS query RTT Refers to the collective of “WHOIS query RTT” and “Web-‐based-‐ WHOIS query RTT”.
