  3. Unbundled Voice Loops (UVL) Definition The main intent of the UVL is to provision analog voice grade services. UVL will be provisioned, maintained, and repaired in a manner that supports voice grade services such as basic POTS service. • The UVL is a dedicated analog transmission facility from BellSouth’s main distribution frame (MDF) to an end user’s premises. This facility allows an end user to send and receive normal voice telecommunications traffic when it is connected to a dial-tone-providing switch. This facility will include a Network Interface Device (NID) at the customer’s location for the purpose of connecting the loop to the customer’s inside wiring. • UVLs may be provisioned using any type of facility that will support voice grade services. This may include loaded copper, non-loaded copper, digital loop carrier systems, fiber/copper combination (hybrid loop) or a combination of any of these facilities. Issue Date 6/30/04

  4. Unbundled Voice Loops (UVL) Definition(continued) • There are two levels of UVL service: Service Level 1 (SL1) – Non-designed; Service Level 2 (SL2) – Designed. • Technical Specifications for this loop can be found in the TR73600 guide posted on the BellSouth Interconnection website. Refer to page 10 of this document for the website URL. Issue Date 6/30/04

  5. Unbundled Digital Loops (UDL) Definition The main intent of the UDL is to provision data services. UDL will be provisioned, maintained, and repaired in a manner that supports digital services. • The UDL is a dedicated digital transmission facility from BellSouth’s Main Distribution Frame (MDF) to a customer’s premises. • This facility allows the end user to send and receive traffic utilizing technologies such as: • Integrated Services Digital Network (ISDN) (2-wire/4-wire) • Advanced Services (xDSL) that use the following: • Asymmetrical Digital Subscriber Line (ADSL) copper loop 18k ft (2-wire/4-wire) • High Density Subscriber Loop/Line (HDSL) copper 12k ft (2-wire/4-wire) Issue Date 6/30/04

  6. Unbundled Digital Loops (UDL) Definition (continued) • DS0 (4-wire) • 19K • 56K • 64K Issue Date 6/30/04

  7. Unbundled Digital Loops (UDL) Definition (continued) • High capacity Loops • DS1 (4 Wire) Digital loops may be provided via metallic facilities, Digital Loop Carrier (DLC), or both. The insertion loss of the metallic facility measured at 28khz between 135 ohm terminations will be less than 40 db. These facilities are provided with no DLC, load coils or repeaters. Bit Rate Performance is dependent upon the Customer Premises Equipment (CPE). For that reason, BellSouth does not guarantee a particular bit rate associated with these loops. • Technical Specifications for this loop can be found in the TR73600 guide posted on the BellSouth Interconnection website. Refer to page 10 of this document for the website URL. Issue Date 6/30/04

  8. Unbundled Copper Loops/Designed (UCL-D) Definition • The UCL-D is a dedicated metallic transmission facility from BellSouth’s Main Distribution Frame (MDF) to a customer’s premises. • A UCL-D is commonly referred to as a “dry copper” loop, because it does not have any intervening equipment such as load coils and repeaters between the end user premises and the Serving Wire Center (SWC). • It is a Resistance Design (RD) copper loop of 1300 ohms or less with a total length of 18k ft or less. Up to 6k ft of bridge tap may be included on the loop facility. • BellSouth offers 2 Wire or 4 Wire UCL. Issue Date 6/30/04

  9. Unbundled Copper Loops/Designed (UCL-D) Definition (continued) • The UCL-D Loop is a designed facility and is provisioned with a test point. BellSouth will provide a Design Layout Record (DLR). • These loops are not intended to support any particular type of service and may be utilized by the D/CLEC to provide a wide-range of telecommunications services. BellSouth does not guarantee a particular bit rate with this particular loop. • Technical Specifications for this loop can be found in the TR73600 guide posted on the BellSouth Interconnection website. Refer to page 10 of this document for the website URL. Issue Date 6/30/04

  10. Unbundled Copper Loops/Non-Designed (UCL-ND) Definition • The UCL-ND is provisioned as a dedicated two-wire metallic transmission facility from BellSouth’s Main Distribution Frame to the end user’s premise including the Network Interface Device (NID). • A UCL-ND is commonly referred to as a “dry copper” loop, because it does not have any intervening equipment such as load coils, repeaters or Digital Access Main Lines (DAMLs) between the end user premises and the Serving Wire Center (SWC). • A UCL-ND is typically 1300 ohms resistance and in most cases will not exceed 18k ft in length, although there is no length limitations. Issue Date 6/30/04

  11. Unbundled Copper Loops/Non-Designed (UCL-ND) Definition (continued) • The UCL-ND may contain bridge taps of up to 6,000 ft between the end user’s location and the Service Wire Center (SWC). • THE UCL-ND is a 2 Wire non-designed facility. • These loops are not intended to support any particular type of service and may be utilized by the D/CLEC to provide a wide-range of telecommunications services. BellSouth does not guarantee a particular bit rate with this particular loop. • Technical Specifications for this loop can be found in the TR73600 guide posted on the BellSouth Interconnection website. Refer to page 10 of this document for the website URL. Issue Date 6/30/04
