Unbundled Channelization (Multiplexing) 5.7.1 To the extent NewPhone is purchasing DS1 or DS3 or STS-1 Dedicated Transport pursuant to this Agreement, Unbundled Channelization (UC) provides the optional multiplexing capability that will allow a DS1 (1.544 Mbps) or DS3 (44.736 Mbps) or STS-1 (51.84 Mbps) Network Elements to be multiplexed or channelized at a BellSouth central office. Channelization can be accomplished through the use of a multiplexer or a digital cross-connect system at the discretion of BellSouth. Once UC has been installed, NewPhone may request channel activation on a channelized facility and BellSouth shall connect the requested facilities via COCIs. The COCI must be compatible with the lower capacity facility and ordered with the lower capacity facility. This service is available as defined in NECA 4. 5.7.2 BellSouth shall make available the following channelization systems and interfaces: 5.7.2.1 DS1 Channelization System: channelizes a DS1 signal into a maximum of twenty- four (24)
Voice Grade Unbundled Copper Sub-Loop Unbundled Sub-Loop Distribution – Intrabuilding Network Cable (aka riser cable)
Unbundled Network Element Combinations 5.1. Unbundled Network Element Combinations shall include: 1) Enhanced Extended Links (EELs); 2) UNE Loops/Special Access Combinations; 3) Loop/Port Combinations; and 4)
Unbundled Copper Sub-Loop (UCSL) is a copper facility of any length provided from the cross-box in the field up to and including the end-user’s point of demarcation. If available, this facility will not have any intervening equipment such as load coils between the end-user and the cross-box.
Unbundled Sub-Loop Distribution Voice Grade (USLD-VG) is a copper sub- loop facility from the cross-box in the field up to and including the point of demarcation at the End User’s premises and may have load coils.
Access Toll Connecting Trunk Group Architecture 9.2.1 If CSTC chooses to subtend a Verizon access Tandem, CSTC’s NPA/NXX must be assigned by CSTC to subtend the same Verizon access Tandem that a Verizon NPA/NXX serving the same Rate Center Area subtends as identified in the LERG. 9.2.2 CSTC shall establish Access Toll Connecting Trunks pursuant to applicable access Tariffs by which it will provide Switched Exchange Access Services to Interexchange Carriers to enable such Interexchange Carriers to originate and terminate traffic to and from CSTC’s Customers. 9.2.3 The Access Toll Connecting Trunks shall be two-way trunks. Such trunks shall connect the End Office CSTC utilizes to provide Telephone Exchange Service and Switched Exchange Access to its Customers in a given LATA to the access Tandem(s) Verizon utilizes to provide Exchange Access in such LATA. 9.2.4 Access Toll Connecting Trunks shall be used solely for the transmission and routing of Exchange Access to allow CSTC’s Customers to connect to or be connected to the interexchange trunks of any Interexchange Carrier which is connected to a Verizon access Tandem.
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.
Unbundled Voice Loops (UVLs) 2.2.1 BellSouth shall make available the following UVLs:
Unbundled Copper Loops (UCL) 2.4.1 BellSouth shall make available Unbundled Copper Loops (UCLs). The UCL is a copper twisted pair Loop that is unencumbered by any intervening equipment (e.g., filters, load coils, range extenders, digital loop carrier, or repeaters) and is not intended to support any particular telecommunications service. The UCL will be offered in two types – Designed and Non-Designed.
Unbundled Copper Loop – Non-Designed (UCL-ND 2.4.3.1 The UCL–ND is provisioned as a dedicated 2-wire metallic transmission facility from BellSouth’s Main Distribution Frame to a customer’s premises (including the NID). The UCL-ND will be a “dry copper” facility in that it will not have any intervening equipment such as load coils, repeaters, or digital access main lines (“DAMLs”), and may have up to 6,000 feet of bridged tap between the end user’s premises and the serving wire center. The UCL-ND typically will be 1300 Ohms resistance and in most cases will not exceed 18,000 feet in length, although the UCL-ND will not have a specific length limitation. For loops less than 18,000 feet and with less than 1300 Ohms resistance, the loop will provide a voice grade transmission channel suitable for loop start signaling and the transport of analog voice grade signals. The UCL-ND will not be designed and will not be provisioned with either a DLR or a test point. 2.4.3.2 The UCL-ND facilities may be mechanically assigned using BellSouth’s assignment systems. Therefore, the Loop Make Up process is not required to order and provision the UCL-ND. However, Lightyear can request Loop Make Up for which additional charges would apply. 2.4.3.3 At an additional charge, BellSouth also will make available Loop Testing so that Lightyear may request further testing on the UCL-ND. Rates for Loop Testing are as set forth in Exhibit B of this Attachment. 2.4.3.4 UCL-ND loops are not intended to support any particular service and may be utilized by Lightyear to provide a wide-range of telecommunications services so long as those services do not adversely affect BellSouth’s network. The UCL-ND will include a Network Interface Device (NID) at the customer’s location for the purpose of connecting the loop to the customer’s inside wire. 2.4.3.5 Order Coordination (OC) will be provided as a chargeable option and may be utilized when the UCL-ND provisioning is associated with the reuse of BellSouth facilities. Order Coordination -Time Specific (OC-TS) does not apply to this product. 2.4.3.6 Lightyear may use BellSouth’s Unbundled Loop Modification (ULM) offering to remove bridge tap and/or load coils from any loop within the BellSouth network. Therefore, some loops that would not qualify as UCL-ND could be transformed into loops that do qualify, using the ULM process.
