Access Toll Connecting Trunk Group Architecture 9.2.1 If WCS chooses to subtend a Verizon access Tandem, WCS’s NPA/NXX must be assigned by WCS 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 WCS 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 WCS’s Customers. 9.2.3 The Access Toll Connecting Trunks shall be two-way trunks. Such trunks shall connect the End Office WCS 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 WCS’s Customers to connect to or be connected to the interexchange trunks of any Interexchange Carrier which is connected to a Verizon access Tandem.
Infrastructure Vulnerability Scanning Supplier will scan its internal environments (e.g., servers, network devices, etc.) related to Deliverables monthly and external environments related to Deliverables weekly. Supplier will have a defined process to address any findings but will ensure that any high-risk vulnerabilities are addressed within 30 days.
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 Global Connection’s loop distribution elements onto BellSouth's feeder system.
Signaling protocol 4.1.3.1 SS7 Signaling is AT&T-21STATE’s preferred method for signaling. Where MF signaling is currently used, the Parties agree to use their best efforts to convert to SS7. If SS7 services are provided by AT&T-21STATE, they will be provided in accordance with the provisions of the applicable access tariffs. 4.1.3.2 Where MF signaling is currently used, the Parties agree to interconnect their networks using MF or dual tone MF (DTMF) signaling, subject to availability at the End Office Switch or Tandem Switch at which Interconnection occurs. The Parties acknowledge that the use of MF signaling may not be optimal. AT&T-21STATE will not be responsible for correcting any undesirable characteristics, service problems or performance problems that are associated with MF/SS7 inter-working or the signaling protocol required for Interconnection with CLEC employing MF signaling.
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 (MDF) 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 Makeup (LMU) process is not required to order and provision the UCL-ND. However, CBX One-Stop can request LMU for which additional charges would apply. 2.4.3.3 For an additional charge, BellSouth also will make available Loop Testing so that CBX One-Stop may request further testing on the UCL-ND. Rates for Loop Testing are as set forth in Exhibit A of this Attachment. 2.4.3.4 UCL-ND Loops are not intended to support any particular service and may be utilized by CBX One-Stop to provide a wide-range of telecommunications services as long as those services do not adversely affect BellSouth’s network. The UCL- ND will include a NID at the customer’s location for the purpose of connecting the Loop to the customer’s inside wire. 2.4.3.5 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. OC-TS does not apply to this product. 2.4.3.6 CBX One-Stop may use BellSouth’s Unbundled Loop Modification (ULM) offering to remove excessive bridged taps and/or load coils from any copper 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.
