Loop Provisioning Involving Integrated Digital Loop Carriers 2.6.1 Where EveryCall has requested an Unbundled Loop and BellSouth uses Integrated Digital Loop Carrier (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 EveryCall. 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 EveryCall (e.g. hairpinning):
Network Access Control The VISION Web Site and the Distribution Support Services Web Site (the “DST Web Sites”) are protected through multiple levels of network controls. The first defense is a border router which exists at the boundary between the DST Web Sites and the Internet Service Provider. The border router provides basic protections including anti-spoofing controls. Next is a highly available pair of stateful firewalls that allow only HTTPS traffic destined to the DST Web Sites. The third network control is a highly available pair of load balancers that terminate the HTTPS connections and then forward the traffic on to one of several available web servers. In addition, a second highly available pair of stateful firewalls enforce network controls between the web servers and any back-end application servers. No Internet traffic is allowed directly to the back-end application servers. The DST Web Sites equipment is located and administered at DST’s Winchester data center. Changes to the systems residing on this computer are submitted through the DST change control process. All services and functions within the DST Web Sites are deactivated with the exception of services and functions which support the transfer of files. All ports on the DST Web Sites are disabled, except those ports required to transfer files. All “listeners,” other than listeners required for inbound connections from the load balancers, are deactivated. Directory structures are “hidden” from the user. Services which provide directory information are also deactivated.
Two-Way Interconnection Trunks 2.4.1 Where the Parties have agreed to use Two-Way Interconnection Trunks for the exchange of traffic between Verizon and ICG, ICG shall order from Verizon, and Verizon shall provide, the Two-Way Interconnection Trunks, and the Entrance Facility on which such Trunks will ride, and transport and multiplexing, in accordance with the rates, terms and conditions set forth in this Agreement and Verizon’s applicable Tariffs.
Signaling protocol The Parties will interconnect their networks using SS7 signaling where Technically Feasible and available as defined in GR 905 Telcordia Standards including ISDN User Part (ISUP) for trunk signaling and TCAP for CCS-based features in the Interconnection of their networks. All Network Operations Forum (NOF) adopted standards shall be adhered to. Where available, CenturyLink signaling services to link its Signaling Transfer Points (STPs) for CLEC switches which connect to CenturyLink’s STPs via “A” links or for CLEC’s STPs to connect to CenturyLink’s STPs via “D” links which are dedicated to the transport of signaling for local Interconnection, may be ordered from the CenturyLink Tariff.
Traffic Measurement and Billing over Interconnection Trunks 6.1 For billing purposes, each Party shall pass Calling Party Number (CPN) information on at least ninety-five percent (95%) of calls carried over the Interconnection Trunks.
Network Interconnection Architecture Each Party will plan, design, construct and maintain the facilities within their respective systems as are necessary and proper for the provision of traffic covered by this Agreement. These facilities include but are not limited to, a sufficient number of trunks to the point of interconnection with the tandem company, and sufficient interoffice and interexchange facilities and trunks between its own central offices to adequately handle traffic between all central offices within the service areas at P.01 grade of service or better. The provisioning and engineering of such services and facilities will comply with generally accepted industry methods and practices, and will observe the rules and regulations of the lawfully established tariffs applicable to the services provided.
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.
One-Way Interconnection Trunks 2.3.1 Where the Parties use One-Way Interconnection Trunks for the delivery of traffic from CBB to Verizon, CBB, at CBB’s own expense, shall:
Access Toll Connecting Trunk Group Architecture 9.2.1 If CBB chooses to subtend a Verizon access Tandem, CBB’s NPA/NXX must be assigned by CBB to subtend the same Verizon access Tandem that a Verizon NPA/NXX serving the same Rate Center Area subtends as identified in the LERG.
Sub-loop Elements 2.8.1 Where facilities permit, BellSouth shall offer access to its Unbundled Sub-Loop (USL) elements as specified herein.
