24、sioning of services assigned emergency priority, which should always be done before the restoration of services assigned restoration priorities “2“, “3“, “4“ or “5“. Restoration of any service assigned restoration priority “1“ takes precedence over any other service assigned any other provisioning a

25、nd restoration priority. When two or more TSP services are competing for resources, the priority sequence listed below will ensure proper handling of these circuits: Restore TSP services with restoration priority of “1” Provision TSP services with provisioning priority of “E” Restore TSP services wi

26、th restoration priority of 2, 3, 4, and 5 Provision TSP services with provisioning priority of 1, 2, 3, 4, and 5. Using the priority sequence listed above, the following are examples of two TSP services competing for the same resources at the same time. The underlined TSP service has the higher prio

27、rity and should be worked on first: TSP code 2-1 and E-2 both in trouble status 2-1 TSP code 2-1 in trouble and E-2 to be provisioned 2-1 TSP code 2-1 to be provisioned and E-2 in trouble E-2 TSP code 2-1 and E-2 to be provisioned E-2. 3.7 TSP Installation Preemption Where facilities and/or equipmen

28、t are not available to install a service assigned a TSP priority, preemption (interruption of an existing service) of a non-priority or lower priority circuit may be required. User consent is NOT required to preempt any users existing service to provision an NS/EP service assigned a provisioning pri

29、ority level “E“ (Emergency) or to provision an NS/EP service assigned a provisioning priority level “1“ through “5“. 7 3.8 TSP Maintenance Preemption Facilities of message circuits may be used for restoral of services assigned a TSP restoration priority after ensuring that sufficient message circuit

30、s are available for public switched network use. Where facilities and/or equipment are not available to restore a service assigned, a TSP restoration priority preemption (interruption of an active service) may be required. Interruption of a non-priority or lower priority circuit is authorized for th

31、e purpose of restoring the service assigned a TSP restoration priority. 3.8.1 To restore interrupted NS/EP services: User consent is not required to preempt any users existing service to restore any NS/EP service assigned a restoration priority lever from “1“ through “5“. 3.8.2 NS/EP services: If no

32、 suitable spare or non-NS/EP services are available, existing NS/EP services may be preempted to restore NS/EP services with higher priority level assignments. When this is necessary, NS/EP services will be selected for preemption in the inverse order of priority level assignment. Service vendors wh

33、o are preempting services will ensure their best effort to notify the service user of the preempted service and state the reason for, and estimated duration of, the preemption. 4 NXX Code Openings1 NOTE: For information related to NPA-NXX testing refer to ATIS-0300024, Next Generation Interconnectio

34、n Interoperability (NGIIF) Reference Document Part V, Test Line Guidelines. This section outlines the process and procedures for the testing of newly assigned Central Office NXX or NXX-X codes opened for the first time. In addition, this section provides references for the user to ensure that they a

35、re familiar with the obligations associated with obtaining codes and notifying the industry of the pending opening of CO NXX codes. In a Thousands Block Number Pooling environment the first thousands block that is opened in a NPA/NXX will follow the same rules as outlined in all NXX code opening pro

36、cedures. NPA/NXX and NPA/NXX-X are interchangeable in NXX code opening scenarios throughout the NGIIF documentation. In these cases the Code Holder is responsible for the testing. The non-operational aspects contained in this section do not replace or supersede existing industry forum agreements or

37、documents covering NXX or NXX-X Code opening processes. Listed below are specific documentation provided by the Industry Numbering Committee (INC) and NGIIF that provides guidance to Code Administrators, Service Providers and Service Customers when obtaining, activating, and testing NXX or NXX-X cod

47、 points of interconnection in the LATA where the CO Code resides. In addition, the code holder shall immediately assign a number to be utilized for call through testing purposes upon receipt of the CO Code and shall place the test number in the iconectiv LERG Routing Guide when entering the CO Code

48、into the iconectiv LERG Routing Guide. 4.2.3 Facilities Offices attempting to complete a call through test to the new CO Code (NXX or NXX-X) when the facilities are not in place shall contact the code holder and inform them that the routing of calls will not take place until the appropriate facility

49、 orders have been completed. In cases where orders have been placed with LECs for facilities, but have not been implemented, the LEC shall provide the appropriate support to ensure that the orders are complete and appropriate testing has been performed to meet the due date. 4.2.4 Points of Interconnection In cases where points of interconnection in the home NPA have not been identified and/or facilities have not been placed, the code holder (NXX or NXX-X) will accept full responsibility for placing such orders with th
