25、 9.1.5 55-Octet Stress Test Pattern 26 5 1 General This document outlines Access Service Customer (ASC) and Access Service Providers (ASP) responsibilities for Installation, Testing and Maintenance of Facilities as established by the Network Interconnection Interoperability Forum (NGIIF). It is inte

26、nded to be a living document to aid operations work forces. It does not replace nor supersede Tariffs, Contracts or any other legally binding documents. The installation and maintenance of SS7, Specials and Feature Group A, Feature Groups B, C, and D are included in separate sections of the NGIIF Re

27、ference Document. In addition, Network Management Guidelines and Testline Guidelines are included as well. In addition to other operational and technical agreements made at the Network Interconnection Interoperability Forum, this document is being issued to incorporate the following changes. This do

28、cument is a new addition to the Network Interconnection Interoperability Forum library of documentation, exclusively for Facilities. The ASCs are communications common carriers authorized by the appropriate regulatory bodies, the Federal Communications Commission (FCC) to provide interLATA, intersta

29、te communications and/or by State or Provincial Public Utilities Commissions (PUCs) to provide interLATA, intrastate or intraLATA communications to their end users. The ASCs may request Access Service Providers (ASP) to provide various facilities as addressed in this document to be used as part of t

30、he ASCs services. The fundamental principles governing the relations between the ASPs and the ASCs are: The ASCs have responsibility for the end-to-end service of their end users. The ASPs will provide facility connectivity to the ASCs as set forth by their Access Service Tariffs and will show no di

31、scrimination between different ASCs. 2 Responsibilities This section outlines the responsibilities for Access Service Customers (ASC) and Access Service Providers (ASP). 2.1 Access Service Customer (ASC) The ASC has the overall installation and maintenance responsibility for the total facility to it

32、s end user. The ASC is responsible for the overall coordination of installation and testing of its facilities. The ASC is responsible for negotiation of control to another entity. The following are the responsibilities of the ASCs: Provides trained personnel. Advises the ASP when there is an ASC net

33、work failure that may affect the ASP services. Provides a contact number for trouble reporting that is readily accessible 24 hours a day, 7 days a week. Maintains complete and accurate installation and repair records. Provides ASP personnel access to the Point of Termination (POT) when required. Pro

34、vides access to testlines where appropriate. Provides billing authorization to the ASP for any additional labor requested. 6 Ensures the test equipment used is compatible with the ASPs test equipment. Cooperates with the ASP ensuring that facilities are installed in accordance with the service reque

35、sts. Notifies the ASP of any changes affecting the service requested, including the service due date. Assumes control functions for maintenance of its facilities. Consulting with the ASP before making any changes that would affect service except under emergency conditions. Accepts trouble reports fr

36、om their end users. Accepts trouble reports from the ASPs. Sectionalizes and clears the trouble in its own network. Test cooperatively and with the ASP to further isolate and clear the trouble. Keeps their end user advised of the status of all trouble report(s). Performs cooperative analysis to dete

37、rmine if a trouble pattern exists. Refers troubles to the ASP using the trouble reporting procedures. Dispatches its own maintenance forces. Performs verification test to ensure that trouble has been cleared. Performs scheduled testing and other maintenance services when requested. Participates coop

38、eratively with the ASP to further isolate and clear the trouble when trouble exists and cannot be sectionalized. 2.2 Access Service Provider (ASP) The ASP is responsible for ensuring that the facilities furnished to an ASC are installed and function properly. In addition, the ASP should work coopera

39、tively and with the ASC in the testing of the facilities it provides. The following are the responsibilities of the ASPs: Provides trained personnel. Advise the ASC when there is a potential service affecting ASP network failure. Provides a contact number for trouble reporting that is readily access

40、ible 24 hours a day, 7 days a week. Maintain complete and accurate installation and repair records. Consults with the ASC before making any changes that could affect service except under emergency conditions. (See Network Modification section). Provides access to testlines where appropriate. Assumes

41、 control functions for the installation of the facilities. Coordinates with the ASC ensuring that facilities are installed in accordance with the service requests. Notifies the ASC of any changes affecting the service requested, including the service due date. Accepts trouble reports from the ASCs.

42、7 Sectionalizes and clears the trouble in its own network. Test cooperatively with the ASC to identify and clear a trouble when the trouble has been sectionalized to an ASC network. Performs cooperative analysis to determine if a trouble pattern exists. Refers troubles to the ASC using the trouble r

43、eporting procedures. Dispatches its own maintenance forces. Performs verification tests to ensure that trouble has been cleared. Provide status reports to the ASC regarding installation and repair activity. Perform scheduled testing and other maintenance services when requested. Participates coopera

44、tively with the ASC to further isolate and clear the trouble when trouble exists. Provides ASC personnel access to the Point of Termination (POT) when required. Ensures that test equipment used is compatible with the ASCs test equipment. 3 Network Service Center (NSC) The NSC, or other regionally de

45、signated centers, will be the contact point for non-circuit specific trouble reports from the ASC. The ASP will provide the ASC with a contact number, escalation and guidelines for reporting of non-circuit specific troubles. The NSC will provide status and feedback to the Reporting ASC, when request

46、ed. 4 Network Modification Notification A Network Modification is any type of planned equipment, software, trunk or facility activity that has the potential to significantly affect interconnected networks (e.g. rearrangement of existing network elements, switch homing arranges, SS7 rehoming) The NGI

47、IF has developed the following guidelines outlining the medium by which internetwork affecting maintenance activity notification will be provided to the interconnected company and the time frame prior to the planned activity: Notification when possible should be made at least 5 working days prior to

48、 the planned change activity. Notification should be made in the form of: E-Mail (recommended where available), FAX or, Telephone call. Notification should be provided to the affected companys appropriate notification center. Contact information is included in the NGIIF Service Provider Contact Dire

49、ctory. An example of a notification form is located in the NM Section, Part VI, of the NGIIF Reference Document. When network modifications are scheduled that could significantly affect traffic between directly interconnected networks, it is recommended that the affected ASPs and ASCs will notify each other, prior to the event. 8 The following information should be exchanged at the time of notification: Originator, (company name/contact number) Affected Network Element Date and Tim
