32、ocal service restoral objectives and provides them to the ASC upon request. Performs cooperative maintenance testing with the ASC when requested. Designates a Data Network Control Center for the X.75 Gateway Service furnished to an ASC. 3 Installation of X.75 Gateway Installation, as used in this do

33、cument, means that portion of the total provisioning process which starts when an order is received by the Data Network Control Center and includes new connect, change, and disconnect activities. 6 3.1 Pre-Service Testing of X.75 Gateway The ASP DNCC should ensure the following before contacting the

34、 ASC to perform cooperative acceptance tests: That pre-service tests have been performed and the service is ready for acceptance tests. That all pre-service test results have been recorded. That the ASP portion of the X.75 Gateway Service has been installed correctly. ASC personnel or their designat

35、e may be invited to participate in the pre-service testing activity. 3.2 Cooperative Acceptance Testing Upon completion of the pre-service tests, the ASP DNCC shall contact the ASC and advise that the ASP portion of the X.75 Gateway service is ready for acceptance testing. The ASCs DNCC shall coordi

36、nate all normal and additional acceptance testing. Test equipment compatibility should be verified at this time. The ASC is not obligated to accept the service prior to the due date. The ASC is also not obligated to accept the service without successful acceptance test completion. Basic acceptance t

37、est requirements may be found in the X.75 Gateway Service, Technical References tariffs or bilateral agreements. 3.3 Completion Reporting Upon acceptance of the ASP access service by the ASC, the ASP DNCC shall record the name of the ASC representative and the date the service is accepted. 3.4 Disco

38、nnection of Service Disconnect procedures shall be in accordance with ASP and ASC developed practices or as stated in the applicable X.75 Gateway tariff, or bilateral agreements. 3.5 Rearrangements A rearrangement as described in this document is a coordinated activity initiated by either the ASP or

39、 the ASC which will usually be transparent to the end users and will not change the operation of virtual calls. In the rearrangement process, circuit releases, rearrangement timing, and acceptance testing shall be negotiated on an individual case basis (ICB). 3.6 Change Orders Change orders cover an

40、y changes in the design or operation of an existing X.75 Gateway Service administered through the ICSC or equivalent center procedures. 3.7 Routine Maintenance Activity It is the recommendation of the NGIIF that all routine maintenance and scheduled work activities be performed during hours of minim

41、um traffic (e.g., during an 11:00 pm to 5:00 am “maintenance window“) so that any inadvertent failure impacts the least number of customers. 7 At a minimum, high risk, potentially service affecting maintenance and growth procedures should be scheduled during weekend and off-hours. The overall method

42、s, procedures and scheduling of these work activities should be reviewed by a second tier maintenance organization. The activities that may affect other network service providers must be coordinated, which includes both intra- and inter-carrier networks. (See NGIIF Reference Document, Section III, I

43、nstallation and Maintenance - SS7). Non Scheduled Work Activity. If customer service is being impacted, the minimum work activity will occur to restore the system to a stable performance state. Complete system recovery activity will be scheduled for the next maintenance window period. 4 Maintenance

44、The ASC is responsible for performing all necessary tests in its service to determine the nature of the trouble detected or reported by its customer or an ASP. If the trouble is sectionalized to an ASP provided service, the ASC shall report the trouble to the appropriate ASP DNCC. Likewise the ASP i

45、s responsible for performing all necessary tests to determine the nature of the trouble detected, or reported by its customers. If the trouble is sectionalized to an ASC, the ASP will report the trouble to the appropriate ASCs point of contact. The ASP shall accept trouble reports from the ASC, sect

46、ionalized to the ASPs network. Likewise, the ASC shall accept from the ASP trouble reports sectionalized to the ASCs network. The ASP and ASC shall test cooperatively and/or independently, as required to sectionalize the trouble. 4.1 Trouble Reporting The following is the type of information which s

47、hould be exchanged at the time of the trouble referral. Circuit identification number. Date and time of trouble referral. Nature of the trouble and any other information that may be of assistance to the ASP Control Office. The name or initials and the telephone number of the person referring the tro

48、uble. Trouble ticket number(s) or equivalent and the name or initials of the person accepting the trouble. 4.2 Sectionalization and Repair Trouble sectionalization may involve cooperative testing by the ASC and ASP(s) which shall be provided when requested. The carrier requesting cooperative testing

49、 assumes coordination responsibility. Communication may also be necessary on services that involve an ASC, its designated agent, and an ASP. In these situations the cooperation of all three organizations may be necessary to expedite trouble clearance. When it is necessary for communication between the ASC and ASP, it is required that this contact may be made through the designated agent. The ASC may not rearrange, move, disconnect, remove or attempt to repair any equipment or facilities provided by t
