Common use of Fibers Clause in Contracts

Fibers. MFN shall perform appropriate Scheduled Maintenance on the cable containing the NEXTLINK Fibers in accordance with MFN's then current preventative maintenance procedures as agreed to by NEXTLINK, which shall not substantially deviate from standard industry practice. MFN shall maintain sufficient capability to teleconference with NEXTLINK during an Emergency Unscheduled Maintenance in order to provide regular communication during the repair process. When correcting or repairing cable discontinuity or damage, including but not limited to in the event of Emergency Unscheduled Maintenance, MFN shall use reasonable efforts to repair traffic-affecting discontinuity within four (4) hours after the MFN maintenance employee's arrival at the problem site. In order to accomplish such objective, it is acknowledged that the repairs so effected may be temporary in nature. In such event, within twenty-four (24) hours after completion of any such Emergency Unscheduled Maintenance, MFN shall commence its planning for permanent repair, and thereafter promptly shall notify NEXTLINK of such plans, and shall implement such permanent repair within an appropriate time thereafter. Restoration of open fibers on fiber strands not immediately required for service shall be completed on a mutually agreed-upon schedule. If the fiber is required for immediate service, the repair shall be scheduled for the next available Planned Service Work Period ("PSWP"). In performing repairs, MFN shall comply with the splicing specifications as set forth in Exhibit E. MFN shall provide to NEXTLINK any modifications to these specifications as may be necessary or appropriate in any particular instance for NEXTLINK's approval, which approval shall not be unreasonably withheld. MFN's representatives that are responsible for initial restoration of a cut cable shall carry on their vehicles the typically appropriate equipment that would enable a temporary splice, with the objective of restoring operating capability in as little time as possible. MFN shall maintain and supply an inventory of spare cable in storage facilities supplied and maintained by MFN at strategic locations to facilitate timely restoration.
