12、d fiber cable system ownershould notify the other entity as far in advance as possible forplanned, routine operations.6.4.1.2 Improper cable repair or maintenance proceduresmay damage the sewer or optical fiber system, creating anunsafe situation. Because of this risk, the fiber cable systemowner mu

13、st notify the sewer pipeline operator as to the natureof the intended repair or maintenance and verify whether seweroperator supervision or oversight is required during the repairor maintenance.6.4.2 Extended Duration Access (4 hours+) to Sewer Vaultsby Optical Fiber System OwnerWhen accessing a sew

14、ervault or sewer manhole, the optical fiber cable owner mustprovide the sewer pipeline operator with at least 48 hours priornotice. If re-cabling, replacing the conduit or other extendeddurations repairs are contemplated, the optical fiber systemowner must provide with that notice, written repair pr
