Different gauge drop wires exist. Many DPs for which the Phone Mechanic is Removing the pair from DP termination and twisting the UG cable pair to Drop wire directly. Non feasible areas exist. High telephone density exists One subscriber is a custom

    8. For Acceptance Testing of External plant the following should be physically inspected and tested Cabinets and pillars. b. Pole- Mounted DP c. Internal DP d. Service line. e. Indoor House Wiring g. Electric Parameters of Line h. Dial of subscriber’s instrument
