Communication and Activation 4-3
In addition, notify the local underground utilities locating service
concerning the desired pedestal location and cable route.
Typically, notification must occur 2 to 3 days before excavation
activities are scheduled to begin.
After finalizing the pedestal location and cable route, run the
telephone cable between the monitor location and the designated
pedestal location in the following way:
1. Excavate a trench at least 12 inches deep from the designated
telephone service pedestal location to the monitor location.
Consult the local regulations to verify the required trench
depth for the area.
2. Drill a hole in the corbel (structural foundation holding the
manhole cover) of the manhole large enough to accommodate
the diameter of ¾-inch electrical conduit plus an extra ½ inch.
3. Run the telephone cable from the monitor location in the
manhole to the telephone service pedestal location through ¾-
inch electrical conduit. Consider the following parameters and
recommendations when running the cable:
Use four-conductor Belden  cable.
Do not use plumbing conduit or water fittings.
Run the telephone cable through the conduit one section at
a time as you lay the conduit in the trench and connect the
sections of conduit together. When necessary, use fish
tape to feed the telephone cable through the conduit.
Provide enough slack in the cable at the manhole end to
allow removal of the monitor from the manhole during
service activities.
Provide approximately 12 to 15 inches of excess cabling at
the telephone service pedestal.
Create a drip loop for any wires or cables that may be
subject to condensation to prevent moisture from entering
the electrical or telephone boxes.
Extend the conduit through the hole in the corbel of the
manhole at the monitor location.
