Telephone Systems. Provide a voice telephone distribution system to
each berth on piers and at drydocks unless specifically instructed otherwise. Provision
should be made for the telephone cable to be terminated in a telecommunications outlet
assembly adjacent to each berth. Provide a Main Distribution Frame (MDF) at the
shore end of the pier for the cross-connect devices. The assembly must include
connectors mounted to the exterior of the enclosure. These connectors will be
connected to the shore end of the ship-to-shore telephone cable. Commercial "dial
tone" services and the telephone switching system is the responsibility of the Station's
Ships Demand. APPENDIX C identifies the number of telephone pair
shore lines required by each ship type. Cable sizes include the ship requirement, the
appropriate embarked-staff requirement, and an allowance for spare pairs. Cable sizes
have been rounded up to the next larger standard telephone cable. The pier telephone
distribution cable system should be designed using the pier's berthing plan. Provide
cable sizes based upon the worst case at each berth. Berths designed for nested ships
should be provided with the total number of cables indicated for all ships in the nest.
Other Demand. Provide telephone service to security checkpoints and
watchstand stations. These requirements may occur at the head and end of the pier,
and at intermediate points along the pier. Coordinate with the Activity's security
Coin-Operated Telephones. When required, provide an independent
conduit system to serve a vendor installed telephone cable which serves shipboard
coin-operated telephones. Unless instructed otherwise, provide a conduit system at the
head of the pier to support coin-operated telephones ashore (also to be vendor
Location and Arrangement of Pier Telephone Distribution System.
Each berth should be served by an independent run of conduit. The
telecommunications outlet assembly must be an independent, freestanding structure.
Outlet assemblies must be designed to prevent damage by ships lines and by traffic on
Other Telecommunications Systems. The need for the systems
described below should be evaluated on a site-by-site basis. Provide these systems as
directed by the Activity and the cognizant NAVFAC EFD/EFA OR USACE DISTRICT.
Dedicated Communication Circuits. Provide one 50.8 mm (2-in)
conduit from the manhole or cross-connect cabinet at the head of the pier to each
