Wire routing
The routing of all wires for the SL-1 must be specified as part of the plan.
To plan wire routing, establish the start and end point of each cable relative
to the location of telephones in the office. Remember that each modular
jack (8-pin or 6-pin, for example) must be within 8 feet.
(2.4 m) of the telephones.
At this point the construction of the office must be investigated to determine
the best wiring routes. Consider the following information when
performing this task
Floors
Telephone wire travels along floors in one of two ways:
- Out in the open: In some cases wires are tacked to the surface of walls
and other physical structures. For the safety of employees, wire should
never be stretched across the top of floor. Run the wires along
baseboards, ceiling mouldings, or door and window casings.
- Concealed: In other cases wires are run inside a floor conduit. The
conduits can travel between utility closets and jack locations. In some
cases the floor conduits connect to a conduit passing through walls or
ceilings. In all cases the conduit must be used exclusively for
telephone cables. The use of under-carpet cables is not recommended.
Ceilings
The National Electrical Code and local building codes specify what types of
telephone wire may be run in each type of ceiling. Local building codes
take precedence.
Walls
Wiring that needs to be run horizontally cannot be blind fed through walls.
Cables that need to be run vertically should, when possible, run inside a
wall, pole, or similar facility for vertical wire drops.
Between floors
Telephone utility closets should be located as closely to one another as
possible. In many cases, contractors are hired to install the conduit. Local
coding laws will specify whether a licensed contractor is required.
