7. Connecting Telephone Service
7.1 Safety Precautions
Remember, when working on existing telephone service it is possible to come in contact
with electrical currents. Again, TELUS recommends that installations be carried out by a
trained technician. Work on telephone or any wiring should never be undertaken during
thunder and lightning storms.
To reduce possible feedback of potentially hazardous voltages either caused by lightning
strikes or contact with high voltage power lines, the Canadian Electrical Code requires the
installation of a primary protector as per Rule 60-200 as noted below:
60-200 Provision of Primary Protectors:
(1) A primary protector shall be provided on each electrical communication circuit, except
as provided in Subrule (4).
(2) The primary protector shall be located in, on, or immediately adjacent to the structure or
building served and as close as practicable to the point at which the conductors enter or
attach.
(3) The primary protector shall not be located in any hazardous location as defined in
Sections 18, 20 and 24, nor in the vicinity of flammable or explosive materials.
(4) A primary protector need not be provided if no portion of the circuit is considered
exposed plant.
Primary protection must be provided on circuits considered exposed plant. Where located
outdoors, the
circuit shall be located below grade level and installed in a conduit. These
circuits shall not have any exposure to lightning or contact with power lines at all times.
Direct buried cable/
conductors are generally classed as exposed plant because they are
usually susceptible to lightning strikes.
7.2 Service Connection
In new homes, the telephone entrance cable (aerial or underground) terminates in the NIB
box located on the outside walls of your single-family residential buildings. It is usually
located close to the electrical meter. To gain access to the NIB box or NIB lid and to the
demarcation jacks, loosen the screws and optional customer lock located on the right hand
side of the NIB box or lid. With the outer door swung open, access to the demarcation
jacks and/or inside wire is now possible.
In accordance with regulations, TELUS must be contacted to determine the proper
demarcation point.
7.3 Demarcation Point
The terminals found on demarc blocks and protectors could be marked in a number of
ways:
