WARNING:
National and local building codes specify the type of cable required
for telecommunication wiring. For example, indoor wiring (DIW
cable) cannot be used inside or on top of air plenums or ducts,
along hot pipes, or across walkways.
Consult your local ordinances and regulations for proper cable
selection.

Wiring a Telephone for Two Voice Pairs

If an analog telephone requires either the Voice Announce to Busy feature or
voice and data operating independently, use a bridging adapter to assign two
adjacent odd/even telephone jacks (for example, 01 and 02, 13 and 14) on an
analog telephone module to that telephone. This provides the telephone with
the two voice pairs needed to use these features. See
NOTE:
The numbers of these telephone jacks are boxed on the system forms. In
Figure 3-39, the label on the bridging adapter refers to the default dial plan
extension number, not the telephone port number.
The even jack on the bridging adapter should be connected to the
odd-numbered telephone port, and the odd jack on the bridging adapter
should be connected to the even-numbered telephone port.
To avoid introducing power supply noise into system wiring, allow
at least 3 in. (7.62 cm) of clearance between the basic carrier's
power supply and any wiring or termination hardware located to
the left of the control unit.
