lines.
Refer to the topics referenced below depending on your
wiring needs.
●
If you decide not to have direct connections from the
voice terminals to the control unit and the building
wiring and jack fields are not installed, you need to
construct a jack field for the voice terminal wiring.
Follow the instructions in “Constructing a Jack Field
for Voice Terminal Wiring,” found on page 2-35.
●
If the local telephone company provided a 50-pin
(RJ2 l-type) connector interface but the wiring from
the network interface to a jack field for outside lines is
not installed, you may want to construct a jack field for
outside line wiring and extend the network interface to
it. Follow the instructions in “Extending the Network
Interface to the Jack Field for Outside Lines” on page
2-41.
●
If all necessary wiring is in place, go on to “Installing
the Control Unit” on page 2-50 and follow the
instructions.
See Figure 2-2 on page2-13 for an illustration of
MERLIN II system wiring with jack fields.
NOTE:
The jack fields for the system shown are
constructed with Z122C apparatus boxes, which
are attached to each other using a tongue-in-
groove design and mounted to the left of or under
the control unit. The Z122C boxes come with 2A
retainers for holding wiring adapters, such as the
cutdown-to-modjack 2601A adapter. If 2A
retainers are not required, Z122B apparatus
boxes can also be used. See the following
heading, “Constructing a Jack Field for Voice
Terminal Wiring.”
