the point of connection to the outside lines from the network interface, which is provided by the local telephone company, to jacks in a jack field for the outside. 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 2-2on 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.”
