Jack Field Wiring Supplement
A jack field is a group of jacks at the control unit location that serves as a
point of administration for telephone wiring. This section tells you how to
construct a jack field and how to extend the network interface provided by
the local telephone company to the jack field. Also, this section describes the
hardware designed specifically to ensure the following:
●
●
●
A neat, reliable, and durable wire installation
Easy rearrangement, changes, and upgrades to your MERLIN Plus System
Simple line swapping and maintenance strategy
A permanent wiring run between the voice terminal and the control unit
should be installed for each voice terminal. Also, we recommend that you
plan and install wiring for future voice terminal locations. To install voice
terminal wiring, follow the instructions in the procedure "Constructing and
Connecting the Jack Field."
If the local telephone company provided a network interface that is far
removed from the control unit location or an RJ21-type multiline network
interface, you should extend the network interface to the jack field. Follow
the instructions in the procedure "Extending the Network Interface to the Jack
Field." See Figure 37 for a typical complete wiring installation.
If all necessary wiring is in place, go back to the beginning of this manual and
read "Step 1: Installing the Control Unit," and follow the instructions.
