Connect The Outside Lines To The Control Unit - AT&T MERLIN 820 Installation Manual

CONNECT THE OUTSIDE LINES TO THE CONTROL UNIT

Any outside line may be connected to any of the line jacks A through H on the
control unit. To simplify future line administration, however, you should connect
your outside lines to an unbroken sequence of jacks beginning with A (for ex-
ample, the sequence A, B, C, D, and E, rather than B, C, E, G, and H). After
you have completed the installation, you can program a line-selection sequence
and individual line appearances for each of your voice terminals by following
the instructions in your administration manual.
You need the following items from the Control Unit Installation Kit to connect
the control unit to the jacks for your outside lines, whether they appear at the
jack field or at the network interface.
System directory
Modular line cords
You need one 7-foot cord for each outside line.
Green-on-white line cord labels
They're marked A, B, C, etc. You need a matching pair for each outside line.
Now do this:
1
Decide which outside line number to assign to each outside line jack
on the control unit.
TIP: The outside line numbers are the telephone numbers listed at the
network interface or on the left door of the box in the jack field contain-
ing the jacks for your outside lines.
2
Write the telephone number you assign to each of the line jacks on your
control unit in the appropriate space in the system directory.
3
Beginning with the pair of labels marked A, label each modular line cord
at both ends with matching line cord labels.
4
Plug one end of the line cord labeled A into the outside line jack labeled
A on the control unit.
5
Plug the other end of cord A into the jack in the jack field or at the net-
work interface for the outside line that has the same telephone number
you have assigned to line jack A on the control unit.
TIP: To find the correct jack in the jack field or at the network interface,
refer to your system directory, and follow the labeling at the jack field
or network interface.
6
Follow the same procedure with the remaining line cords until you have
connected all your outside lines to the control unit.
CAUTION: Do not run cords inside or on top of air plenums or ducts, along
hot pipes, or across walkways. If you use staples to attach the cords to a
wall or baseboard, be careful not to pierce the cords.
