TESTING OUTSIDE
LINES
In order to operate properly, the system must receive toll-
quality dial tones at the network interface. To perform
this test use a basic rotary telephone, a Touch-Tone
telephone with a modular cord, or a telephone with clip-on
leads.
CAUTION:
Do not use a MERLIN II system voice
terminal for this test. It will not test for dial tones and
may be damaged.
At the network interface associated with the outside line
from which you cannot make a call, choose the
appropriate procedure from among those that follow.
