Section 1: Getting Acquainted CP-220A Central Station Receiver
Beneath the "TIP" and "RING" designations, there are 9 screw terminals in
a row marked "MANUAL." Those numbered 1 through 8 correspond to Line
Card Slots 1 through 8 and can be used in the testing of Digital
Communicators without the need for a telephone line. Any Line Cards inside
the CP-220A can also be tested via this method.
At this point, the CP-220A Digital Receiver is ready to be programmed. The
CP-220A has many programmable features, called parameters, which can
enhance and customize its operation to best suit the requirements of your
Central Station. As of this printing, the CP-220A has 63 programmable
parameters, which include setting the following items:
• how messages appear on the display
• the date and time that appear on the display
• the operation of the internal sounder
• the words displayed in response to various events
• whether the standby battery is periodically tested
Each parameter can be selected and changed by using the keypad on the

of
the
receiver.
pre-programmed all of the parameters with values, called defaults, which
represent common choices of receiver operation. Because of these defaults,
little additional programming is often required, and the operation should
proceed quickly and easily.
All of the parameter values, whether they have been specifically
programmed or remain as specified by the defaults, do not require any
electrical power to be maintained in the CP-220A's memory. The obvious
benefit is that, were it ever necessary to move the receiver, all sources of
power could be completely disconnected and no re-programming would be
required.
Programming the CP-220A will begin in Section 2, which follows. At that
time, you may wish to start programming right away and you can do so –
simply by plugging the CP-220A into a source of AC power. However, the
receiver will soon "complain" that the connections it expects to see from the
"outside world" are missing, and you'll be unable to begin programming until
you address this problem.
