Off-Premises and Basic
Telephones
Your basic Touch-Tone telephone is now connected to
the MERLIN™ communications system. The
technologically advanced MERLIN system control unit
enhances your telephone by providing many special
features. You can access these features by using dialing codes and switchhook signals, and you can communicate with all other MERLIN system users via an
intercom network.
GETTING STARTED
Important facts to remember for better performance:
Know the switchhook operation
Now that your telephone is part of the MERLIN system,
the switchhook still disconnects calls, but it also sends
signals that allow you to use the system’s convenient
features.
To send a signal, press the switchhook down firmly
as far as it will go and then release it. If you do not
press the switchhook long enough, the signal does not
work. A longer than necessary press will disconnect
the call.
Know the different dial tones and rings
Intercom and outside dial tones sound different. Intercom dial tone is what you hear when you first lift the
handset to place a call. Intercom, outside, and transferred calls each have a distinctive ring that you should
learn to recognize. (Intercom = 1 ring; outside = 2
rings; and transferred = 3 rings.)
