Single-Line Telephones 6
In addition to system telephones, you can connect industry-standard touch-tone or rotary dial
telephones—and even some feature telephones (which have built-in calling features)—directly to
the system. You can also combine single-line telephones on the same extension with system
telephones or other devices, without using expensive adapters or connectors.
Single-line telephones can do many of the things that system telephones can do, and you can
save money by using them in certain situations when a system telephone is not needed. Follow
these guidelines when using single-line telephones:
■ Use single-line telephones as power-failure backups; system telephones will not work. If you
connect single-line telephones to the first two extensions on the PARTNER ACS processor
module, users can place and answer outside calls on the first two lines. If you connect a
single-line telephone to the first extension on each 206 module, users can place and answer
outside calls on the first line of each 206 module. You can connect single-line telephones in
combination with system telephones at power failure extensions, or you can simply keep
spare single-line telephones at those extensions to serve as replacements in case of a power
failure.
■ To use a system feature, press # (in place of f used on system telephones) followed by
its two-digit code when you hear intercom dial tone. For features that use
i on system
telephones, dial only the two-digit code when you hear intercom dial tone.
■ To use a Speed Dial number, press # followed by its two- or three-digit code when you hear
intercom dial tone.
■ If Call Waiting (#316) is assigned to an extension with a single-line telephone connected, the
user hears a call-waiting tone (two beeps) when a second call comes in to the extension. The
call-waiting tone is not repeated.
■ Use the switchhook on a single-line telephone to place calls on hold, park a call, transfer a
call, answer a call-waiting call, or set up a conference call.
■ If the single-line telephone has a message light, use it to notify users of messages. If you have
a voice messaging system, the light indicates that a message has been left in your mailbox.
On a single-line telephone, the message light flashes when the telephone is idle to indicate
that the extension has received a message.
Ringing Patterns 6
Single-line telephones have these ringing patterns:
■ An outside call will ring... ring... ring.
■ An intercom call will ring-ring... ring-ring... ring-ring.
■ A transferred call, or an unanswered transferred or parked call that is ringing back, will
ring-ring-ring... ring-ring-ring... ring-ring-ring.
