Doorphones allow visitors to signal extensions by pressing a button on
the doorphone; the person who answers a doorphone call can then
speak with the visitor at the doorphone. A doorphone is especially useful
for providing access to offices or departments after hours. For example,
you can install a doorphone outside your building entrance to allow
visitors to ring telephones inside the building when the receptionist is not
there and the front door is locked.
The system supports up to two AT&T PARTNER Doorphones or any
number of AT&T Universal Doorphones. Universal Doorphones offer a
door unlock feature and can be installed in addition to PARTNER
Doorphones.
Loudspeaker paging systems allow you to broadcast a message over a
large area, by connecting the paging system directly to the PAGE jack on
the processor module. The system supports all AT&T paging systems
including the entire PagePac® line, and most paging systems from other
manufacturers. In addition to its numerous paging features, the
PARTNER PagePac provides doorspeaker and door unlock capabilities.
For information on how to use a loudspeaker paging system with the
system, see Chapter 5.
PARTNER PassageWay™ Solution allows you to combine your
Personal Computer (PC) running Microsoft® Windows™ 3.1 with your
phone. You can then use your PC for tasks such as dialing out from an
electronic phone list, logging phone calls, and programming your phone.
Music-on-hold systems allow you to play recorded music or messages
to callers while they are on hold, by connecting the audio source to the
processor module. The system supports the AT&T Magic on Hold system
and most models from other manufacturers. (If you use equipment that
rebroadcasts music or other copyrighted materials, you may be required
to obtain a license from a third party such as ASCAP or BMI.)
Remote Administration Units (RAUs) allow you to perform System and
Centralized Telephone Programming from a remote location.
Extra alerts help make users aware of incoming calls. For example, you
can use an audible alert (chime, horn, or bell) to replace a phone ring in a
noisy area, such as a factory. Similarly, you can use a visual alert (strobe
or light) to replace a phone ring in a quiet area, such as a library. AT&T
offers several compatible alerts.
Speakerphones provide hands-free two-way operation of a phone
without lifting the handset. Combining a speakerphone with a system
phone or a standard phone in a conference room or office is an
inexpensive way for several people at a meeting to conference in other

parties. (System phone speakers are designed for individual use—not
group use.) The system supports the AT&T S203 speakerphone and any
industry-standard speakerphone.
