Applications; Physical Description - AT&T Callmaster Series Reference Manual

The S203A Speakerphone is an analog speakerphone with Auto-Answer and Automatic Discon-
nect capabilities. The S203A can be used in conjunction with any single-line analog set (an addi-
tional 267A2 bridging adapter is included for this arrangement) or as a stand-alone unit. When it
is used in a stand-alone operation, the S203A provides no dialing functionality. When the Auto-
Answer feature is enabled, an incoming call will cause the S203A to automatically go off-hook
and emit a special tone that is heard by both the calling and called parties. This tone indicates
that the call has been automatically answered. The S203A Speakerphone automatically adapts
to room acoustics, thereby dramatically improving the sound quality.
Note: This speakerphone is available with a wall-mounting bracket.

Applications

The S203A Speakerphone can be used with the DEFINITY G1, G2, G3, System 75 and
System 85. Its Auto-Answer and Auto-Disconnect capabilities make it very suitable for environ-
ments where hands-free mode of answering is desirable. Such scenarios include hospital emer-
gency rooms, laboratories, nursing homes, storerooms, and warehouses.
