General Information
Description
Parts Enclosed
This unit comes assembled on a
metal
baseplate. It con-
verts a standard push-button phone to a display phone that
can be used with Telecenter
V, Telecenter IV, Telecenter
TCS, Telecenter System 21, or TCll00
systems. It has a
16-digit LCD readout and a "beeper" to annunciate call-ins.
The TC4221 can be used as a direct replacement for a TC4220,
but it offers a number of new features as well, notably its
capability of being individually
addressed in a Telecenter V
and Telecenter System 21 system.
The following parts should come with the display:
4 1" x 2 1/2" double-sided foam strip, for fastening the
display to the telephone.
4 Nine-inch, six-conductor modular phone cord.
Number of Displays
The display matches the Rauland TC4204 Administrative
Telephone. It can be used with many other DTMF (dual-fre-
quency, multi-tone) desk phones, the only limitation
being
aesthetics. Figure 1 shows a typical placement.
Telecenter V and Telecenter System 21 systems have a
single display driver that can support up to 2,000 feet of
cabling and 16 displays. Each display may be assigned its own
address with its DIP switch (see "Setting the DIP Switch," the
final section of this manual).
Telecenter 1100, Telecenter IV, and Telecenter TCS sys-
tems can support up to 1,000 feet of cabling and three displays
per display driver. Telecenter 1100 systems have one display
driver, Telecenter IV systems have two display drivers, and
Telecenter TCS systems have six display drivers.
