Polycom®Vortex®EF2201
DSP-based hone add for installed conferencing a lications
The ideal “ hone add” for installed conferencing a lications, the
EF2201 makes tele hone interfacing easy. With a variety of control
options, built-in DTMF dialer, and one-cable connection to other Vortex prod-
ucts, the EF220 simplifies the addition of telephone calls to your audio or
video conference.
When participants can't make it to a video con-
ference, or can only drop in for a short time, it's
easy to accommodate their needs. The Vortex
EF220 links directly to an analog (PSTN) tele-
phone line, connecting outside callers to your
meeting. In addition to providing crystal-clear
telephone audio to all participants, the Vortex
EF220 significantly reduces background noise
on the phone line, keeping unwanted sounds
from interfering with your conference. As the
next generation of digital hybrid telephone inter-
faces, the Vortex EF220 interfaces with other
Vortex products through a digital expansion bus.
Telephony signals are communicated with a
Vortex EF2280 over the digital P-bus channel of
the EF Bus, without the need for analog input or
output on the EF2280.The EF220 can be con-
trolled via RS232, Vortex Expansion bus, and
front panel controls. Additional features are
audible ring indications, user-configurable entry
and exit tones, up to 256 speed dial memories,
and controllable levels of DTMF and dial tone
signals. The full cross-point matrix allows users
to determine how the input and output signals
are sent to and from the telephony interface.
Settings are configured with Conference
Composer software (provided), and can be stored
as user presets.
