CTP Systems CTPhone

1900 system adds wireless phone service to
new or existing Private Branch Exchanges (PBX), Centrex service, or key
systems. The CTPhone 1900 system operates in both single building and
campus environments.
Components of the CTPhone 1900 system are base stations, handsets, a
CTPhone Controller, and CTPhone Manager software. Base stations are
installed throughout a facility to relay calls between the portable handsets
and office telephone system. The CTPhone Controller connects to an
office telephone system and accommodates one or two base stations and
up to 32 CTPhone handset users. Each eight-channel base station pro-
vides eight channels (each four-channel “Mini” base station provides four
channels) and up to 333,560 square feet (31,000 square meters) of calling
coverage.
CTPhone handset users have access to the office telephone system fea-
tures in addition to being free to make and receive calls away from their
desks. The handset is small, lightweight, and easy to use. It also features
a display area for alphanumeric information and icons that report handset
status.
The CTPhone 1900 system operates in the 1920–1930 MHz range, which
is specifically set aside by the FCC for unlicensed Personal Communica-
tions Services (U-PCS) in the United States.
