Features
VoiceXtender (VX) modems provide the following features:
❚ Increased modem data rate to 28.8 Kbps
❚ Enables the maximum performance through a voice modem-CODEX
connection
❚ Caller Number Delivery and Signaling
❚ 902 to 928 MHz operating frequency
❚ Selectable channels
❚ Selectable output power
❚ Optional omnidirectional or directional antennas
❚ Power on and radio synchronization status indicators
❚ Hub (several co-located terminals) configurability

The VoiceXtender replaces the wired connection between a standard telephone
and the on-premises switch or centrex with a radio link. Both foreign exchange
station (FXS) and foreign exchange office (FXO) loop-start signaling are
supported. The VoiceXtender provides a standard ringer current for the
telephone ringer.
With the Caller Number Delivery feature, modulation is digitized by the VX
64 and converted at the receiving end within the specified three seconds.
Applications
VX modems can be configured for point-to-point applications to provide a radio
link between telephone devices. Several VX modems can be connected in a hub
configuration to allow even greater flexibility in the arrangement of telephone
equipment.
