Telex IP-223 - Operating Modes

Overview

Operating Modes
The IP-223 is capable of operating each audio port in different modes:
Local Mode - Allows the radio to connect directly to the IP-223 allowing for simple migration and local control
of the radio.
Tone Mode - Allows the IP-223, based on Ethernet traffic, to generate required key tones required to control
industry standard tone-equipped radio circuits. This allows an existing tone decoder and radio to be
connected. This mode also supports a parallel analog console.
Console Mode - Allows the use of existing tone-based consoles. The IP-223 decodes industry standard tones,
converts it to Ethernet traffic to another IP-223 that can be in tone or local mode.
Phone Mode - Using a PIB (Phone Interface Box) or TDI (Telephone Dispatch Interface), a line on the IP-223 is
used to connect to an analog phone line.
