TN856 CI-IP-223 Telex IP-223 Network Remote Adapter
The Telex IP-223 IP Network remote adapter provides a reliable means of remotely controlling up to two Zetron
base stations. The adapter can be used in conjunction with Telex model C-6200, C-Soft, IP-1616, IP-2002 consoles.
The IP-223 is interconnected to the distant remote control console(s) by means of any available Wide Area Network
(WAN) or Local Area Network (LAN) connection.
The Telex IP-223 is capable of operating in several distinct modes:
Local: The radio is connected to the IP-223 directly using a similar connection pin-out as the DSP-223 and is
controlled by Telex VoIP consoles. This mode supports direct serial control of several radio models.
Tone: The IP-223 decodes Ethernet traffi c from Telex VoIP consoles and encodes industry standard tones for
control of existing tone remote adapters. This allows a migration path to VoIP communications and keeps legacy
equipment.
Console: The IP-223 decodes industry standard tones from existing legacy consoles and converts it to Ethernet
traffi c to another IP-223 that regenerates the industry standard tones for control of existing tone remote adapters.
Phone: Using the PIB223, a line on the IP-223 is used to connect to a standard PSTN phone service.
Smart Repeater: In this mode, the IP-223 can be made to link two repeaters together. The IP-223's are eff ectively
back-to-back on the network.
