ITR2000A Tone Remote Desk Set

Introduction to the ITR2000A Desk Set
The ITR2000A Desk Set is an effective tool for maximizing the flexibility of radio systems. When used
with a tone remote adapter, it provides numerous options for remote control of base station radio.
Control point distances are limited only by telephone line capabilities (usually 300 miles). The number
of desk sets that can be set up in parallel is dependent on radio system design.
The standard features include parallel status updating, four-frequency control, monitor, intercom, line
operated transmit light (LOTL), parallel transmit mute, programmable voice delay, and full-duplex
capability.
