2.0 General Infomation The CPI TTP(N) series termination panels provide a reliable means of interfacing a tone remote to a two way radio base station. The TTP series can be used with any tone remote that uses the industry standard EIA sequential tone format such as the CPI TR series remotes. The TTP(N) series panels are available in the following configurations.
.0 Tuning The TTP(N) termination panels 2175 Hz notch and bandpass filters and line balance adjusters have been factory set. These adjustments have been “painted” and should not require readjustment in the field. If it does become necessary to “retune” the panel, the procedure is as follows: TX Audio notch filter 1) Connect: Signal generator (600 ohm) set at 2175 Hz.
Line In Adjustment Auto level adjustment: The TTP(N) series has an AGC (automatic gain control circuit). This circuit eliminates the need to adjust the line input level from the tone remotes or consoles. Selection of automatic or manual gain control is selected by the JP2 jumper. Automatic gain control - JP2 should be set in the 1&2 position. Manual gain control - JP2 should be set in the 2&3 position. The line input level is adjusted via R104.
