The UIC supports all of the following features:
• Channel and Bank control of receiver and transmitter modules (2 banks of 16 channels each).
• Detect the mode (analog or P25) of an inbound call on the receiver and report to the console.
• Receiver squelch selection (muted or unsquelched) controlled by the console.
• Clear the encryption keys from all encryption-equipped radio modules through the UIC’s front panel Zeroize Key
push button.
• Control and monitoring of 8 digital general purpose input and output (GPIO) signals from the console. The 4 inputs
are 10 mA max., 0 to +1 Vdc low / +2 to +13.8 Vdc high. The 4 outputs are 20 mA max., 0 Vdc low / +5 Vdc high.
• Control and monitoring of 8 analog GPIOs for use with external equipment. The 4 inputs are 0 to +3.3 Vdc, 3 k
impedance. The 4 outputs are 20 mA max., 0 to +3.3 Vdc. Analog I/O resolution is10 bits (3.22 mv / bit = 1 LSB).
• Programmable simplex mode operation.
• Local repeating under the control of the console, or automatically when the UIC is not connected to a console.
• Current draw of 200 mA maximum.
• Audio Reception and Transmission using IMBE™ (P25) or u-law PCM (analog).
• Passes all received P25 LCW and ESW data to the console (NAC, TGID, MFID, ALGID, KID, etc.).
• Full end-to-end digital encryption if supported by the console and subscribers.
• Outbound audio buff ering when transmitting P25 mode calls, with a programmable buff er length.
• supports DFSI v2 P25 Packet Data.
