Port Type for Port 4
For details on the selection method, options, and possible combinations, see Port 3. The
following is a description of the additional combinations that apply to Port 3 and Port 4 only.
Radio, Conventional, radio type, max. number of repeaters, modem
Direct FM modulation for conventional radio. For all parameters that appear italicized above,
open the drop-down list and select the corresponding value. If you cannot find the requested
value on the list (like a radio type), select the “General” parameter (for example, General
Radio).
Radio, Trunking, radio type, trunk system, modem

select the corresponding value. If you cannot find the requested value on the list (like a radio
type or trunk system), select the “General” parameter (for example, General Radio).
Line, Multi-Drop Half-Duplex
For multi-drop half-duplex wire line communication, using the Line Modem board.
Line, Full Duplex (2w/4w), Sync
For full-duplex (2w/4w), synchronous wire line communication, using the Line Modem board.
Line, Full Duplex (2w/4w), Async
For full-duplex (2w/4w), asynchronous wire line communication, using the Line Modem
board.
Line, Dial-up, Async
For asynchronous wire line communication using the dial-up Line Modem board.
Microwave, Full-Duplex, Sync
For full-duplex, synchronous microwave communication, using the Line Modem board.
Microwave, Full-Duplex, Async
For full-duplex, asynchronous microwave communication, using the Line Modem board.
Microwave, Half-Duplex
For half-duplex microwave communication, using the Line Modem board.
