Port Type Assignment

Each port must be assigned a port type. A port type defines is a set of characteristics that make the port exhibit a specific behavior. These characteristics typically include but are not limited to the following…

-Audio loop back on or off

-DTMF muting on or off

-DTMF command decoding enabled / disabled

-Transmitter carrier delay on or off

-Telemetry generation to port transmit output

-Etc…

Port types

Repeater

The repeater port type loops back audio, adds carrier delay, mute DTMF audio, etc. In general it behaves the way you would want a repeater to behave.

Link

A link port type is used for all RF or VOIP point to point link circuits which are part of the network “backbone”.

Remote Base

The remote base port type is a used for HF/VHF/UHF remotely controlled base stations. The remote base port will not accept DTMF commands from the outside world and will not generate transmit telemetry. The control system will make the remote base radio sound as must like a manually operated transceiver as possible. The remote base can be frequency and mode agile and takes additional parameters to assign the radio control format necessary to control the remote base radio.

IRLP

The IRLP port type is similar to a remote base port but is used for public VOIP networks like IRLP, Echolink and others.

VOIP Link

The VOIP Link port type is similar to the Link port type but adds additional conditions to handle radio over IP signaling.
