1.1 General Features
The R&S®GB4000V provides audio, PTT and squelch to and from radios in a remote
location. The unit is compact and fits into any console. The R&S®GB4000V can be
connected to the radios using 4-wire E & M (analog line) or voice over IP (VoIP). When
connected using an analog line, either 4-wire E & M lines (PTT, SQ) or in-band tones
for E & M can be used. The available tones are 2040 Hz (PTT) and 2440 Hz (SQ). In-
band signaling is handled by the R&S®GB4000V, thus eliminating the need for other
external devices.
When used with the R&S®GB4000T touchscreen control unit, the R&S®GB4000V can
be connected to any of up to nine channels using R&S®Series4200 radios via VoIP.
