Connection of Multiple Base Stations with the Link
Cables
This section discusses various configurations of multiple base
stations using link cables. Multiple base stations may be
connected via standard 2-wire and 4-wire intercoms without
additional link cables between them. They still transmit and
receive intercom 1 and intercom 2 audio normally from the
beltpacks.
FIGURE 56. Multiple base stations with only 2-wire intercom
channels 1 and 2 connected between them
However, by connecting multiple bases together via link cables,
in addition to any 2-wire or 4-wire audio connections in use, the
feature set of a single base becomes available to the whole
system. This feature set also includes base stations that have
their transmitters off in order to conserve RF spectrum.
These features are:
• (WTA) Wireless talk-around channels 1 and 2 shared
between base stations.
• First-On-Latch-Out of beltpacks extended to base stations
with their TXs off (when beltpacks are in push-to-transmit
mode).
• Automatic beltpack TX power control extended to base
station with their TXs off.
• Automatic beltpack user ID assignment extending to base
stations with their TXs off.
• Beltpack TX and Talk shutdown via the base front panel
extended to base stations with their TXs off (when beltpacks
are in push-to-transmit mode).
• Beltpack Talk shutdown via the base front panel extended to
base stations with their TXs off (when beltpacks are in push-
to-talk mode).
