How the system works:
The TSAM unit works with standard voting receiver systems,
consoles, and base stations. When a mobile or portable calls
the dispatcher, the comparator selects the best receiver site.
The TSAM unit uses vote indicate lines from the comparator to
determine the best transmitter to use for the next transmission.
The TSAM unit routes the transmit audio to the appropriate
transmitter and provides a steered transmitter indication to the
console.
Home Site Revert
The TSAM unit can return the steered transmitter to a user-
programmable home site after a period of system inactivity.
The next transmission will be sent out over the home site.
Manual Select
The dispatcher can use the Manual Select function for an
initial transmission when a field unit is not in the home site
coverage area. When the field unit responds, the system will
steer to the proper site for the next transmission. The Manual
Select function can be used to select the proper site when
multiple units call in at the same time
Optional Secondary Operation
The optional Secondary Operation function allows a steered
base to be moved to a secondary channel for handling special
details
or tactical communications. The TSAM unit
automatically disables the comparator, changes frequency of
the base station, and re-routes transmit and receive audio to a
secondary dispatch console.
The secondary base operates
completely independently from the main steered channel.
