DoubleTalk
allows for two-way satellite links
to be transmitted concurrently in
the same segment of transponder bandwidth,
thereby saving users significant
space segment costs. It is inserted
into the IF layer between the frequency
converter and the modem, and is completely
independent of any modem settings.
DoubleTalk at hub in multipoint network
reduces bandwidth requirements by up to 4 MHz
Multiple DoubleTalk
units can be scaled across transponder bandwidth for
additional efficiency
Bandwidth of outbound
carrier can be up to an entire transponder
Supports all common
modulations and FEC types
Makes available additional bandwidth for
revenue-bearing traffic
Upgrade existing networks or design into
new ones
Easy setup from front panel or remote terminal
DoubleTalk technology now licensed and
available in new Comtech/ EF Data Corporation modem for
SCPC applications
