RTS SSA-324 Specification Sheet

systems. In addition, it can optionally interconnect “Calls” or tally signals between systems. Each SSA-324 includes two two- wire to four-wire converters. The four-wire interface can deliver and accept high level signals. An SSA-324 can also function as a two-wire to two-wire interface by interconnecting the two individual interfaces at the four-wire level. The SSA-324 does two voice channels when used as a dual two-wire to four-wire interface, and one voice channel when functioning as a two-wire to two-wire interface.
