DUAL 2FXS+ MODULE

EXPANSION MODULES FOR THE TSU

The TSU Multiplexer FXS+ option modules provides four 2-wire interfaces that can operate in the PLAR, Tandem (MEGACOM), or FXS mode. The available modules provide 2- and 4-port voice interfaces that supply line current to station equipment. Two types of FXS+ modules are currently available. The original FXS+ modules support message waiting and higher ringing voltages. The new, second generation FXS+ modules are used for most traditional FXS+ applications.
