Control Signals: In DCE mode, DSR turns “ON” immediately after the
terminal raises DTR; DCD turns “ON” after recogniz
ing the receive signal from the line; CTS turns on
after the terminal raises RTS
Carrier: The carrier is switch selected either continuous operation or
switched operation, controlled by RTS
Surge Protection: 600W power dissipation at 1 mS and response
time less than 1.0 pS
Power: No external power required, uses ultra low power from EIA
data and control signals
