Circuit Assurance
Choosing option 2 in the Software Switch Menu takes you to the Circuit Assurance
Menu. On dedicated (DDS) circuits, the transmitter and the CTS output can be
configured to go ON only when a working communication circuit is established. If
you use Circuit Assurance with DDS services, enable it on only one end of the
communications link. For Switched-56 services, enable Circuit Assurance on both
ends of the circuit. When Circuit Assurance is disabled, the transmitter and CTS
operate without regard to the receiver state.
