The RTS is an alarm indicating that the Request To Send status of the DCE is abnormal.


Alarm Severity Alarm Type


Communication alarm



Impact on the System

When the RTS alarm occurs, the DCE fails to transmit services. Consequently, the services are interrupted.

Possible Causes

The possible cause of the RTS alarm is as follows:

The DTE at the opposite end works abnormally because the cable is improperly connected, or the service configuration is incorrect.


  1. Check whether the DTE at the opposite end works well by following the actions:
    1. Check whether the cable is faulty. If yes, remove the fault.
    2. Check whether the service configuration is correct, including the settings of DTE and DCE, inter, slave or exter. Make sure that the service configuration is correct.

      After making sure that the DTE at the opposite end works well, the RTS alarm is automatically cleared.
