Operating the TSG-3800 Selecting the Input Reference Signal Input Signal Faults The input signal and measurement data is checked for errors each second. If no errors are found, the input is considered valid and may be selected as the reference input.
Operating the TSG-3800 Selecting the Input Reference Signal Synchronization Status Messages Synchronization Status Message (SSM) provisioning is a dual purpose setting. When using the Automatic SSM Mode setting on the inputs, it may be used indicate the SSM quality level for signals that are SSM-capable. This setting may also be used in conjunction with the SSM Alarm Mode parameter to indicate that the received SSM is below this provisioned SSM.
Operating the TSG-3800 Selecting the Input Reference Signal value. The operator may also set the port to disregard the received SSM and always output the provisioned SQL. The SQL received or provisioned is passed to the frame generators for determining the output SSM when in Locked mode. If inputs are not receiving SSMs and are provisioned below the selected clock’s stratum level, the clock enters holdover.
Page 87
Operating the TSG-3800 Selecting the Input Reference Signal Priority Position The primary selection criteria is the input signal priority level described in Priority Level, on page 83. The system selects the highest priority level (1-4). The selection order proceeds from highest priority to lowest priority. When two or more input signals have identical priority levels and the levels are the highest priority setting, the system uses the signal with the highest Synchronous Quality Level (SQL).
Operating the TSG-3800 Setting Up Input Reference Controls Best Mode In the Best mode, the TSG-3800 uses Input priority, SQL, input stability, and position to automatically determine the best input signal as the reference signal. Input stability refers to measuring input signal noise and choosing the best input signal based on this noise measurement (the best signal has the least noise).
