Overview
The SMPTE 269M Fault Reporting system, also known as a SMPTE “alarm”, provides indication if
one or more frame modules encounter a fault or an abnormal condition. The CMA-8011A module
provides a jumper to enable SMPTE-269M fault reporting. The card connects by means of an internal
interface circuit to an auxiliary
telco connector on RossGear 8000 series frames. When the frame
connection is interfaced with a customer-designed system of LEDs or audible alarms, faults can be
traced to a specific frame when a card fault occurs within that frame.
The following diagram illustrates a general arrangement for SMPTE 269M alarm reporting:
