Overview
The SMPTE 269M Fault Reporting system, also known as an SMPTE “alarm”, provides indication if
one or more frame modules encounter a fault or an abnormal condition. The MUX-8552A 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 and 8000A 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:
