Monitoring
Video selected from input 1-128, or output 1-128
(Applies to PT-RES in 5/9/15/28 RU Platinum frames and PX-RES in a 9/15 RU Platinum
frames)
Video selected from input 129-256, or output 129-256
(Applies to PT-RES in 5/9/15/28 RU Platinum frames and PX-RES in 9/15 RU Platinum
frames)
Video selected from input 257-384, or output 257-384
(Applies to PT-RES in 28 RU Platinum frames)
Video selected from input 385-512, or output 385-512
(Applies to PT-RES in 28 RU Platinum frames)
External video sources include video from another frame.The external input is coupled to
this module through a rear BNC connector. It allows for monitoring of other SDI signals.
Using the VIDEO OUT BNC connector, the selected signal is sent to the re-clocking section.
The reclocking circuit retimes the data stream and removes jitter from the stream. Some
signal stream parameters (such as data bit rate, re-lockability, 3G/HD/SD, bypassing, etc) are
checked and reported. The signal from the reclocking stage is coupled to the output driver.
The output is in-polarity with the input data.
Various LEDs report status on the PT-HSRAEC-OM as follows

Notes
PT-HSRAEC-OM modules have 1 monitoring port per slot
Each PT-HSRAEC-OM module can only monitor one output at a time from an
output card on the same router
The PT-HSRAEC-OM uses these two classification categories: real output monitoring and
virtual output monitoring.
Real Output Monitoring
With real output monitoring, the output is routed after the final active stage of the video
channel. This type of monitoring provides the highest level of confidence possible that the
signal seen at the monitoring point is the same signal that will be seen "on-air."
