available when a second NR-33000 is added; this would provide four
monitor ports.
• The SR-33500 Sync/OPM board, on the TRX-NXT-512x512 frames, pro-
vides four monitoring ports.
• The TRX-SR Sync/OPM board, on the TRX-NXT-256x512 frames, pro-
vides four monitoring ports.
• The TRX-OPM board, on the TRX-NXT-128x256 and TRX-NXT-
512x1024 frames, provides four monitoring ports.
Symmetric Frames
For configurations that require multiple frames, the monitor signals are
brought through a Port expander used as a combiner (see
Monitoring with
Expanded Systems ).
Asymmetric Frames
The TRX-SR Sync/OPM and TRX-OPM boards provide four monitor
inputs to accommodate cascading multiple frames into a single output
monitor stream. These boards are specific to the asymmetrical routers, for
more information see Asymmetrical Frames
on page 200 in the Monitoring
section.
3Gp/s Output Monitoring
The TRX-GPMEZ-3G mezzanine module on the TRX-HO-3G base Output
Module in the Trinix Symmetrical frame, receives a stream that is
1080p59.95, it is the down-converted to 1080i59.95.
The TRX-SR Sync/OPM and TRX-OPM boards support 3Gp/s Output
Monitoring in the asymmetrical frames.
Signal Flow
Trinix is a three-board routing system, where the input board, output
board, and matrix board are the basic modules.
The signal flow through a 128 x 128 routing system is shown in Figure 25
on page 63 as an example. Inputs are received and outputs are delivered to
the rear of the frame directly with a connection to the rear panels (no
cabling).
