Crosspoint Card
The crosspoint (XPT) card contains the switching matrix:
There are no connectors on the XPT card, but it does have an alarm LED and a power LED.
The power LED is green when the control card has good power and red if power is faulty.
The alarm LED is red when an alarm condition exists (such as the absence of a video reference).
The alarm LED is green otherwise.
I/O Cards
The I/O cards are labeled according to their type and have an alarm LED and a power LED.
The power LED is green when the control card has good power and red if power is faulty.
The alarm LED is red when an alarm condition exists (such as the absence of a video reference).
The alarm LED is green otherwise.
3Gig
The 3Gig card has 16 “coax” inputs and 16 coax outputs:
The “3Gig” I/O cards support video, with or without embedded audio, at 2.966Gb/s, and
2.97Gb/s video rates as well as a number of HD and SD bit rates and formats. The 3Gig cards
reclock at 270Mb/s, 1.483Gb/s, 1.485Gb/s, 2.966Gb/s, and 2.97Gb/s. The 3Gig cards bypass re-
clocking for other rates. Video reference must be nominally 800mV p-p and bi-level or tri-level in
nature.
The 3Gig cards also support DVB-ASI.
AES
The AES card has 16 “coax” inputs and 16 coax outputs:
The AES router switches AES3id audio.
Each of the 64 AES inputs is a stereo pair. Similarly, each of the 64 AES outputs is a stereo pair.
The inputs are switched as stereo pairs. There is no other switching option for the CR6464-AES
routers.
