Description
Paid over $26,000 for each of these cards. RENTAL INSURANCE REQUIRED! Willing to discuss sale of cards if the I/O cards I have listed are sold.
A crosspoint card (EM0525) receives signals from the input cards and commands from the control card. The crosspoint card then performs switching as directed, sending signals to up to four output cards. Each crosspoint card can receive up to 512 inputs and distribute up to 128 outputs. The NV7512 crosspoint cards feature Time Domain Mulitplexing (TDM). TDM technology enables multiple signals to travel on a single cable by placing the incoming signals in a continuous stream. This enables signals to be sent between input cards and output cards, and between frames, using a significantly fewer number of crosspoint connections. In turn, this reduces the amount of physical space required to house the router frame. In addition, the crosspoint card is able to store and switch AES synchronous channels separately for mono switching. On the crosspoint card, memory is divided into four segments, one for inputs from the local input cards and three for inputs from up to three additional connected frames. For example, one segment of memory is used for Router 1, the current frame, the next segment is used for Router 2, the next segment for Router 3, and so on. Crosspoint Card Functions Each crosspoint card receives inputs from the local router and from any connected routers (up to four total). Local inputs are forwarded to a TDM mulitplexer and a TDM crosspoint circuit. The TDM multiplexer creates three copies of the signal, forwarding each copy to the expansion connec- tors. The TDM crosspoint circuit forwards signals to four output cards on the local router. Signals received from the expansion connections are forwarded to a TDM demuxer, which in turns sends the signals to the TDM crosspoint circuit. The TDM crosspoint circuit forwards a signal to four output cards on the local router.
