VX-400/528R/XL

The VX-400/528R XL assembly occupies a crosspoint slot in a Series 2 528 style router. It consists of a carrier for four of the TDM Crosspoint submodules, and works along side video crosspoint cars in the 528 system to create a combined TDM audio / video switching matrix. It can only be located in slots 0 or 2 of the 528 frame. This card supports TDM connections from input slots 0-11 and output slots 22-34 in the 528 system.

Details
Technical Specs

the VX-400/528R XL Video Crosspoint Card is the central component in the UT400 528 routing switcher. The same card can be placed in any one of the four crosspoint card slots in the system without changing any configuration settings on the card.

 

The card uses four discrete 144 in x 288 out crosspoint sub-modules installed on a carrier card to comprise a 576 in x 288 out fully differential crosspoint array that is capable of signal from
DC to 3.2Gb/Sec.

 

The card also contains voltage regulation circuitry that converts the two possible 48 volt inputs to 3.3V, which is used by the carrier and further regulated to 1.2V and 1.8V on the crosspoint
sub modules. Switching is controlled via two discrete control busses from the Frame Control Module.

Circuit Description

Each of the 576 input signals differential input signals is carried to a single crosspoint module, where it is resistively split and applied to two different 144×144 crosspoint chips.

The outputs of the four crosspoint modules are passively combined, and coupled with the proper switching commands from the Frame Controller Module, allow for the large crosspoint array size.

The control circuitry that decodes the control bus’s from the Frame Control Modules is made up of an FPGA and a DSP co-processor that monitors critical crosspoint functions as well as implementing the switch commands sent to the card by the Frame Controller Module.

Controls and Indicators

Controls:

Reset Switch (SW2) –  Resets and restarts all processing activity on the card.

SW1 –  factory set dipswitch which will not require any user adjustments.

P1 –  Standard UT400 diagnostic port that provides detailed operational status and control for this card.

 

Indicators:

DS1 – FPGA Load – Green – Illuminated when the FPGA is configured. If it is off, the card is not functional.
• DS2 – PSA FAIL – RED – Illuminated when the ‘A’ 48V to 3.3V converter is non-functional.
• DS3 – PSBA FAIL – RED – Illuminated when the ‘B’ 48V to 3.3V converter is nonfunctional.
• DS4 – Health – RED – Illuminated when the internal monitoring circuit detects ANY non-ideal conditions on the card.
• DS5 – FCM COM – Yellow – Illuminated when this card is selected by the Frame
Communication Module
• DS6 – Undefined
• DS7 – Undefined
• DS8 – XP-PSOK – Green – Illuminated when all 8 PS sub module power supplies
are OK.
• DS9 – SEAT – Green – Illuminated when all rear panel sampling points are satisfied, indicating that the crosspoint card is seated properly.
• DS10 – SG Activity – Indicates that the local Scangate part is active.

• Crosspoint LEDs (Active) – The yellow LED pulses continuously when conditions are normal. A solid LED indicates the ‘standby’ crosspoint in a redundant system.
