multi-chassis routers as well as dual or quad outputs. A switch is
included to select one of four synchronizing inputs. A list of data rates
supported by the HO-33120 Output Board is shown on page 79 .
Protected path operation requires HO-33120 Output Modules in the
paths to be protected.
TRX-DM-33100
Digital Matrix Board - 128 x 128 for use with 128 and 256 frame
Contains 32 instantiations of a 32 x 16 crosspoint IC. It handles both SD
and HD data rates and is used in both the 128 and 256 chassis. It has a
memory refresh circuit which is used to keep the configuration of the
crosspoints in the event of some power interruption to the controlling
element. One card is needed for all configurations in the 128 chassis and
1, 2, or 4 are needed for the 256 chassis depending on the needed matrix
size.
TRX-DM-33512
Digital Matrix Board - 256 x 256 for use with 512 frame
This module consists of two circuit boards interconnected, each with a
256 x 128 matrix function. The matrix board uses redundant power-con-
ditioning circuitry and 144 x 144 crosspoint ICs (used as 128 x 128) each
with its own control circuit. A 512-chassis, fully stuffed to 512 x 512
inputs and outputs, requires four of these modules.
Options
Additional video signal cards
Additional input, output, and matrix cards can be selected for spares or
an additional level of signal routing.
Power Supplies and Fans
A redundant power supply and spare can be added if desired.
