Controller Module Identification
The CMs can be inserted into a powered frame. To ensure that the system
power supply is not disturbed, a pre-charge resistor is connected in series
with one of the rear connector pins. The corresponding pin on the back-
plane connector is longer than any of the other power pins. This allows the
pre-charge pin to make connection before the others.
Vertical interval reference is required for Crosspoint switching tasks. This
is an analog video input which can be NTSC or PAL. This input is processed
to extract vertical sync and odd/even field (if any) information. A pre-
defined programmable logic device (PLD) is used to create a switching
strobe that is offset into line 10 for NTSC or line 6 for PAL. A video presence
detector interrupts the processor if the video reference is missing. If this ref-
erence is missing a fake sync is generated at a default asynchronous
interval.
Concerto has three Controller modules. Two of the modules are Ethernet
only. One Ethernet Controller is labeled
CRS2001 CONTROLLER 671-6381-xx
with an Ethernet interface of10Base-T and the other is labeled
CRS2001 FAST
CONTROLLER 671-6434-xx
with an
Ethernet interface of 10/100Base-T. The
third Controller is labeled
CRS-MC-C2 671-6495-xx
and can be set to allow
either Ethernet or Crosspoint Bus interface control. Do not mix Controller
types in a single matrix. See
for help in identifying Controllers; see
for the 3Gb/s board.
