Description
The CNTL module controls and manages the RMX 2000.
The CNTL module has an ComExpress Pentium-M
1.4GHz processor, a 40GB hard disk drive, 1GB Compact
Flash and 1GB of DDR RAM.
The Operating System is Linux.
The Power Supply drawer is located below the MPM/
MPM+ Cards and is connected to the backplane by
means of a power connector. It operates at 100-240 volts
AC 50/60 Hz, and provides +48VDC 700W output with
built-in load sharing capabilities.
Three fans are mounted sideways in a drawer. Airflow is
from right to left, and out the side of the MCU. The drawer
is connected to the Back-plane by a connector.
The MPM cards perform the various RTP, audio and video
processing functions on the RMX 2000. MPM cards are
based on the ATCA standard, with a card manager (CM)
and up to 26 720MHz TI DSP's.
Two types are available:
•
MPM - F - 26 DSP's
•
MPM - H - 13 DSP's
The MPM+ cards, perform the various RTP, audio and
video processing functions on the RMX 2000 unit. TI
C6455 processors are at the core of each MPM+ card
which are available in the following assemblies:
MPM+20 (20 CIF resources)
•
MPM+40 (40 CIF resources)
•
MPM+80 (80 CIF resources)
Notes:
•
The MPM+ card(s) can only work with software
version 4.0. Ensure that software appropriate to the
MCU hardware configuration is installed in the MCU.
•
The MPM+ card can work only with a new
environmentally friendly D-type chassis and is
disabled when inserted in a C-type chassis.
