Electromagnetic interference
The CS 1000S, CS 1000M, and Meridian 1 systems meet the requirements of
FCC Part 15 and CSA C108.8 electromagnetic interference (EMI) standards
as a class “A” computing device. To accomplish this, the SDI cables must exit
the module through EMI filters on the I/O panel.
Reliability
The Mean Time Between Failure (MTBF) for all SDI cards is 55 years at
40°C and 29 years at 55°C.
Installation
To use a serial data interface card in a CS 1000S, CS 1000M, or Meridian 1
system, first install the card in the system, and then configure the system
software to recognize it. These steps are discussed in the following sections.
Instructions for cabling the serial data interface cards to the various system
consoles and peripherals are found in Communication Server 1000M and
Meridian 1: Large System Installation and Configuration (553-3021-210).
Configuring the system software
Once an SDI card has been installed in the system, the system software needs
to be configured to recognize it. This is done using the Configuration Record
program LD 17. Instructions for the Configuration Record program are found
in Software Input/Output: Administration (553-3001-311).
Maintenance
The following maintenance programs are used to maintain individual SDI
asynchronous ports. The program used depends on the application of the port.
• LD 37 Input/Output Diagnostics – Used for system terminal, printer,
background terminal ports, and system monitor status.
• LD 42 Call Detail Recording (CDR) Diagnostic – For checking CDR
links and CDR system terminals.
