Electrostatic discharge
The SDI cards meet the requirements of the IEC 801-2, clause 8.0
procedure. They can withstand a direct discharge of ±5 to ±20 kV without
being damaged.
Electromagnetic interference
The CS 1000E, 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 1000E, 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 (NN43021-310).
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 Reference — Administration
(NN43001-611).
