Backplane Interface - Avaya Nortel Communication Server 1000 Reference

Backplane interface

The FPGA features include:
• Serial data interface port
• Time slot interchanger (TSIC)
• SSD X12/A10 signaling interface
• CE-Mux bus interface
• CardLan interface
• DS30x interface
• TDM bus for tones and conference
• System clock generation and system clock reference
Serial data interface ports
The MGC has three serial data interface (SDI) ports. The ports can be used locally for
debugging, or they can be configured in the CS 1000E Call Sever as system terminals. Only
ports SDI 0 and SDI 1 can be used to access the installation menu during initial configuration
of the MGC. SDI 2 is not available during bootup. Due to a limitation of the three port cable
used, SDI 1 and SDI 2 do not use hardware flow control. Only SDI 0 has full modem
support.
TTY default settings
The default tty settings for the SDI ports are:
• Baud rate: 9600.
• Data bit length: 8.
• Stop bit: 1.
• Parity: none.
• Flow control: none.
MGC serial port configuration change
If the serial ports are configured as SL1 terminals on the Call Server, the tty default settings
can be changed in LD 17. Any values configured in LD 17 are downloaded to the MGC and
