System level maintenance
Maintenance of an IP trunk card can be performed using the following:
• overlays
• TM 3.1 PC
• the CLI of the IP trunk card
Access the IP trunk card
The IP trunk card can be accessed in two ways: by Telnet and through a
physical connection to the serial port.
Telnet access
Connect to the IP trunk card using Telnet. This provides access to the
ITG shell. A Telnet session has higher priority than a serial session. A
Telnet session started during an ongoing serial session disables the serial
connection for the period of the Telnet session. The serial session continues
when the Telnet session ends.
Serial access
Connect to the IP trunk card by physically connecting to the serial port. This
provides access to the ITG shell. If there is an active Telnet session ongoing
while the serial connection is established, the serial connection will not be
active as Telnet access has priority. The Telnet session must be terminated
in order for the serial connection to become active.
