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
Telnetsession started dur ing an ongoing serial session disables the serial
connection forthe per iod of the Telnetsession. The serial sessioncontinues
when the Telnetsession 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 Telnetsession ongoing
while the serial connection is established, the serial connection will not be
active as Telnetaccess has priority. The Telnet session must be terminated
in order for the serial connection to become active.
IP trunk card LD commands
System level maintenance of the IP trunk card is performed using LD 32 or
LD 36. See Table 56 "Supported LD 32 commands" (page 397) and Tab le
57 "Supported LD 36 commands" (page 397).
