TRACE and ALARM/LOG

Call Tracing (TRACEFile Command)

This command interfaces with all modules to create an efficient TRACE File.
It is a monitor that stores and keeps track of information about events. For
all error conditions, a clear log of all actions is available. The TRACE File
does not solve these errors; it only indicates that there were errors and
shows where the errors originated. The TRACE File asks each module to
report all events and records the errors in order in a complete eventlog.
Each event is marked with a severityindicator.

LOG File

All hardware alarms, normal log messages, and severe events are logged
in a single LOG file.
ITG shell command set
ITG shell commands are designed to supplement overlaycommands and to
introduce new features specific to IP Trunk3.01 (and later).
Toaccess ITG shell commands, connect an TM 3.1 PC or a TTY to the
RS-232 Maintenance port on the IP trunk card faceplate. Alternatively,
connect the TM 3.1 PC or a TTY to the Serial I/O Panel port to create a
more permanent connection to the IP trunk card maintenance port.
CAUTION
Neverconnect to the front and back serial por ts at the same time.
All ITG shell commands are case-sensitive.
Commands are grouped into eight categories, as shown in Tabl e 61
"General purpose commands" (page 401) Table 66 "DCHIP-only
