ITG Line card 2.0 maintenance
Solutions
Case 1: If a SIMM is missing, install a 16MB SIMM into the SIMM slot
which is found underneath the ITG daugherboard. If the SIMM is present,
check that the SIMM is properly seated. Otherwise, the SIMM is faulty and
needs replacement.
Case 2: Re-attempt a software download from the MAT/OTM host. Use the
following commands:
upgradeErase
upgrade "hostname","hostAccount","hostPassword",
"hostDirectoryPath","hostSWFilename"
After the software loads to flash, reboot the card:
sysReboot
If the failure to load the ITG software into RAM persists, then the flash device
is faulty. Replace the ITG Line 2.0 card.
Case 3: The escape sequence "xxx" is rarely transmitted. Reboot the card.
The following ITG shell command performs a warm reboot of an
out-of-service ITG Line 2.0 card:
At the ITG shell, the following two tests can be performed on the ITG DSPs:

Note: If the DSP self test fails, the ITG Line 2.0 card must be replaced.
• To run a PCM loopback test, a Send loopback test, or a Receive loopback
test on the DSP daughterboard, respectively:
DSPPcmLpbkTestOn
DSPSndLpbkTestOn
DSPRcvLpbkTestOn
Note: The DSPs and all associated ports must be disabled before
performing these tests.
