ITG HEX display Codes
The NTDW65 MC32S Media Card provides 32 IP-TDM gateway ports. It replaces the previous ITG (Integrated IP Telephony Gateway Trunk) cards and runs on CS 1000 Release 5.0 software. The four-digit faceplate display indicates card status or a fault condition.
Replace the Media Card when (after a reboot) a fault is displayed in the form F:xx on the faceplate display as this indicates an unrecoverable hardware failure. Note, if the Media Card displays F:08, this can just mean that the Security Device is missing.
If a test fails, F:XX shows on the hex display for three seconds after the T:13 (Testing SEEPROM) message, with the number represented by XX indicating the test that failed. For example, if the 8051 co-processor test failed, F:05 shows.
|T:01||Testing internal RAM|
|T:03||Testing address modes|
|T:05||Testing 8051 co-processor|
|T:07||Testing external RAM|
|T:08||Testing dongle (F:08 may mean the security device is missing or bad)|
|T:09||Programming timeswitch FPGA|
|T:10||Programming ISPDI FPGA|
|T:11||Testing host dual port RAM|
|T:12||Testing DS-30 dual port RAM|
|T:14||Booting Host processor, waiting for response with selftest information|
|T:20||Waiting for application start-up message from Host processor|
|T:21||CardLAN enabled, waiting for request configuration message|
|T:22||CardLAN operational, A07 enabled, display now under host control|
If the internal RAM test, ALU test, address mode test, boot ROM test, timer test, or external RAM test fails, the pack goes into a maintenance loop as no further processing is possible.
If the IXP encounters any failures during its initialization, an H:XX error code displays. The list of error codes is as follows:
|H:00||Host Processor not booting|
|H:01||SDRAM test failure|
|H:02||SRAM test failure|
|H:04||PCMCIA device failure||H:08||Network interface failure|
|H:10||Meridian 1 interface failure|
|H:20||DSP interface failure|
|H:40||NVRAM/EEPROM interface failure|
|H:80||PCM connector failure|
If the hardware selftests pass and the application starts up successfully, the screen cycles through the following display codes to indicate the function and status of the card.
|LDR/BLDR/FLR||Pack role: leader/backup-leader/follower|
