ITG HEX display Codes
The NTDW65 MC32S Media Card provides 32 IP-TDM gateway ports (DSP's). It replaces the previous ITG (Integrated IP Telephony Gateway Trunk) cards and runs on CS 1000 Release 5.0 software. The four-character LED 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.
Maintenance Codes
If a test fails, the T:XX code will change to F:XX for three seconds, where XX indicates the test number. For example, if the 8051 co-processor test fails, T:05 → F:05 is displayed.
Display | Description |
---|---|
T:00 | Initialisation |
T:01 | Testing internal RAM |
T:02 | Testing ALU |
T:03 | Testing address modes |
T:04 | Testing watchdog |
T:05 | Testing 8051 co-processor |
T:06 | Testing timers |
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:13 | Testing SEEPROM |
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.
Error Codes
If the IXP encounters any failures during its initialization, an H:XX error code displays. The list of error codes is as follows:
Display | Description |
---|---|
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 |
Status Codes
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.
