Media Card 32-port trunk card faceplate maintenance display codes 421
Socket Services are responsible for card insertion and removal. There is
a single interruption shared for insertion and removal events and a single
interruption for device-specific interruptions. Socket Services identify which
socket originates the interruption and sends the interruption to the Card
Services interruption handler. Card Services then wait and re-initialize the
PC Card, if the card is plugged in again and is in the READY state.
Do not insert or remove the PC Card when the IP trunk card is plugged in.
DCHIP card failure
This occurs when the DCHIP IP trunk card goes out of service. The DCHIP
IP trunk card failure case is similar to the DCH link failure case. However,
all call reference information is gone. As a result, when the DCHIP comes
back up, it sends a "REStart" message to the other side to re-initialize all the
trunks. All the established calls are terminated.
Power loss
Since the IP trunk card is based on Flash EPROM technology, all
configuration data is preserved for 10 years. There is no requirement for a
battery backup for the card. The IP trunk card can be removed from the IPE
shelf indefinitely and still retain all configuration data.
Media Card 32-port trunk card faceplate maintenance display codes
The maintenance display of the Media Card 32-port tr unk card provides
startup codes, operating mode and error information on the functional card
state. Table 68 "Media Card 32-port trunk card faceplate maintenance
display message summary" (page 422) lists the startup codes and operating
mode codes.
When the Media Card 32-port trunk card starts up, it performs multiple
self-tests. The faceplate display shows the test results.
If the internal RAM test, ALU test, address mode test, boot ROM test,
timer test, or external RAM test fails (T:00 - T:07), the pack goes into a
maintenance loop as no further processing is possible. If a test fails, F:XX
shows on the hex display for three seconds after the T:13 message, with
the number represented by XX indicating the test that failed. For example,
if the 8051 co-processor failed, F:05 displays. If more than one test fails,
the message displayed indicates the first failure.
