Media Card 32-port trunk card faceplate maintenance display codes 423

Socket Services are responsible for card insertion and removal. There is

a single interruption shared for insertion and removal eventsand 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 READYstate.

Do not insert or remove the PC Card when the IPtr unk cardis plugged in.

This occurs when the DCHIP IP trunk card goes out of service. The DCHIP

IP trunk card failure case is similar to the DCH linkfailure case. However,

all call reference information is gone. As a result, when the DCHIP comes

back up,it sends a "REStar t" message to the other side to re-initialize all the

trunks. All the established calls are terminated.

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 trunk card provides

startup codes, operating mode and error information on the functional card

state. Table68 "Media Card 32-por t trunk card faceplate maintenance

displaymessage summary"(page 424) lists the star tup 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 forthree 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.

If the hardware self-tests pass and the application starts up successfully,

the screen cycles through the display codes to indicate the function and

status of the card
