[DAJ1|DAL1] Local Loop Test 

Note:

This is an on-demand test that only runs on the standby media server when it is 
busied out.

This test runs a local loop-around test on the standby media server’s [DAJ1|DAL1] board. A 
32-bit data number is written to an address and verified for correct transmission.   The test 
reads the contents of the:

●

Last data received registers

●

Last address received register

and then compares the data. If the data matches, the test passes. If not, the test fails.
The following errors can be detected:

Open failed

to MDD

ABRT

The Memory Duplication Driver (MDD) is the system driver that 

communicates with the [DAJ1|DAL1] board. If this driver cannot be 

opened, then the [DAJ1|DAL1] board’s registers cannot be read.

1. This is a system type error, try again.

System Error

MDD failed

return data

ABRT

The test ran, but, for some reason the MDD could not return data.

1. This is a system type error, try again.

FAIL

Test failed “[DAJ1|DAL1] err count query, code=?” — where “?” 

indicates which of the [DAJ1|DAL1] board’s error counters had 

positive data. The failure code can be 1–7 and is determined by the 

bit vector, “0xxx”. (Every “x” bit could be set, indicating that every 

error register had errors.) Specifically, if bit:

1 is set (0xx1) – Single-bit errors occurred.
2 is set (0x1x) – CRC errors occurred.
3 is set (01xx) – Multibit errors occurred.
