From the manual it says;
A28 Automatic diagnostic test. Console has failed a
loop-back test.
Check console wiring.
Replace console.
If problem persists, replace Control Card.

Good Luck!

That is what I thought. Its also strange that the console is unable to dial speed dials and that other extensions can. Thanks.
