MD110 Console issues

[Ozphonebloke]

Hi All,

I am an Ericsson novice working with MD110s and other PABXs restoring them in a collection/museum.

One of our MD110s has some odd things happening with the console - e.g. cannot turn off loud horn for incoming traffic.

Tried swapping keyboards on the console and then tried swapping entire consoles but same fault.

Have tried restarting the board (ELU5) using RFBOI

Have tried to restart program units for console but only one worked (OLP1D) tried to restart OPS1S1 but it was not accepted (unreasonable value unit)

Any other suggestions for program units to be restarted etc to get the console back to healthy operation?

Thank you,

quick update - restarting some program units and the card via FIOL did assist. there is now two way speech (which was one of the faults) but the last fault is I cannot use the PC button on the console to toggle between the ring settings (i.e. short burst and long loud tone).
