Analogue Trunk Card not being recognised

[Olisa]

I moved my ATM16 analogue trunk (with v6.2) from my IP412 (with v4.2) to an old IP406v1 (with v3.2) to test something. The card was not automatically detected by the 406v1. I now returned it back to the 412 but it is now not being recognized.

I have rebooted both the card and the 412 but no detection.

Pls help me out? what could be wrong?

Olisa,

please turn is all off.

connect the module while disconnected!!!! TDM is pretty sensitive!

turn the ATM module on first! let the light go green.

turn on the 412. let light go green.

does the ATM light go solid green after that?

i would be inclinded to try a different expansion port if the above doesnt work.
