TA850 RCU: Convert to TDM from ATM?

[kc7gr]

Is there a way to load TDM software into a TA850 RCU, which was originally loaded with ATM software?

I just need the thing to be a simple T1 channel bank.

Thanks much!

Never mind... Answered my own question, and the answer is a firm YES! All that's needed is to update the flash with the file 850a0392.bin (I can make this available if Adtran no longer has it, and if anyone needs it).

Problem solved!
