I have a used Adtran 600 with 2 X Quad FXS, 2 X Dual FXS/DualX.3 and 3 X Dual FXO/Dual X3 modules. I have a Sangoma A101 Kit with RJ45 cable. Installed in my working Asterisk system is a Digium TDM22B 2 x FXS,2XFXO card. I would like to replace the Digium card with the Adtran unit, can anyone give me advice on configuration, I have no experience with the Adtran unit.
