[Asterisk-Users] Is it mandatory to give power supply to TDM400Pcard

[Rich Adamson]

BS! Fxo modules do "not" require the power connector, period. The connector
is only used to develop ringing voltage for fxs modules. It's very easy to
trace the power connector wiring and find that it goes nowhere when fxo modules
are used.
