FDD, which historically has been used in voice-only
applications, supports two-way radio communication by using
two distinct radio channels. Alternatively, TDD uses a
single frequency to transmit signals in both the downstream
and upstream directions.

My present SMPS ( +12V, -12V outputs, 1Amp Rating ) was faulty.I donot have similar model however i have two + 12V SMPS available. Can i use both of these SMPS as a replacement to present SMPS by connecting one of SMPS in reverese polarity.
