The power supply for the Thunderbolt should not be a showstopper.  The manual spec states that
the board needs +12vdc @ 750ma max and -12vdc @ 10ma with ripple at 75mV P-P. The rest of the board needs +5vdc @ 400ma with ripple a spec of 50mV P-P, which is a mid quality power supply. Lab supplies are usually < 5mV P-P, with cheap switchers above 100mV P-P. The reason that most telco units have DC converters is the use of 48vdc power common in that industry.
