The station output voltages will be fine to function with 1A2 provided that the line cards are "E" models or above. 400D cards and below will not respond to ringing.

Keep in mind also that the TD1232 does not send a disconnect signal when the calling party hangs up, so calls on hold in the 1A2 will not release automatically when/if a call is abandoned.
