A maintenance controller and captain report on events that contributed to an improper deferral of #1 flight warning computer (fwc-1) ECAM fault and dispatch of an A321 aircraft. Pilot notes there should be a sentence in the MEL that specifically says fwc-1 cannot be deferred; and a maintenance procedure that specifies the fwc boxes need to be switched before flight; which had not been accomplished.

Narrative:
I; maintenance controller; placed an MEL on an A321 aircraft that was in ZZZ1; but our computer systems were down and could not access the full MEL menu due to an outage from our communications provider and was not aware the flight warning computer (fwc-1) could not be meled. I did not have our air carrier's full MEL procedure to use. [Recommend] having a better back up [procedure] for computer failures.
