Doktor,
This is from my memory, but should be approx. right:
Each ELU29 in the LIM "eats" about 10W, when normal speech/idle (10 boards)
Each ELU28 in the LIM "eats" about 3W, when normal speech/idle (20 boards)
TMU, TLU , LSU etc. e"eat" tigether about 20-30W (3 sets)
Each DBC 213 in the LIM "eats" about 1W, when normal speech/idle (320 phones)
This is the power dissipation, so you need to calculate the rest yourself, but putting everything together here is about 500W.
I suppose this info can be found in Alex, Dynatext, DocView or whatever.....
