I will post the same reply here as the other thread:
Ok, when you have different number of speech that is not div by 4, then it requires an extra virtual board due to underlying firmware confirmation loaded for those channels. So if you run devmapdump from DOS prompt I bet it will show the following:
dxxxB1C1 (has FEP address for CSP component)
dxxxB1C2 (has FEP address for CSP component)
voice only
dxxxB2C1
dxxxB2C2
