That is correct; the DS3000P will support full access to every channel 
on the DS-3 (or E-3), however it is provisioned. In a T1-RBS signaling 
mode, that means 672 voice channels. In a T1-PRI signaling mode, it 
could be as many as 670 or as few as 644, depending on how many 
D-channels are provisioned.

The same logic applies to E-3 mode: since an E-3 is the equivalent of 16 
E-1, the channel capacity will vary from 496 to 480, depending on 
signaling mode.
