T1 is *24* 64K channels. E1 is *32* 64K channels.
On a T1 all 24 are used for data and signalling is inband, cutting it to
24 56K data channels. On T1 PRI one channel is used for signalling leaving
23 64K channels.
On E1 2 channels are used for signalling either way, and you have 30 64K
data channels.
Note these are for channelized circuits/PRI. Used as a straight leased line
it is one big pipe.
T1 is 1536K plus 8K signalling for 1544K.
E1 is 2048K.

I'd use 4 10s and an 8 - same cost, and it leaves a slot open. yes we have
other cards planned for the chassis.
