Actually there is no difference in the l2circuits persay, what the -B card 
adds is the ability to do vlan-ccc encapsulation. This is commonly USED on 
l2circuit terminations (or regular ccc for that matter), so you can run it 
to a subinterface and do multiple l2circuits (or mixed l2circuits and 
regular L3 routing, etc) on a single physical interface. You can always do 
l2circuits to an untagged GE interface on any rev card.

Only the single-port GE-SX cards were ever produced without this 
functionality, so if it isn't a P[EB]-1GE-SX it is automatically equiv to 
the GE-SX-B (LX, LH, 2GE, 4GE, etc).
