The Charlie Answer:

LEC:  edge device such as a router with ATM interface.
LES:  registers clients and keeps a database of clients who have registered.
1 per ELAN.
BUS:  handles broadcasts, multicasts and "unknown" casts!!!   1 per ELAN.
LECS:  tells LEC what LES to use.    1 per administrative domain (analogous
to an AS).
