Locating the LECS, LES, and BUS services
An ATM network may contain several ELANs. The network must only have one 
LECS, and each ELAN must have one active LES and one BUS (which may be part 
of a distributed LES/BUS).
The LECS, LES, and BUS constitute the LANE Services. These elements must reside 
on hosts that all the LECs on a network can access. They can be located on the same 
host or on different hosts, which may be one of the following:
An  ATM  switch
A dedicated workstation
An existing or dedicated server. For example, the services could be 
implemented as NetWare Loadable Modules (NLMs) on a NetWare server.
