A (conceptual) table utilized by a LECS to map a
registered MAC address of a LEC to an ELAN name. This
table is used be the LECS to assign a LEC to an ELAN.
It is, however, not mandatory for all configurable
LECs to be in this table as they may opt to use the
lecsAtmAddrConfigTable instead or perhaps rely on the
default ELAN set in the lecsConfigTblTable. Also note
that a LES may opt to use this table to determine
authorization of a LEC to join an ELAN.
