A (conceptual) table utilized by a LECS to map a
registered Route Descriptor of a LEC to an ELAN name.
This table is used by 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 or
lecsMacConfigTable 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.
