This is an old message, but it does highlight a limitation of Cisco's ELAN
configuration....
The .** in the addresses (selector) is actually the ELAN number in hex, as
such, only 255 ELAN's can be supported on the one LECS pair..... ( There is
no ELAN 0, and the LECS forces this to 00 anyway ).
Does anyone know if this is the only way that ELAN's can be implemented on
Cisco kit, or can this "default" numbering plan be overridden ? ie Cisco's
use of the selector and last nibble of the ESI ?
