LAN/intranet access only – E-LAN connection
Notes
The following notes apply to LAN/intranet access only:
•
The ICB does not interact with the Meridian system through the
E-LAN, so logically there is no requirement to put it there. In
addition, if the E-LAN is completely separated from the C-LAN, the
ICB cannot be in the E-LAN.
