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.
• Nortel Networks recommends that customer try not to put any BUI
traffic on the E-LAN if possible.
• Each site should select the most convenient option, taking into
account the physical LAN endpoints available near the ICB card.

traffic only
1. The ICB is not open to Customer LAN (C-LAN) traffic and you can block traffic through the router
(for example, Telnet and FTP).
2. The ICB BUI traffic is on the Embedded LAN (E-LAN).
3. If there is no router between the C-LAN ad the E-LAN, there is no BUI access from the C-LAN.
