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.

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.
