1. The MICB is not open to Customer LAN (CLAN) tr affic and you can block traffic through the router
(for example, Telnet and FTP).
2. The MICB BUI traffic is on the Embedded LAN (ELAN).
3. If there is no router between the CLAN ad the ELAN, there is no B UI access from the CLAN.
Notes
The following notes apply to LAN/intranet access only:

Meridian Integrated Conference Bridge
World Wide Web
Firewall
Router
The MICB does not interact with the 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 MICB 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 MICB card.
