Functional Description 

1-7 

On power-up, both the local and remote MBE10-8s will connect to their 
respective LANs. The remote MBE10-8 continuously learns the addresses of 
workstations on the remote LAN and updates the local MBE10-8 with these 
addresses (up to 80 addresses). 
The remote MBE10-8 forwards all frames to the local LAN that are not addressed 

to workstations on the remote LAN. The local MBE10-8 forwards all frames that 
have destination addresses belonging to one of the remote workstations to the link. 
Broadcast and multicast packets are always forwarded in both directions, unless 
they are masked out using the filtering tool (see the 

). 

Operational characteristics of MBE10-8D are identical, in most respects, to those 
of MBE10-8, except that MBE10-8D (located at the local LAN) supports 
connection of two remote LANs (one per link).  
MBE10-8D supports up to 80 addresses per LAN providing a total of 160. 
Broadcast and multicast packets are always forwarded in both directions, unless 
masked out using the filtering tool (see the 

). MBE10-8D can also be installed on a remote LAN where one link serves as 

a backup link to the other.
