D.2 ETHERNET CHANNELS A, B, C, AND D

The NBR manages all Ethernet bridging traffic within its resident hub. This means that the NBR-620 controls up to four of the Ethernet bridging channels—A, B, C, and D and the NBR-220 and NBR-420 control up to two channels—A and B. These channels access the same NBR shared memory, so bridging between channels is concurrent.

D.3 CHANNELS E AND F

The NBR-420 and NBR-620 support two optional Bridge/Router Interface Modules (BRIMs). These modules provide additional connectivity and either bridging or routing functions for your NBR. At the same time, BRIMs provide access to various transmission methods (e.g., ATM, FDDI, Wide Area, etc.).

NOTE

Refer to the Customer Release Notes to see which BRIMs are supported.
