D.1 NBR OVERVIEW
The NBR provides bridging and management for up to four separate
Ethernet channels (A, B, C, and D). The following list contains the
currently available EPIMs:
• EPIM-T – 10BASE-T Twisted Pair Segment Interface Module
• EPIM-F1/EPIM-F2 – Multimode Fiber Optic Segment Interface
Modules
• EPIM-F3 – Single Mode Fiber Optic Segment Interface Module
• EPIM-C – Thin-net Coaxial Interface Module
• EPIM-A/EPIM-X – AUI Cable Segment Interface Modules
In addition to Ethernet channels A through D, the NBR provides
management for two optional Bridge/Router Interface Modules (BRIMs).
These modules allow for additional Ethernet connections, Wide Area
(Full or Fractional T1; 56 k DDS) access, or links to existing high-speed
Asynchronous Transfer Mode (ATM) or Fiber Distributed Data Interface
(FDDI) network backbones.
NOTE
Refer to the Customer Release Notes to see which BRIMs are
supported.
