PIMs and BRIMs
BRIM-F6
The BRIM-F6 is an FDDI bridging device used to connect a standalone device to an FDDI network. The BRIM-F6 provides two user-configurable FPIM slots, allowing the Network Designer to specify and use any type of standard FDDI media for connection to the BRIM. The BRIM can be configured to provide either single attached or dual attached connections to the FDDI network, and can also be configured for dual-homing operation.
If the BRIM-F6 is used as a dual-attached device, the two FPIMs that are incorporated into the BRIM do not have to be of matching media. Cabletron Systems recommends that, whenever possible, the media types of each FPIM in a single BRIM-F6 match for the sake of consistency and ease of cable and connector management.
BRIM-A6
The BRIM-A6 provides a single ATM uplink for the LAN device it is placed in. The BRIM-A6 supports a variety of media types and ATM speeds and implementations. The operation and media characteristics of the ATM uplink provided by the BRIM-A6 are dependent upon the type of APIM that is placed in the BRIM’s single APIM slot. The BRIM-A6 will not operate without an APIM.
The BRIM-A6 is also available in a version incorporating a redundant connection, the BRIM-A6DP.
BRIM-W6
The BRIM-W6 supports one WAN link through a number of different WAN technologies. The BRIM-W6 provides one front panel WPIM slot, into which a WPIM module matching the functionality required of the WAN link can be placed. The BRIM-W6 will not function without a WPIM module, which determines the operational characteristics of the BRIM.
