PIMs and BRIMs
4-4 Port Interface Modules
TPIMs
TPIMs are Token Ring Port Interface Modules. A TPIM provides a single Token
Ring connection. If the Token Ring device the TPIM has been placed in allows it,
the TPIM connection can be used as either a station port or a RI/RO port. All
TPIMs use active Token Ring circuitry. The available TPIMs and the connectors
and media they support are listed below:
TPIM-F2: Multimode Fiber Optics (ST Connectors)
TPIM-F3: Single Mode Fiber Optics (ST Connectors)
TPIM-T1: Shielded Twisted Pair (DB9 Connector)
TPIM-T2: Unshielded Twisted Pair (RJ45 Connector)
TPIM-T4: Shielded Twisted Pair (RJ45 Connector)
FPIMs
FPIM stands for FDDI Port Interface Module. The FPIM is a single link for
connection to a single cable in an FDDI network. The operation of an FPIM (what
type of FDDI port it behaves as) is determined by the FPIM slot it is inserted into.
The FPIMs available and their supported media are listed below:
FPIM-00: Multimode Fiber Optics (MIC Connector)
FPIM-01: Multimode Fiber Optics (SC Connector)
FPIM-02: Unshielded Twisted Pair (RJ45 Connector)
FPIM-04: Shielded Twisted Pair (RJ45 Connector)
FPIM-05: Single Mode Fiber Optics (MIC Connector)
FPIM-07: Single Mode Fiber Optics (SC Connector)
