Note A single 100BaseT port adapter can use either the RJ-45 (or optical ﬁber) connection or the

MII connection. If you have two port adapters on your FEIP, you can use either one of the two

connections on each port adapter, but not both connections on each port adapter simultaneously.

• Token Ring Interface Processor (TRIP)

Token Ring MAU connectors provide a direct connection between the TRIP and the ring.

• Fiber Distributed Data Interface (FDDI) Interface Processor (FIP)

Both single-mode and multimode, single and dual attachment connections are available and can

be combined on one FIP. Fiber optic cable connects directly to FIP ports using SC connectors for

single mode and MIC connectors for multimode. Single-mode uses separate transmit and receive

cables. Multimode uses one transmit/receive cable for each physical sublayer (PHY) interface.

• Optical bypass switch connector (6-pin DIN) on the Multimode/Multimode interface.

• Fast Serial Interface Processor (FSIP)

All FSIP ports support any available interface type and mode. The serial adapter cable determines

the electrical interface type and mode of the port to which it is connected. E1-G.703/G.704,

EIA/TIA-232, EIA/TIA-449, V.35, and X.21 interfaces are available in data terminal equipment

(DTE) mode with a plug at the network end and in DCE mode with a receptacle at the network

end. EIA-530 is available only in DTE mode with a plug.

• High-Speed Serial Interface (HSSI) Interface Processor (HIP)

The HIP port functions as a DTE when it is connected to a DSU for a standard HSSI connection;

it can also be connected to a collocated router with a null-modem cable. Connecting the router to

an HSSI network uses an HSSI interface cable between the HIP port and the DSU. HSSI cable

ends are identical.

• Channel Interface Processor (CIP)

The CIP has two channel adaptors, a bus and tag adapter and an ESCON adapter. The bus and

tag adapter is called a Parallel Channel Adapter (PCA), and the ESCON adapter is called an

ESCON Channel Adapter (ECA). The PCA uses 78-pin connectors for a Y cable. The ECA uses

a ﬁber optic ESCON cable with duplex connectors.

• Multichannel Interface Processor (MIP)

Two standard T1 serial cables can be used to connect the MIP: null-modem and straight-through.

These interface cables are used to connect your MIPs to additional MIPs or to external CSUs,

respectively.

You must use null-modem cables for MIP-to-MIP connections and straight-through cables for

MIP-to-CSU connections. The T1 cables used to connect the MIP with external T1 equipment

have DB-15 male connectors on each end.

Four types of E1 cable can be used to connect the MIP: BNC, Twinax, DB-15, and RJ-45. The

E1 cables used to connect the MIP with external E1 equipment have a DB-15 male connector on

the MIP end.
