FDDI Optical Bypass Switch Signals
FDDI Optical Bypass Switch Signals
Table A-7 lists the signal descriptions for the mini-DIN optical bypass switch available on the
multimode/multimode FIP (Cx-FIP-MM) and the single-mode/single-mode (CX-FIP-SS) FIP. The
mini-DIN-to-DIN adapter cable (CAB-FMDD) allows connection to an optical bypass switch that
uses a DIN connector (which is larger than the mini-DIN connector on the FIP).
Table A-7 Optical Bypass Switch Pinout
Serial Adapter Cable Pinouts
The FSIP supports EIA/TIA-232, EIA/TIA-449, X.21, V.35, and EIA-530 serial interfaces.
All FSIP ports use a universal port adapter, which is a 60-pin receptacle that supports all available
interface types. (The exception to this is the E1-G.703/G.704 port adapter, which uses a DB-15
connector.) A special serial adapter cable, which is required for each port, determines the electrical
interface type and mode of the interface. The router (FSIP) end of all of the adapter cables is a 60-pin
plug; the connectors at the network end are the standard connectors used for the respective
interfaces.
All interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector
at the network end and DCE with a receptacle at the network end. V.35 is available in either mode
with either gender at the network end. EIA-530 is available in DTE only.
The tables that follow list the signal pinouts for both the DTE and DCE mode serial port adapter
cables for each FSIP interface type.
Pin Description

3 Ground to enable primary switch
4 Ground to enable secondary switch
