Cabling Summary
The connectors on the UFI cards are high density. Each UFI-12V.35 and UFI-12X.21 card has six 60-pin
connectors. Each of these connectors has two ports. If your specification dictates that both ports on a
connector are active, you must have a cable with wiring for two ports. If a part number in Table A-26
has the form “CAB-2...,” the cable has wiring for two ports. Note that if both ports on a connector are
active, both ports must be either DCE or DTE, because the cable itself is either DCE or DTE. If a
connector has only one active port, the cable can be the less expensive, single-port version. An HSSI
connector has 50 pins and supports one port.
Port redundancy through the use of a Y-cable requires two card sets, at least one Y-cable, and the
standard cabling. On a UFI-4HSSI, Port 1 is the only port that supports Y-cable redundancy. On the V.35
and X.21 UFIs, redundancy at more than one connector requires a corresponding number of Y-cables
and standard cables. The standard cables are either single-port for HSSI, V.35, or X.21 or dual-port for
the X.21 and V.35 UFIs.
To set up the Y-cabling, you attach a branch of the Y at the primary and redundant connectors then attach
the near end of the standard cable to the base of the Y. Figure A-3 illustrates single and dual-cabling in
a Y-cable setup. The single-cable arrangement applies to HSSI, V.35, and X.21. The dual-port
redundancy setup applies to a UFI-12X.21 or UFI-12V.35, where both ports within the UFI connector
are used in a Y-cable redundancy scheme.
