Note Cisco Systems announced the end-of-sale and end-of-life dates for the Cisco ONS 15454 MSPP
Universal BackPlane Interface Adapter, Vertical Orientation (UBIC-V), and its DS1 and DS3 Cables.
For further details, refer to Product Bulletin No. EOL5039 at

The UBIC-V EIA is designed to support DS-1, DS-3, or EC- 1 signals. The type of signal supported is
determined by the respective UBIC-V cable assembly.
DS-1 cables for the UBIC-V have a maximum supported distance of 655 feet (199.6 m). DS-1 cables
arrive with unterminated #24 AWG twisted pairs on the far end and are color coded as identified in
Table 1-17.
The following DS-1 cables are no longer available from Cisco Systems for use with the UBIC-V EIA:
• DS-1 cable, 150 feet: 15454-CADS1-SD
• DS-1 cable, 250 feet: 15454-CADS1-ID
• DS-1 cable, 655 feet: 15454-CADS1-LD
DS-3/EC-1 cables for the UBIC-V have a maximum supported distance of 450 feet (137.2 m).
DS-3/EC-1 cables arrive with unterminated coaxial cable at the far end and labeled with the respective
port number. 75-ohm BNC connectors for each port (qty. 12) are supplied and require that they be
crimped on.
The following DS-3/EC-1 cables are no longer available from Cisco Systems for use with the UBIC-V
EIA:
• DS-3/EC-1 cable, 75 feet: 15454-CADS3-SD
• DS-3/EC-1 cable, 225 feet: 15454-CADS3-ID
• DS-3/EC-1 cable, 450 feet: 15454-CADS3-LD
Figure 1-23 identifies the pin numbers for the DS-1 and DS-3/EC-1 cab les as referenced from the SCSI
connector.
Figure 1-23 Cable Connector Pins
Table 1-16 identifies the UBIC-V SCSI connector pin assignments for the DS-1 cables as referenced
from the EIA backplane to the SCSI connector.
Note Conversion from the back plane’s single ended (unbalanced) 75-ohm signal to a differential (balanced)
100-ohm signal happens through the embedded transformer within the SCSI connector. The cable's
shield is connected to the connector shell. This conversion is illustrated in Figure 1-24.
