Gevaarlijke voltages.2.2 Kilostream Interface CharacteristicsThe Kilostream service provided in the United Kingdom is a full duplexleased line, with X21 or X21bis customer interface.NOTE: ‘Kilostream’ is a generic term, referring to any X21 or X21bis non-switched service.X21 and X21bis include V11, V35 and V24 as electrical interface options.Your KBU 64 has been designed to enable compatibility with any ofthese electrical variants, through the same 15-pin D-type connector. Theoption required is controlled by plug-in links on the main circuit board ofthe unit.The link settings for both the ‘USER’ and ‘LINK’ connectors must be setto reflect the electrical interface characteristics supplied on the data linkin which they sit. For example: If the link between your channel 1 NTUand the user equipment requires a V35 option then the connectors USER1 and LINK 1 must have their links set to V35.
