2.2 Kilostream Interface Characteristics
The Kilostream service provided in the United Kingdom is a full duplex
leased 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 of
these electrical variants, through the same 15-pin D-type connector. The
option required is controlled by plug-in links on the main circuit board of
the unit.
The link settings for both the ‘USER’ and ‘LINK’ connectors must be set
to reflect the electrical interface characteristics supplied on the data link
in which they sit. For example: If the link between your channel 1 NTU
and the user equipment requires a V35 option then the connectors USER
1 and LINK 1 must have their links set to V35.
