Informacijska tehnologija - Univerzalni sistemi polaganja kablov - 1. del: Splošne zahteve
Ta evropski standard določa:
a) strukturo in konfiguracijo hrbteničnih podsistemov polaganja kablov v univerzalnih sistemih za polaganje kablov znotraj tipov prostorov, ki so določeni z drugimi standardi serije EN 50173; b) delovne zahteve kanalov v podporo standardom serije EN 50173; c) delovne zahteve zvez v podporo standardom serije EN 50173; d) referenčna izvedba hrbteničnega polaganja kablov v podporo standardom serije EN 150173; e) delovne zahteve komponent v podporo standardom serije EN 50173.Varnostne zahteve (električna varnost in zaščita, optična moč, ogenj itd.) in zahteve elektromagnetne združljivosti (EMC) so zunaj področja tega evropskega standarda in so zajete z drugimi standardi in predpisi. Vendar so lahko informacije, podane v tem evropskem standardu, v pomoč pri izpolnjevanju teh standardov in predpisov.

the far-end
NOTE This also applies to the measurement of the signal isolation between a disturbing pair within a permanent link or component,
used to create a channel, and a disturbed pair within a permanent link or component, used to create another channel.
3.1.4
alien (exogenous) near-end crosstalk loss (ANEXT)
signal isolation between a disturbing pair of a channel and a disturbed pair of another channel, measured at
the near-end
NOTE This also applies to the measurement of the signal isolation between a disturbing pair within a permanent link or component,
used to create a channel, and a disturbed pair within a permanent link or component, used to create another channel.
Renumber existing definition 3.1.2 into 3.1.5.
3.1.6
attenuation to alien (exogenous) crosstalk ratio at the far-end (AACR-F)
difference, in dB, between the alien far-end crosstalk loss from a disturbing pair of a channel and the
insertion loss of a disturbed pair in another channel
NOTE This also applies to the calculation using the alien far-end crosstalk loss from a disturbing pair within a permanent link or
component, used to create a channel, and the insertion loss of a disturbed pair within a permanent link or component, used to create
another channel.
3.1.7
attenuation to alien (exogenous) crosstalk ratio at the near-end (AACR-N)
difference, in dB, between the alien near-end crosstalk loss from a disturbing pair of a channel and the
insertion loss of a disturbed pair in another channel
NOTE This also applies to the calculation using the alien near-end crosstalk loss from a disturbing pair within a permanent link or
component, used to create a channel, and the insertion loss of a disturbed pair within a permanent link or component, used to create
another channel.
3.1.8
attenuation to crosstalk ratio at the far-end (ACR-F)
difference, in dB, between the far-end crosstalk loss from a disturbing pair of a channel and the insertion loss
of a disturbed pair of the same channel
NOTE This also applies to the calculation using the far-end crosstalk loss from a disturbing pair within a permanent link or
component, used to create a channel, and the insertion loss of a disturbed pair within the permanent link or component, of the same
channel.
3.1.9
attenuation to crosstalk ratio at the near-end (ACR-N)
difference, in dB, between the near-end crosstalk loss from a disturbing pair of a channel and the insertion
loss of a disturbed pair of the same channel
NOTE This also applies to the calculation using the near-end crosstalk loss from a disturbing pair within a permanent link or
component, used to create a channel, and the insertion loss of a disturbed pair within the permanent link or component, of the same
channel.
3.1.10
average alien (exogenous) near-end crosstalk loss
calculated average of the alien near-end crosstalk loss of the pairs of a disturbed channel
NOTE This also applies to the calculation using the pairs within a permanent link, used to create a channel.
3.1.11
average power sum alien (exogenous) near-end crosstalk loss
calculated average of the power sum alien near-end crosstalk loss of the pairs of a disturbed channel
NOTE This also applies to the calculation using the pairs within a permanent link used to create a channel.
3.1.12
average power sum attenuation to alien (exogenous) crosstalk ratio far-end
calculated average of the power sum attenuation to alien crosstalk ratio at the far-end of the pairs of a
disturbed channel
NOTE This also applies to the calculation using the pairs within a permanent link used to create a channel.
Renumber existing definitions 3.1.3 to 3.1.46 into 3.1.13 to 3.1.56.
Replace definition 3.1.7 (renumbered 3.1.17) by:
3.1.17
building entrance facility
space that provides all necessary mechanical and electrical services for the entry of cables into a building
Replace definition 3.1.26 (renumbered 3.1.36) by:
3.1.36
external network interface
termination point providing external network demarcation
Add the following definitions and renumber the existing definitions 3.1.47 to 3.1.56 into 3.1.63 to 3.1.72 :
3.1.57
power sum alien (exogenous) far-end crosstalk loss (PSAFEXT)
power sum of the signal isolation between multiple disturbing pairs of one or more channels and a disturbed
pair of another channel, measured at the far-end
NOTE This also applies to the calculation using the multiple disturbing pairs within one or more permanent links or components and
a disturbed pair within a permanent link or component, used to create another channel.
