Foreword
This European Telecommunication Standard (ETS) has been produced by the Equipment Engineering
(EE) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 4 of a 4 part ETS aimed at setting out, on a common basis, the engineering requirements
for telecommunication practice, for housing equipment forming part of a public telecommunications
network. Part 1 is a general introduction and explains the terminology used, Part 2 specifies the
engineering requirements for racks and cabinets and Part 3 specifies the engineering requirements for
miscellaneous racks and cabinets. This part, Part 4, specifies the engineering requirements for subracks
mounted in miscellaneous racks and cabinets.
This ETS applies to all telecommunications equipment forming part of the public telecommunications
network. The requirements for subracks mounted in miscellaneous racks/cabinets, which this part lays
down, are based on the work of IEC Technical Committee 48D. However, in this part of the ETS deviation
from the work of IEC Sub Committee 48D occurs (see Annex B).
Illustrative figures are contained in Annex A.

1 Scope
This part of European Telecommunication Standard (ETS) 300 119 details requirements for subracks for
use in miscellaneous racks/cabinets, as described in ETS 300 119-3 [4]. The subrack will normally be
supplied as a fully assembled structure, unequipped, partially equipped or fully equipped with plug-in units,
etc.
