S 1.22 Physical protection of lines and distributors
Initiation responsibility: Network planner; Head of Site/Bldg
Technical Service; Head of IT Section
Implementation responsibility: Site/Bldg Technical Service
In rooms visited by the general public or in building areas which can not
easily be overseen, it may be expedient to protect lines and distributors. This
can be accomplished in different ways:
- concealed wiring of lines;
- steel-armoured conduits for lines;
- running lines in mechanically solid and lockable ducts;
- locking of distributors; and
- if required, additional electrical monitoring of distributors and ducts.
In case of locking, arrangements must be made which lay down the access
rights, the distribution of keys and the access modalities (what must the
authorised person possibly do before having access to lines?).
Additional controls:
- Have the number of places providing access to the cable been minimised?
- Has the length of routes requiring protection been kept as short as possible?
- Are access rights granted restrictively? Is account taken of staff turnover
and substitution?
- Are access rights being regularly reviewed for authorisation/necessity?
