S 2.20 Monitoring of existing connections
Initiation responsibility: Head of Site/Bldg Technical Service, Head of
IT Section
Implementation responsibility: Head of Site/Bldg Technical Service; network
planner
A visual inspection (at least on a random basis) must be made of all
distributors and duct boxes. Attention must be paid to the following aspects:
- traces of attempts to open locked distributors by force;
- up-to-date information provided in the documentation placed in the
distributors;
- correspondence of actual line assignments and strap connections with the
information provided in the documentation;
- integrity of the short-circuits and grounding of non-required circuits; and
- inadmissible installations/modifications.
A functional check can be made in addition to the mere sight check. For this
purpose, existing lines will be reviewed for their necessity and for compliance
with technical parameters. Such a review is advisable in the following
situations:
- in the case of lines which are very seldom used and where manipulations
are not detected at once;
- in the case of lines over which sensitive information is transmitted
frequently and regularly.
Additional controls:
- At what intervals are existing connections being checked?
- How are identified irregularities documented and followed up?
- To whom must such irregularities be reported?
- Who will remedy any irregularities, and who will monitor such work?
