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?
