This book deals with structured cabling networks and specifically with their equipment and the rules based on which their design and implementation should be done. Structured cabling networks provide the required cable and related infrastructure to support a large number of applications (with computer networking being the predominant one) and their proper and rational development is both a requirement and a challenge.

More specifically, the following specific topics are examined in the book:
- The applications (weak currents) that a structured cabling network is called to support. These are:
- Classical telephony and ISDN connections (including the use of a private telephone exchange - Private Branch Exchange or PBX).
- The creation of local computer networks (Local Area Networks or LANs).
- Intercommunication.
- Surveillance and control arrangements (cameras, alarms, etc.).
- Fire detection and safety systems.
- Various control systems (e.g. air conditioning system, elevators, etc.). [...]
