BusinessPhone Communication Platform 7.0
System Description ASB 150 02

## Installation

ASB 150 02 is easy to install and no special know-ledge of the system is required. 1-3 cabinets, depending on system size, are mounted on a wall. The control system, a printed board assembly, is placed in the first cabinet. The device boards can then be placed in arbitrary board positions. The system boards can be replaced by boards of the same type and configuration while the system is in operation. The cabinets are interconnected via a prefabricated ribbon cable. Each cabinet is furnished with its own current feed, a transformer or a charging rectifier with battery.

Prefabricated connection cables are available for connecting the device boards to an internal or external MDF.

The line network for the extensions is installed according to normal rules for telephone networks. For the digital system telephones it is necessary to utilise twisted pair cable with 0.5 mm diameter. The line length can be a maximum of 800 metres.

Note

No unterminated stubs and/or branches may exist on a digital extension line as they would cause disturbances.

On addition or replacement of boards, the system must be shut down and then be restarted.

The hardware, i.e. boards, is designed to be replaced without switching off the power supply, but at present there is no program support for this function.

For details, consult the relevant installation documents.
