Responsibilities
The customer is responsible for providing:
•
Satisfactory lighting for installation and maintenance
•
Single-phase, correctly earthed, 240V, 10A, 50 Hz AC general-
purpose power outlets (GPO), one for every keystation and AFU.
The outlets must be easily accessible and kept clear of obstructions.
System Bus Wiring
The system is controlled by master station number 1 and requires all the
keystations (master and standard) and AFUs to be connected to the
system bus. The system bus is a simple single twisted pair cable which
is not polarity sensitive.
The system bus can be configured as:
•
A straight bus where all keystations and AFUs are “daisy chained”
from one unit to the next.
•
Star bus where all keystations and AFUs are star wired from a
central point.
For each bus configuration there are rules defining:
•
bus length
•
termination resistance
•
number of units per branch
