Start-Up of the AFU
(AFU Numbering)
It is necessary to assign an identity number to the AFU at the initial
installation or whenever master station number 1 is replaced. This
identity number automatically assigns station numbers to the analogue
devices that connect to the AFU’s extensions. The AFU is initialised
using a standard tone dialling telephone connected to extension A.
1. Plug a standard tone dialling telephone to extension A.
2. Connect the AFU BUS cable to the System bus socket. Ensure that
Master station number 1 is already installed and has been
assigned its station number (station 1).
3. Turn on the AFU plug-pack and observe the AFU LED.
The LED lights steadily for five seconds. If, after this time, it still
lights steadily, then the AFU has been previously configured..
4. Turn off the AFU plug-pack to prepare for assigning a number to
the AFU
The next four instructions (steps 5 to 8) must be completed within
the initial five seconds after power-on.
5. Turn on the AFU plug-pack.
6. Lift the handset of the telephone connected to extension A.
7. Dial [*].
8. Replace the handset.
The above four steps (steps 5 to 8) clears the AFU memory (and
the LED starts flashing). The AFU is now ready to receive its
identity number.
9. Lift the handset of the telephone connected to extension A (no
dialtone will be heard) and dial the appropriate one digit identity
number for the AFU (using the table on the next page). This assigns
the station numbers to both extension port A and extension port B.
