Defining Extension Number For FT10
At the first moment
FT10
is connected to the exchange, the two-digit extension number
is displayed in the “Terminal no=aa” format. That number has been set as “11” as
factory default and it signifies the last two digits of the extension number.
If the data on the LCD display are changing upon lifting and replacing the handset, then
that indicates extension settings are correct. However, if those data are not changing,
then the extension number of FT10 must be set. In order to do that:
1) The “Park” key is pressed until the message “Terminal no=aa” appears on the
display (aa= a two-digit number – last two digits of the physical number of the
extension.)
2) One proceeds by pressing the “Park” key in short whiles until the extension number
that is desired to be set appears on the LCD display.
3) When the desired number has appeared on the display, the handset is lifted and
replaced once. From then on, FT10 will operate at that defined extension.
NOTE: When number of another extension of the exchange is entered to FT10, the
speech channel is activated; however, the data line does not function.
Number Of FT10s That Can Be Connected To The Exchange
And Connection Distances
1)
The FT10 telephones can be connected to the first 16 extensions of the exchange.
2)
Number of FT10s that will be connected to the exchange and accessories using the
external data line of the exchange should not exceed 8 in total.
The maximum number
of FT10 which will be connected to the system can be 8.
3)
If “data / 12 VDC / ground” signals and the “A / B” wires are carried to FT10 over
separate cables, then an FT10 can be located at most 250 meters far from the
exchange in the event that ordinary cables are employed.
That distance would decrease as the number of feature telephone sets that are
connected to the exchange increase. For example, when 8 FT10s are connected to the
exchange as previously explained, the maximum allowed distance between the
telephone sets and the exchange drops to 25 meters.
In such a case, if the “12 VDC” signal amplitude of the last FT10 drops below +8.5
VDC, then the performance may be improved by connecting a +12 VDC power supply
between 12VDC and ground terminals.
