• IP of the router
Press the SEL key to save this data.
It may happen that not all computers in a network will always respond
within the query time of the test device, as they may be occupied with
other tasks. This is due to the system-specic nature and does not rep-
resent an error. The query can be repeated as often as desired.
The subscriber list is opened with ESC. By selecting a subscriber, the IP and MAC address are
displayed in addition to the Name, the IP Address, and the MAC Address. This address can
then be pinged in this menu.
Selecting with SEL opens the Ping menu. The frame size is displayed in the upper left corner.
The ▲ and ▼ keys can be used to set the frame size between 32 and 1024 bytes.
Start of the ping test with SEL.
The KE7200 now continuously sends pings to the
selected address. This is done at maximum speed in
order to perform a stress test for all components at the
same time.
It may happen that the network compo-
nent is overloaded by the ping stress test
and stops responding.
The success of the test is indicated by the number of
pings sent and the number of pings lost. In addition, you
can also see the response times (maximum, minimum,
and average).
Detection of Branches / Stub Lines (bridge taps)
– Requires Branch Detection Software Option
(coaxial cable and telecommunications cable only)
The branch detection software option (D720S) is a function extension that enables the detection
of branches / stub lines. Not only can it be used to detect any branches / stub lines that may be
present, but it can also locate them precisely up to a cable length of 150 meters. The branches
/ stub lines, which are di󰀩cult to detect, cause signal reections (echoes) that have a negative
e󰀨ect on the signal and lead to DSL network problems.
You can order the software option with your order or purchase it later from our service depart-
ment (for contact information, see page 26).
Start the test with the scroll bar on Branch by pressing the SEL key. The progress information is
displayed with Branch Detection Running and Progress in
%. If the test was free of errors, a long beep will sound, and the
OK checkmark will be displayed. The LED in the remote ashes
evenly every 1 second.
If an error is detected, two short beeps will sound, and the LED
on the remote unit will ash: 4× briey (0.5 seconds), then a
pause of 1 second, then again 4× briey and so on.
The result is displayed on the main screen. Here the branch
line is readily visible with the exact distance. Lengths below 2
m are not displayed. The measurement is too inaccurate in this
close range.
