2.5 Product feature: Ping
Ping is a tool to help check system
interconnects. Ping is only available
in IP data mode. The test set uses
ping to send a 64-byte packet to the
device being pinged. If the connec-
tion is good, then the device will
return a packet to the test set and
the packet transfer information is
displayed on the test set’s screen.
2.5.1 Protocol logging while pinging
The ability to make a protocol log
while performing a ping to a DUT
(phone) is a valuable feature. This
feature is performed as follows:
1. On the test set, go to the Call
Setup screen.
2. On the Control (left) column of
softkeys, verify that the Data
Conn Type (F4) is set to IP
Data.
3. On the Control column softkeys,
press the More key until you
see “2 of 2”.
4. Press the Ping (F3) key.
Note: The test set can only log data
that travels through the RF link,
such as a DUT ping.
2.5.2 Pinging an alternate device
The E6701A allows an alternate
device, such as your PC on the LAN,
to be pinged. However, you cannot
log an alternate device ping because
the data does NOT travel through
the RF link, but only via the LAN. To
ping an alternate device use the fol-
lowing steps:
1. Press the Ping Setup (F1) key.
2. In the Ping Setup table, set the
device to Ping to Alternate.
3. In the Ping Setup table, scroll to
Alternate Ping Address and
press the knob.
4. Under Value, enter the LAN IP
address of your PC (Refer to
section 2.2.3 PC settings.) Do
not enter leading zeros.
5. Press the knob.
6. Press the Start Ping (F3) key. It
may take a moment for the PC
to respond.
A correct response looks like the
image above. This indicates a func-
tioning IP connection exists between
the test set and the PC.
7. Press Stop Ping (F3) key.
8. On the test set, at the bottom of
the display, note the summary
results data from the ping.
2.5.3 Pinging the DUT
Pinging the DUT, such as a phone or
wireless appliance, can be done as
follows. You can log a DUT ping
because the data travels through the
RF link.
1. In the protocol logging setup,
set the observation point to IP.
2. Start logging.
3. Press the Ping Setup (F1) key
again.
4. Set the device to Ping to DUT.
5. Because it may take a phone
over five seconds to respond,
set the Ping Timeout value to
ten (seconds).
6. Verify that the test set active
cell field indicates “Attached”.
7. Press the phone’s Menu key
briefly.
8. When the display shows “Access
Internet/Select?”, press the OK
key to select.
9. Hold down the Menu key for
about three seconds and
release.
10. On the test set, in the bottom
center of the display, the Active
Cell box should show “PDP
Active” or “Transferring”, this
is required in order to Ping.
(Note: “PDP Active” is the same
as “PDP_Context Active”.)
11. Press Start Ping (F3) key.
12. A correct response looks like
the image below.
This indicates a functioning IP con-
nection exists between the test set
and the phone via the RF link. Note
that the response time of the phone
is variable. (Ignore any GPRS data
connection errors.)
13. Press Stop Ping (F3) key.
14. If you started a protocol log,
stop it, then look at the data on
the PC.
