ITO/xDSL Theory of Operation
The ITO Throughput test refers to these two units as the
local and remote units and the xDSL Throughput test
refers to these two units as the subscriber-end unit (ATU-
R) and the central office unit (ATU-C), respectively. Both
options are double-ended tests of bandwidth which
require two Fluke OneTouch Series II units to execute the
test. Figure 7-1 shows the relationship between the local
unit (ATU-R unit, for xDSL) and the remote unit (ATU-C
unit, for xDSL).
For the ITO Throughput test both units must have
software version 4.50, or later. Only the local unit must
have the ITO option enabled.
For the xDSL Throughput test, the central office unit
(ATU-C) must have software version 4.50 or later but the
xDSL option is not required. The subscriber-end unit
(ATU-R unit) must have software version 4.50, or later
and must have the xDSL option enabled.

Started Manual
(P/N 1595893) and the OneTouch Link
program online help for more information on enabling
options.
Note
For the best operation, it is recommended that
you update all of your Network Assistants’ xDSL
software version 4.50, or later.
For the ITO Throughput test, a second, unattended
Network Assistant (the remote unit) is used as a remote
traffic source. For the xDSL Throughput test, a second,
unattended Network Assistant (the ATU-C unit) is used as
a remote traffic source. The subscriber-end unit (ATU-R
for xDSL) is used to configure the test, execute the test,
and display the test results.
