ITO – Internetwork Throughput Option
Introduction
The Internetwork Throughput Option (ITO) is a Fluke
OneTouch

Series II Network Assistant software option
that is used to test enterprise-wide throughput or to
evaluate line capacity. ITO’s counterpart, xDSL, verifies
the operation of digital subscriber lines.
ITO and xDSL throughput tests are identical in theory of
operation and will be described in tandem in this chapter.
The two options have different Fluke OneTouch hardware
revision and software version requirements and use
different terminology to reference their technology. Table
7-1 shows common terminology for ITO with its xDSL
equivalent.
ITO/xDSL consists of two components:
Throughput Test – double ended test of network
bandwidth which requires two OneTouch Series II
Network Assistants.
Traffic Generator - tests traffic load capacity.
