Whether technicians
are testing frame relay, ATM or packet over Sonet, a
capable protocol analyzer will help get the job done
right
When testing any type of WAN system,
carrier technicians run into two major problems: "I
can't connect to...." That's the connectivity problem.
And "the @#$! network is so slow!" That's the
performance problem.
Whether carriers are dealing with frame
relay, asynchronous transfer mode or more advanced packet-over-Sonet
technology, they can easily fix these problems given the
right tools and know-how. They can use two methods for
testing and troubleshooting:
- The passive method, in which a technician
only analyzes the traffic on a line.
- The proactive method, in which a technician
replaces one end with a known objective device that can
emulate the specific network facilities under test.
The complexity of WAN systems such as
ATM and packet over Sonet makes testing a crucial part
of these networks' life cycles. The modern network professional
needs a good protocol analyzer in the toolbox--one that
can monitor in real time, generate traffic and emulate
network entities. A physical layer tester is just not enough.
