Introducing
aurora
Sonata
aurora
Sonata
allows you to test ISDN links on a range of
different interfaces depending on which interface modules are
fitted.
aurora
Sonata
may be fitted with S and/or U interface modules for
testing Basic Rate links and a Primary Rate (PRI) module (E1
transmission).
How you can use your aurora
Sonata
Depending on the type of test you perform, you can check one
or more of the following:
• ISDN equipment and lines
• the route through the network via ISDN switches
• the operation of the call control protocols
• ISDN fixed links, which do not use protocol support
• the integrity of a call and the quality of service
• the availability and operation of ISDN services
The basic methods for testing
There are two main ways in which you can use aurora
Sonata
—
these are known as the operating modes. They are:
• Simulation mode—you use the unit to simulate the
operation of Terminal Equipment (TE), a Network
Termination (NT) or a Line Termination (LT).
aurora
Sonata
can generate or receive the network clock
and act as the protocol ‘master’ (network side), or
‘slave’ (user side).
• Monitor mode—aurora
Sonata
monitors user traffic and
protocol information on the line in real time.
