Testing in Simulation Mode - Section 1
You can test fixed links with BRI or PRI access, provided the
appropriate interface module is fitted. For Basic Rate you can
test fixed links at the S interface or at the U interface using
2B1Q, 4B3T or Up0 line coding. There are two methods:
• replacing the NT with an aurora
Sonata
• connecting aurora
Sonata
and another device (e.g. a
Agilent Technologies ISDN tester) at either end
of the link, with one emulating a TE and the
other an NT
2 Notes:
• Because there is no D channel protocol, there is no way
to tell when aurora
Sonata
receives a fixed link call. Both
ends of the link must be set up for fixed link operation.
• When aurora
Sonata
is set up to test fixed links you do not
have the option to use ‘any’ B channel (Bx) for the test.
For details on channel selection, see Chapter 3 section 2.
Introducing the ISDN Test Suite
aurora
Sonata
’s ISDN Test Suite offers you a quick and easy way
of performing the most common tests on an ISDN link.
If CorNet-T is selected you cannot use the Test Suite.
