the rigors of a typical telecommunications working
environment. It can be used in wet conditions but is not
waterproof and will not withstand excessive amounts of
water.

Basic and Primary Rate Interface testers
The BRI aurora
Duet
is designed to test the ISDN Basic
Rate Interface (BRI) at the ‘S’ and ‘U’ reference points, by
emulating either a Terminal Equipment (TE), a Network
Termination point (NT) or a Line Termination (LT).
aurora
Duet
can also test ‘Fixed Links’, or ISDN circuits
which do not need a protocol transaction to establish a
clear channel. For more information, see
