Testing in
Unattended Mode
You can set up aurora Sonata to connect and loop back incoming
data or speech calls on any B channel when left unattended.
This is useful, for example, when investigating a fault which
only occurs occasionally. Instead of watching continuously,
you can leave the tester on site and check periodically to see
whether the error has occurred.
You can leave aurora
Sonata
unattended and set up a link from
another device (e.g. another aurora
Sonata
) to perform BERT or
check audio quality. For an incoming speech call aurora
Sonata
sends DTMF tones down the line before applying the loop.
Notes:
• To allow aurora
Sonata
to run in unattended mode its
automatic power-off feature is disabled, even if you have
enabled it for normal operation. Make sure the tester has
adequate power before leaving it unattended.
• An unattended aurora
Sonata
always connects incoming data
and speech calls automatically, even if it is set up for
manual connection during normal operation.
If
Layer 2
is set to
Automatic
, aurora
Sonata
cannot accept
incoming calls until after the first outgoing call has been
established. If aurora
Sonata
is in unattended mode and
Layer 2
is set to
Automatic
, no calls will be received.
