via the interface. The following table gives an overview of which tests are available on which interfaces. It
also gives a short description of the available tests.
Interface Available tests Description
interfaceAl The activation of the AL test signal (circuit 141) initiates an
analogue loop (loop 3) on the local Crocus CNV, in compliance
with ITU-T recommendation V.54. Refer to Section
11.5.2 -
Analogue loop .
RS530, V35,
V36
interfaceRdl The activation of the RDL test signal (circuit 140) initiates a digital
loop (loop 2) on the remote Crocus CNV, in compliance with ITU-
T recommendation V.54. Refer to Section
