Crocus CNV Configuration attributes
Reference manual 85
6.3 G703 onboard configuration attributes
crocusIfConv<2m/Nx64><Tt/Cv>/g703OnBoard/coding default: HDB3
Use the coding attribute to set the G703 interface encoding mode. Two encoding modes are available:
Value Description
AMI
Alternate Mark Inversion is a bipolar code with no zero substitution.
HDB3
High Density Bipolar 3 is a modified bipolar code.
With HDB3 encoding, more than three consecutive zeroes occurring in the data are
replaced by a substitution word. This to ensure a high pulse density. Therefore,
data links using the HDB3 code can carry data patterns with a low 1 density. Most
of the G703 applications use HDB3 encoding.
crocusIfConv<2m/Nx64><Tt/Cv>/g703OnBoard/tests
Use the tests attribute to enable or disable detection of an RDL test and to set its duration:
Element Description Default value
rdlDetect When set to disabled, this attribute prevents that a digital loop
can be performed by a remote Crocus CNV on the local Crocus
CNV.
When rdlDetect is disabled, and a remote Crocus CNV initiates an
RDL test, the local Crocus CNV will not go in digital loop.
However, the DTE interface of the remote Crocus CNV will be
clamped and data transfer is interrupted.
enabled
testDuration Some tests cause an interruption of the normal data transfer.
Therefore, all tests are automatically terminated after a time-out
period which is specified with the
testDuration
attribute.
The time-out ranges from 00h 00m 01s up to 18h 12m 15s . Entering
00h 00m 00s
disables the time-out period.
