On the TT, you can configure the interconnection between signal ground and protective ground (earth).
Use strap ST1 for this purpose. For the location of ST1 on the TT motherboard, refer to Section 3.1.1
Location of the DIP switches and straps on the Table Top.
Strap settings Connection Description
disconnected
As default, the signal ground is disconnected from the
earth. This avoids problems which might occur when the
earth potential of the Crocus CNV and the connected
application is not the same. In such a situation earth current
loops may induce distortion on the transmitted data,
resulting in transmission errors.
connected through
100 ohms resistor
Sometimes you might want to connect the Crocus CNV
earth to the application earth although both earth potentials
are not the same. (E.g. to avoid a big difference between
both earth potentials.) To avoid that high earth currents are
generated, you can make this connection through a 100
ohms resistor.
directly connected Sometimes it is not possible to connect the application
directly to the earth. In that case you can earth the
application through the Crocus CNV by connecting the
Crocus CNV to the earth and setting strap ST1 in position
3.
Also the opposite situation might occur: it is not possible to
earth the Crocus CNV. In that case you can earth the
Crocus CNV through the application by connecting the
application to the earth and setting strap ST1 in position 3.

5.2 Loading the default configuration
If you install the Crocus CNV for the first time, all configuration attributes are set to their default value. If
the Crocus CNV has already been configured a number of times and you want to reconfigure it starting
from scratch, it might be best to load the default configuration.
Also, when you accidentally made a configuration error which, for some reason, makes the Crocus CNV
inaccessible for TMA, you can load the default configuration using the appropriate DIP switch. For
instance: you defined a password in the Crocus CNV but you can not remember it. In that case you can
not access the Crocus CNV with TMA if you do not supply the correct password.
You can load the default configuration

5.3.2 The different clocking modes
This section explains the different clocking modes. The following table gives an overview:
Clocking mode Description
internal The Crocus CNV generates the transmit clock signal and sends it to the
application via the TxClk circuit (circuit 114).
Internal clocking can be selected in combination with preferred or alternative
clocking. See below.
slave receive The transmit clock signal is derived from the received line data. This
reconstructed clock signal is sent to the application via the TxClk circuit (circuit
114).
Slave receive clocking can be selected in combination with preferred or
alternative clocking. See below.
external The application generates the transmit clock signal and sends it to the Crocus
CNV via the ExtTxClk circuit (circuit 113).
Internal and slave receive clocking can be selected in combination with preferred or alternative clocking:
Clocking mode Description
preferred The application loops back the output of the TxClk circuit (circuit 114) to the
ExtTxClk circuit (circuit 113). This guarantees an optimal phase relationship
between the transmitted data and the transmitted clock. This because the
transmission delays of the TxD circuit (circuit 103) and the ExtTxClk circuit are
exactly the same, since the outputs of both circuits originate in the application
and are fed into the Crocus CNV.
alternative This does not require the TxClk (circuit 114) to ExtTxClk (circuit 113) loop-back.
In this case the clock is looped back within the Crocus CNV itself.
It may be necessary to use preferred clocking when delays are introduced in the communication between
the DTE and the Crocus CNV. Delays may occur in case of long interconnection cables.

5.3.3 The presence of the external clock signal
The presence or absence of an external clock signal may influence the clocking mode that is actually
chosen by the Crocus CNV. This section explains how.

5.3.5 Special points of interest concerning clocking on the X21 interface
The following are some special points of interest concerning clocking on the X21 interface:
• In internal clocking modes, the S clock is the transmit clock. There is always a retiming buffer in the
receive direction (slave transmit), independent of the rxClk attribute value. The receive data is clocked
out with the internal clock.
• In slave receive clocking modes, the transmit and receive clocks are the same. Hence, there is no
difference with other interfaces.
• In external clocking mode, the S clock is the receive clock.
• It is possible to invert the transmit sample clock on the X21 interfaces. In case of alternative clocking
modes, inversion solves the possible problem of too long delays on the transmit data (from DTE to
DCE) in comparison to the transmit clock (from DCE to DTE). The inversion can be done by means of
DIP switches (refer to Section 3.2.3 - DIP switches of the Card Version).

5.4 Configuring the onboard G703 interface
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/longHaul default: enabled
The onboard G703 interface is equipped with a driver. This enables you to cover long distances. The
driver can be enabled or disabled.
The distances that can be covered are in the order of:
• 2.5 km using a cable with a diameter of 0.6 mm
• 1.25 km using a cable with a diameter of 0.4 mm.
Important remark
On a Crocus 2M CNV CV and on a Crocus Nx64 CNV CV in unframed mode, it is not possible to start an
RDL test or receive a DL test from the remote side when the device is strapped in short haul (i.e. longHaul
= disabled). However, it is possible to start a DL test directly on the device itself.

Unframed and framed mode
The following table explains the difference between unframed and framed mode.
Mode Description
unframed
(transparent)
In unframed mode, a 2 Mbps data stream is sent transparently over the line.
framed
(G.704 framing)
In framed mode, up to 31 time slots each containing a 64 kbps data stream can be
sent over the line. Each 64 kbps time slot can be enabled or disabled. Time slot 0 is
reserved for synchronisation and signalling.
Selecting unframed mode
Select unframed mode by setting time slot TS0 to 1 (enabled). The value of the time slots TS1 up to TS31
is irrelevant.
Selecting framed mode and allocating time slots
Select framed mode and allocate time slots as follows:
1. Set time slot TS0 to 0 (disabled) to enable G.704 framing.
2. Allocate the desired time slots by setting them to value 1 (enabled).

5.6.1 Rules of thumb and remarks concerning management
The following lists some rules of thumb concerning the management of OneAccess devices in a network:
• Make sure there is only one path towards the management system. Else you might get unexpected
results (e.g. devices that do not answer to polling, answer of several devices at once when polling one
device, etc.).
• Once your network starts to become complex on management level (i.e. more than just in-line
connections as depicted in Section 6.5 Management configuration attributes), you are advised to use
absolute addressing instead of relative addressing.
In practice, it is best to use absolute addressing when you configure one of the attributes listed below
as follows:
− ctrlPortProtocol attribute to management.
• If you use a router interface in the Crocus CNV, then you are advised to set the ctrlPortProtocol attribute
to management. Else you might be unable to manage the router interface.
• The Crocus CNV is not a true multi-device (a multi-device is a device that incorporates several
devices on one card, such as the Crocus SHDSL CV Twin). However, if a router interface is inserted
in both modular interface slot A and B and the ctrlPortProtocol attribute is set to …
− console, then the router interface in interface slot B is linked to “modem B”. In practice, this means
that when using e.g. a management concentrator you have to specify modem B in your exit port
settings.
− management, then the router interface in interface slot B is linked to “modem A”. In practice, this
means that when using e.g. a management concentrator you have to specify modem A instead of
modem B in your exit port settings.
• Changing the ctrlPortProtocol attribute causes the Crocus CNV to reboot.

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.

The following table explains the difference between unframed and framed mode.
Mode Description
unframed
(transparent)
In unframed mode, a 2 Mbps data stream is sent transparently over the line.
framed
(G.704 framing)
In framed mode, up to 31 time slots each containing a 64 kbps data stream can be
sent over the line. Each 64 kbps time slot can be enabled or disabled. Time slot 0 is
reserved for synchronisation and signalling.
Selecting unframed mode
Select unframed mode by setting time slot TS0 to 1 (enabled). The value of the time slots TS1 up to TS31
is irrelevant.
Selecting framed mode and allocating time slots
Select framed mode and allocate time slots as follows:
1. Set time slot TS0 to 0 (disabled) to enable G.704 framing.
2. Allocate the desired time slots by setting them to value 1 (enabled).
