User manual 


3.1 Connecting the NE side and FE side 

When you set up an SHDSL link, the central SHDSL device has to be master and the remote SHDSL 

device has to be the slave (e.g. refer to the configuration attribute ”channel“ on the Crocus SHDSL 

modem). 

The SHDSL interface of the Crocus SHDSL Repeater 2P consists of two “sides”: 

SHDSL interface 

side 

NE side 

FE side 

Description 

This side operates in slave mode and has to be connected to the central 

SHDSL device. 

If there is more than one repeater in the link, then the NE side of one repeater 

has to be connected to the FE side of the other repeater. 

This side operates in master mode and has to be connected to the remote 

SHDSL device. 

If there is more than one repeater in the link, then the FE side of one repeater 

has to be connected to the NE side of the other repeater. 

In case of the …

that is configured on the FE side of the connected SHDSL device. If the line rate 

of this neighbouring SHDSL device its FE side is set to … 

- a fixed line rate, then the NE side of the Crocus SHDSL Repeater 2P adapts 

its line rate to this fixed line rate. 

- rate adaptation mode, then the NE side of the Crocus SHDSL Repeater 2P 

and the FE side of the SHDSL device try to achieve the highest possible line 

rate which gives a stable connection.

User manual 


3.3 Performance monitoring 

The transmission performance of the SHDSL link can be monitored in two different ways: 

• the SHDSL signal quality. This is typically used during installation and maintenance procedures. 

• the G.826 error performance parameters. These are intended to be used for long term evaluation of 

the SHDSL link. 

Also refer to the “SQ” and “G826” monitor commands described in 4.5 - Performance management (PM) 

on page 42. 

G.826 Performance Monitoring 

The G.826 error performance parameters provide quantitative performance information of a specific 

loop. They are intended to be used for long term evaluation of SHDSL links. 

The evaluation of the G.826 error performance parameters is based on CRC (Cyclic Redundancy 

Check) error detection: 

CRC generation and detection on the repeater are handled separately for the FE side and NE side. On 

each side, six CRC6 check bits are generated per SHDSL frame for each channel and direction. For signalling 

detected block-errors in the return direction, the FEBE-bits are used. The SHDSL G.826 performance 

of the opposite unit is calculated according to these FEBE-bits. CRC6 errors are used by software 

to count the block-errors of the respective SHDSL channel and to evaluate its error performance according 

to ITU-T Rec. G.826. 

The estimation of a bit-error rate is not within the scope of the G.826 calculations.

3.4 Monitoring the Crocus SHDSL Repeater 2P with TMA 

Using the monitor interface, you can configure the Crocus SHDSL Repeater 2P and monitor the status 

and performance. Refer to 4 - Monitor interface on page 37 for more information. However, it is also possible 

to monitor the status and performance of the Crocus SHDSL Repeater 2P and to activate loop-back 

tests on the Crocus SHDSL Repeater 2P by using TMA. This is not possible by connecting TMA directly 

to the Crocus SHDSL Repeater 2P, but by connecting to a Telindus SHDSL device and retrieving the 

information from the Crocus SHDSL Repeater 2P over the EOC channel. 

The following gives an overview of this section: 

• 3.4.1 - Starting a TMA session on page 34 

• 3.4.2 - Activating a test loop with TMA on page 35


User manual 


3.4.1 Starting a TMA session 

As said before, you cannot connect TMA directly to the Crocus SHDSL Repeater 2P. You have to connect 

TMA to a Telindus SHDSL device which, on its turn, is connected to the Crocus SHDSL Repeater 

2P. This section explains this. 

Suppose you have the following set-up: 

Now, in order to retrieve status and performance information from the Crocus SHDSL Repeater 2P 

through the Crocus SHDSL and to display it in TMA, proceed as follows: 

Step 

Action 

1 Connect TMA to the Crocus SHDSL. Refer to the manual of the Crocus SHDSL how to 

do so. 

2 Make sure that on the Crocus SHDSL the attribute line/eocHandling is set to anything else 

than the value “none” (e.g. discovery, inventory, info or alarmConfiguration). 

3 In the containment tree of the Crocus SHDSL, go to the 

object repeater[ ]. In this object you can find some status and 

performance information of the Crocus SHDSL Repeater 2P. 

Refer to the manual of the Crocus SHDSL to find out more about these attributes.
