134 Crocus SHDSL G703 Chapter 6 Reference manual Configuration attributes crocusShdslTtRpG703/line/mode This attribute is only present on a Crocus SHDSL G703 2P (2 pair) version. Use the mode attribute to select between single pair or dual pair operation. Default:dualPair Range: singlePair / dualPair When the mode attribute is changed, the Crocus SHDSL G703 reboots. When you change the mode attribute, then make sure that you use the correct speed attribute to set the user speed: If the mode attribute is set to … singlePair, dualPair, then use the attribute … speed to configure the user speed. speed2P to configure the user speed.

Crocus SHDSL G703 Chapter 6 135 Reference manual Configuration attributes crocusShdslTtRpG703/line/minLinePairSpeed Use the minLinePairSpeed attribute to determine what the minimum speed on the line pair has to be when the Crocus SHDSL G703 trains. For more information on the minimum line pair speed, refer to 5.6 - Configuring the minimum line speed on page 87. Default: Range: 192kbps up to 2048kbps (in steps of 64kbps) crocusShdslTtRpG703/line/retrain Use the retrain attribute to determine when the Crocus SHDSL G703 should retrain. Default:- Range: structure, see below The retrain criteria The following criteria determine when to retrain: Criterion no SHDSL frame synchronisation SHDSL frame CRC error threshold exceeded signal to noise too low Description When the Crocus SHDSL G703 cannot synchronise on the SHDSL framing, it retrains. SHDSL framing sends 166 blocks per second over the line, independently of the speed. Each block has a CRC check. When a certain percentage of frames has a CRC error, the Crocus SHDSL G703 retrains. When the signal to noise ratio becomes too low during a certain period of time, the Crocus SHDSL G703 retrains.
