(Optional) Setting the SNR on a G.SHDSL Interface

(Optional) Setting the SNR on a G.SHDSL Interface

Prerequisites

The G.SHDSL interface has been deactivated.

Context

The device supports the following SNR settings:

  • Uplink and downlink SNRs: When the actual SNR of the device is greater than the configured SNR, the device is activated successfully.

  • Lowest uplink and downlink SNRs: When the actual lowest SNR of the device is smaller than the configured lowest SNR, the device is disconnected.

Procedure

  • Set the uplink and downlink SNRs on a G.SHDSL interface.

    1. Run system-view

      The system view is displayed.

    2. Run either of the following commands to enter the G.SHDSL interface view.

      • If the transmission mode is set to ATM, run:
        interface atm interface-number
      • If the transmission mode is set to PTM, run:
        interface ethernet interface-number
    3. Run shdsl current target snr margin upstream value

      The uplink SNR is set.

      By default, the uplink SNR on a G.SHDSL interface is 6 dB.

    4. Run shdsl current target snr margin downstream value

      The downlink SNR is set.

      By default, the downlink SNR on a G.SHDSL interface is 6 dB.

  • Set the lowest uplink and downlink SNRs on a G.SHDSL interface.

    1. Run system-view

      The system view is displayed.

    2. Run either of the following commands to enter the G.SHDSL interface view.

      • If the transmission mode is set to ATM, run:
        interface atm interface-number
      • If the transmission mode is set to PTM, run:
        interface ethernet interface-number
    3. Run shdsl worst case target snr margin upstream value

      The lowest uplink SNR is set.

      By default, the lowest uplink SNR on a G.SHDSL interface is 0 dB.

    4. Run shdsl worst case target snr margin downstream value

      The lowest downlink SNR is set.

      By default, the lowest downlink SNR on a G.SHDSL interface is 0 dB.
