    The TAOS software creates an al-dmt profile for each ADSL-DMT interface in a Stinger unit. The profiles are identified by the chassis and slot location of the LIM that provides them. One profile is created for each interface supported by the LIM in a specific slot.

    Noise margin parameters The margin-config subprofile contains the parameters that configure noise margins. Noise margins are defined in decibels (dB). A BER of 10 represents 0dB. The line Stinger® ADSL Annex A LIM Guide for LIMs with ADSL2+ Capability 2-11...

  • Page 32: Figure 2-1 Noise Margin Parameters And Power Adjustments Relationship

    Increase output power 0dB margin On many loops, the Stinger unit uses large power margins. To avoid excessive power margins, you can configure the Stinger unit with a maximum downstream noise margin value that it translates into a maximum power output value. The Stinger unit attempts to reduce the transmit power by a maximum of 12dB to achieve the desired maximum downstream noise margin.
  • Page 33 Lucent Technologies license for ADSL2+ is installed on the Stinger unit. When dynamic rate adaptation is in use, the downstream line adjusts its bit rate dynamically (it upshifts to increase its bit rate or downshifts to reduce it) on the basis of specified noise margins and intervals for which a noise level is maintained, provided that the maximum or minimum bit rate has not been reached.

  • Page 34: Figure 2-2 Future Noise Margins And Dynamic Rate Adaptation Relationship

    The following parameters configure dynamic rate adaptation for ADSL Annex-A LIMs with ADSL2+ capability. They are only valid when the Lucent Technologies license for ADSL2+ capability is installed on the Stinger unit, and the rate-adapt-mode parameter is set to dynamic. The following example illustrates their default settings.

    SPVC remains connected. Connections are broken only if the physical slot or line stops operating or is disabled by an administrator. By default, the Stinger unit monitors the physical line state of its interfaces and allows connections to be established only when the line state is fully connected.
