Cisco Adsl ATU-R Dmt Configuration Interleave Fec Size

1.3.6.1.4.1.9.9.130.1.14.1.11

This object specifies the initial number of FEC redundancy bytes the ATU-R appends to upstream frames transmitted over the interleaved channel during the training sequence. The ATU-C can force the ATU-R to fallback from this value depending on the aggregate data rate achieved during training. It is desirable to choose a large FEC size, thereby increasing the chance of being able to correct errors in the data delivered by a frame. However, additional FEC redundancy bytes increases frame overhead, and thus frame latency. The value of this object must be a integral multiple of the value of cAdslAturDmtConfCodewordSize.
