WT-355 YANG Modules for FTTdp Management:

2017.446 - Changes for inclusion in WT-355c2. The following items were discussed:

• Line 380 in bbf-fast-pointers.yang, agreed to update description

• Line 434 in bbf-vdsl-impulse-noise-protection-delay-profile-body.yang, agreed to deprecate upstream mdosplit and explain in the description that upstream + downstream = 100% so that's why upstream was deprecated.

• Line 476 in bbf-vdsl-impulse-noise-protection-delay-profile-body.yang, agreed to deprecate upstream and fix description

• Line 504 in bbf-vdsl-impulse-noise-protection-delay-profile-body.yang, agreed to deprecate upstream and fix description

• Line 119 in bbf-vdsl-line-spectrum-profile-body.yang, no change agreed

• Line 137 in bbf-vdsl-line-spectrum-profile-body.yang, agreed to add default "all" to power-management-mode

• Line 202 in bbf-vdsl-line-spectrum-profile-body.yang, agreed to add must statement: l2-maximum-aggregate-power-reduction-per <= l2-maximum-aggregate-power-reduction-total

• Line 253 in bbf-vdsl-mode-specific-psd-profile-body.yang, not agreed, no change made to upstream_psd_mask_selection

  • Agreed to add text to OD-360 noting that backward compatibility is more important than changing style issues.

• Line 152 in bbf-vdsl-noise-margin-profile-body.yang, agreed to expand the must statement for maximum-noise-margin by adding: or (max == "unbounded")

• Line 370 in bbf-vdsl-pointers.yang, leaf line-config-vector, no change agreed

• Line 380 in bbf-vdsl-pointers.yang, threshold-template, agreed to add to description field: "If no template is configured, then TCA reporting is disabled."

• Line 103 in bbf-vdsl-virtual-noise-profile-body.yang, grouping vn-descriptor, agreed to make max-elements be 16 for upstream and 32 for downstream

• Line 167 in bbf-vdsl-virtual-noise-profile-body.yang, virtual-noise-profile (downstream), agreed to add a must statement so that there cannot be a single element

• Line 219 in bbf-vdsl-virtual-noise-profile-body.yang, virtual-noise-profile (upstream), agreed to add a must statement so that there cannot be a single element

• Line 270 in bbf-vdsl-xtu-band-status-body.yang, upbo-electrical-length-pbn, agreed to add to description "For ADSL systems, a single parameter is defined for band = 0, as a single band is usable."

• Line 302 in bbf-vdsl-xtu-line-status-body.yang, profile, agreed to remove config false; (other spurious config false; occurrences should also be searched and destroyed)

• Line 420 in bbf-vdsl-xtu-line-status-body.yang, attndr-actual-method, agreed to change valid range to 0..2

It was agreed to create a WT-355 Corrigendum 2, post it on Bitbucket, and proceed to a rapid straw ballot

2017.485.01 - Awareness of new FTU Management Counter

• Notes that a new counter is being defined by the ITU for G.fast: All Normal Operation Interval (NOI) Error Free Throughput (ANDEFTR). This is likely to be consented by the ITU in June, there is no action by the BBF at this time but we should be ready for it.
