Andrea shows the slides provided by Roshan. After some discussion, agreed the following way forward:
- Deprecate DSR and OTN layer protocol names from SIP and NEP at UNI and ENNI.
- This because DSR and OTN actually represent the supportable service layers, rather than the layer of the (bottom most) SIP/NEP.
- Recommend in the RIA to use either PHOTONIC_MEDIA or ELECTRICAL_MEDIA (identity to be added) for SIP/NEP at UNI/ENNI.
Nigel clarifies that the NEP referring an Access Port is the logical entity which is nearest to a physical entity.
- For TM Forum MTNM, this is the PTP (Physical Termination Point) entity. TAPI has evolved by inserting a "PTP" at each layer network, which allows same repeatable pattern at any network slice.
