60minsOTSi Model

Nigel Davis

  • Media Channel in TAPI is modeled as an OTSiG Connection (bundle of OTSi media channels)

  • Media Channels in ITU-T - Constraining, concatenating and filtering the signal spectrum (ignores that OTSi requires DSP to resolve the spectrum)

  • Disaggregated Node with Overheads and no amplifiers

  • Schematic with amplifier put back in the picture


  • Relationship of OMS-OTS to OTSi
45minsGithub Issues

Andrea Mazzini

  • ETH VLAN Config - Issue #133
    • ETHG (group of VLAN IDs) is used for OAM purposes where only a single VLAN is monitored

    • All VLANs in ETHG has to be co-routed, but beyond the scope of the OAM ME/MA, each of these VLANs may have separate route. Thus ETHG is not necessarily E2E.
    • But from an UNI-N side, all these VLANs are/should be bundled. So effectively they are a single connection

    • Is the below valid to model or monitor as a bundled-connection even if they belong to different services and if they are co-routed in the transit domain. No if needs to be done, OVC (S-Tags) has to be used.
