Hi folks, we seem to be re-iterating some issues that I thought we had
reached consensus on. However in this conversation some good questions
have arisen for the special CCAMP/Q6 meeting. I thought we had consensus that CCAMP will not define new optical impairments, parameters, etc... but we will use ITU-T existing definitions. If we think we need something we will bring this up with Q6. The response we've seen from Q6 so far has been very positive in working together in this area. Some potential questions and areas for discussion: (a) WDM Link characterization -- G.680 gives lots of examples in appendices but does not actually specify yet. There are a host of other ITU-T documents that cover fiber, amplifiers, dispersion compensation modules, etc... So we'll want Q6's input on a somewhat self contained model. (b) Receiver characterization -- Is there are general characterization/parameterization we should use? (c) Transmitter characterization -- Similar question (d) Signal characterization -- There are a number of different documents in this area, some are specific to SDH, some are very general WDM interface characterizations; Guidance would be welcome so that we don't over specialize. (e) Measurements -- G.697 seems to give a rough framework on applications of measurement, types of measurements, measurement parameters. Is this a good place for anyone investigating the relationship between control plane and optical measurements to start? Other recommendations/ideas. (f) Characterization of optical parameters -- (feedback from Q6 desired) parameters that are NE wide, apply to each port, apply between particular ports (port-to-port), frequency dependence of parameters (important for info model and encoding) Other questions for Q6 from CCAMP?
