This is a question to query the community on their experience turning up OTS links. I have been presented with the following testing criteria. First, all links will be tested by provisioning channels 1 and 88 and performing a 72-hour test on them. Testing multiple OTS links at once and 1&88 at the same time are allowed. Once completed, we then test the "operational" channels--those that have been planned for on our wavelength plan. The justification for the channel 1/88 test is that there is a RF/analog type frequency response curve (falloff) to the DWDM spectrum. If so, then testing the edges or outside channels successfully will provide confidence that all channels will pass successfully. Thoughts?
