I should clarify. The "ADM trib" I'm referring to here is when the
transmission gear (ADM) is located in the same facility as the routers and
local loops are a non-issue.
As for two local loops w/APS, one protecting the other, there are certainly
precautions that can be taken to avoid a great deal of the problems that folks
have shared here over the years, some obvious some not. But simply handing
over another $100K for a second port, simply to protect against router
failures, isn't always a sensible .. or viable option.
