black sheep I am still intrigued by "faulty ports".
As I understand an engineer to do a port swap (lift and shift) has to swap the tie pair, because they have no access to the fTTC cabinet. So these are been diagnosed as faulty ports, but it could be a bad tie pair?
Doesnt it sound odd that these cabinets which are of course expensive would have failing ports at such a high rate?
How do you normally diagnose a bad port, what are the signs? You noticed my posts lately showing a weakened D1 signal? which is the frequency under very low attenuation.
A local engineer diagnosed my issue as bad pairs rather than faulty ports. It seems tho he could have easily diagnosed it as bad ports instead.
If you diagnosing 1 a week bad you will eventually run out of ports in 2 years
