It has been awhile but if I have a male/male and a female/female amphenol and need to chain together to connect a 66 block with amphenol to a system with amphenol does that chaining flip the pin-out? or is it still 1 at top of block and 25 at the bottom?

I did this a couple of weeks ago but with a m/m amphenol cable and a m/f amphenol cable. The pinout remains the same. That is 1 is at the top.

All you would have to do is think of the problems "flipping" the pinouts would cause and you would realize that doesn't happen.

With 25 pair connectors (Amphenol, Amp, Cinch, etc.), pins 26 and 1 are always white/blue and blue/white, respectively. For cables that connect to stations or trunks, this doesn't normally come up for discussion. The difference is when cables using these, or similar, connectors might have a brand-specific pin configuration. This is often the case with cables that connect between cabinets.

The question of 'flipping' or reversed polarity really applies more to modular cords. Standard line cords for telephone sets are usually flipped. The polarity correction, if necessary, it made by the jack inside of the telephone set itself. Of course, the flipping of pairs in modular cords used for T1/PRI or Ethernet are a more common issue. In those instances, there is no in-between. It has to be maintained straight-through polarity in most instances. The exceptions are fairly rare though.
