ISP Information:
This was a very common copper wire standard between 1996-2002 and today. It uses an RJ-45 plug and four-pair wire like Cat 3 and Cat 4, but it is certified to run up to 100MHz and is suitable for 100Mbps wiring standards. Higher speeds are possible, and some installers certify Cat 5 wire at 155Mbps or more.

The Centrex ESS still accepts rotary dial pulses and the ringing current still rings the telephone. Voice clarity is fine. Definitely -- they were built for a minimum service life of thirty years. That they've lasted nearly twice that is a good indicator of the quality WE was able to achieve. It would be interesting to find out how much in today's dollars the manufacture of a 302 would cost. I bet it would be a few hundred dollars or more.I wouldn't even begin to try to estimate that, nor would it make anysense in today's marketplace.Back in the days when *The Phone Company* owned everything (includingthat phone on your nightstand), it actually made perfect economicsense to design and build everything for that kind of a service life.The time and labor cost ofa) dispatching a repair technician every two years or so /per phone/b) having to maintain a larger labor force of technicians, even if allthey did was replace phones in place rather than actually repair them,andc) manufacturing more phones as the old ones could no longer berepaired (remember the not insignificant costs of running morefactories)would quickly overshadow the cost of manufacturing a phone whichneeded (almost) no maintenance.So, in this particualr case, it seems that the old book "Quality isFree" from the early 80's had more than a grain of truth in it.But that was then and now is now. We now "repair" our own phones bythrowing them into the trash heap and replacing them with new ones wepurchase at the local Wal-Mart or Staples.
