Gratuitous anecdote:
When we moved into 1330 Beacon Street, Brookline, MA (the SS Pierce
Building, 19th c) the phone closet had knob & bolt copper termination
blocks.
At some point the telco, then New England Telephone, came to replace
them with 66 blocks.
As they worked I joked that

I agree that 66 blocks were always simpler for testing and troubleshooting,

Pretty much all of the major LECs have set the goal of full copper
retirement. But that is a long way away.

I'd still go with telect-style blocks. Wire-wrap on the front and amphenol on
the back/bottom depending you application. Way less space than 66 or 110.

Hi Mike. I used Krone blocks back in the mid 90s. I really liked them.
I&#x
When I ran the largest (legacy) dialup ISP in Phoenix in the late 90's
(2000+ POTS lines over a couple sites), we ordered huge frames of 66
blocks... like someone else said better for troubleshooting because you
could pull the bridge clips to test each side and/or troubleshooting
better (or jam
I think you'd be very surprised if you walked into the central offices of
MANY of the large LECs.
The majority of the wire frames are gone, replaced with fiber, even where
the service is delivered as copper to the end user, it's usually served
from something fiber fed much closer to the end user.

Its not ancient. While cooper based products are slowly fading they still
matter. Im using 66 blocks to accommodate gauge/voltage for dial tone in
all facilities. Lots of OOB still happens via copper dial tone or DSL.
Show me one LEC that has torn down their wire frame?

I'm afraid now your long-term options now are probably straight old 66 or 110
blocks. 66 blocks give some added flexibility. 110s are more efficient as far

Currently, we use 100-pr Telect-style termination blocks. They don't offer much
in terms of ease of use for testing and don't organize well on a 19" or 23"
rack.
