Re: Copper Termination Blocks

[Mike Hammett <nanog () ics-il net>]

The problem with the Telect-style is that ever time we need to test a given pair, we have to pull it off, it ends up 
breaking, we test, then re-wrap it back on, losing an inch or so each time. For problem loops, this takes a sizable 
amount of wire out of one pair in the 25-pair bundle, then creating other issues.

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'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 as space consumed compared to 66 blocks. Krone and 110s have a very similar 
profile. 
Depending on how much copper you're terminating, you may want to plan the frame layout for cross-connect field space 
before building the frame. You don't want to end up with too much cross-connect wire volume in too small an area. That 
can get troublesome. 
Happy to discuss specifics. Just ping me off-list.

I know I'm discussing what some consider ancient technology. I counter that it meets or exceeds the needs of many, many 
people. 

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. 

I was recommended to look at Krone blocks. They look just great. Easy to break into for testing with their "look both 
ways" plug as well as their preterminated blocks looked much easier to rack-mount. 

Well, Krone was bought by ADC. ADC was bought by Tyco Electronics. TE was bought by Commscope. Commscope discontinued 
everything I found interesting with no replacements. 


Some of the stuff is on eBay (even NIB), some not. 

Any recommendations for places to get old telco blocks, testers, mounts, etc.? 

Any recommendations for alternatives that are easier to source?
