Re: Copper Termination Blocks
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. I can tell you that one MAJOR LEC has a major push going on to retire ALL copper. Shane On Thu, Apr 14, 2022 at 6:54 PM Martin Hannigan wrote: > > > Its not ancient.

As people say, "if it isn't broken, don't fix it". -- That being said, I believe the third stanza is missing; "Optimize it." 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 always found the spades (?) of the 66 block to be convenient to clip a test set (with an angled bed of nails) onto. I've also used slip on jack more than a few times, especially for testing. E.g. Link - 66 block to RJ-45 - https://www.amazon.com/dp/B00F3W7NL4 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. I've never run into Krone myself. I found that using the two sides of a 66 block with bridge clips to be convenient for testing. Especially for building and / or floor entrance points. E.g. incoming network on the left side, outgoing station on the right side, and bridge clips connecting the two. Any time I need to test, pull the bridge clips to split the circuit in a way that's equally as easy to put back. Sure, this technique burns more 66 block / wall space. But I found it to be worth while in some use cases, like building entry. Any recommendations for places to get old telco blocks, testers, mounts, etc.?

Re: Copper Termination Blocks
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? We bought new. Im seeing this product on the intertubes new at $18 per block. We didn’t mount distribution from LEC in rack. Instead we placed the standard 5/8’s plywood backboard and mounted there. We transition to a 110 block in a rack over ladder tray via ABAM cable to deliver to the back of a 110 block and patch from front. Not perfect, but cost effective, easy to manage and simple. It works. Warm regards, -M< On Thu, Apr 14, 2022 at 16:14 Mike Hammett wrote: > I know I'm discussing what some consider ancient technology.

Re: Ready to compromise? was RE: V6 still not supported
Dear Pascal: 1) I had a quick look at the below updated draft. I presume Figure 2 is intended to address my request. Since each IPv4 address has 4 bytes, what are the 12 bytes allocated for IPv4 header fields (outer) and (inner), each? Aren't they the standard first 12 bytes of packet identifier in an IPv4 header? If so, why not show it straightforward as defined by RFC791? 2) If my above assumption is correct, you are essentially prefixing the packet identifying portion (inner) of an IPv4 header with another one (the "outer"), without making use of the existing Options words like my EzIP proposal. How could any existing routers handle a packet with this new header format, without any design related upgrade? If you do expect upgrade, it would appear to me as too much to ask. Am I missing something?

For memory, the main goal here is to find a compromise as opposed to yet another transition solution, though it can be used as a side effect to move along the ladder. The compromise does not change IPv4 or IPv6, tries not to take side for one or the other, and add features to both sides which, if implemented, reduce the chasm that leads to dual stack and CG-NATs. There's value for the movers, lots more public address space for the IPv4-only stack/networks and free prefixes per node and new deployment opportunities for the IPv6-only ones. One major update from the original text accounts for Dave's comment in this list on BCP 38 enforcement, I believe it's solved now. I also added format layouts to Abe Chen's question, and text on the naïve version vs. all the elasticity that exists there and in IP in general to allow real world deployments.

Keep Ukraine Connected
Hi NANOG, for those wanting to help - please see below and https://keepukraineconnected.org for an up-to-date list of needed equipment. Also: "Our contacts in Ukraine are desperately seeking professional grade fiber splicers. If you think you can help, either by donating equipment or financing a splicer, we’d appreciate an email." Forwarded with permission. - Forwarded message from Jan Zorz - Go6 - Dear community, Sorry for another rather long email, but there are more and more requests from Ukraine operators coming in and we have no other way of getting specific equipment other than ask you - the community! Lately we got specific requests for fiber optics welding/splicing kits, specially from Kharkiv region that is/was under brutal attacks and lots of infrastructure is damaged. Let me copy/paste parts of messages that keep coming in so you get the feeling what people that are trying to keep the lights on in the fibers in Ukraine are dealing with: "In Kharkiv we provide continuous network access to other Ukrainian operators and providers. Our network suffers critical loads now because of shelling, and our co-workers repair it, sometimes, under the shots. We lack necessary equipment and tools and are not able to order. There is an urgent need for an optical fiber welding machine (as we have to work in difficult conditions). The amount of work is growing, but the maintenance is missing. We want to ask you, if it's possible, to give us at least one machine fujikura or fitel. We'll be glad to receive even a used one, the most important is it should work." "I also wanted to ask - Do you have, maybe some power backup systems? Also there are our partners in the city - internet provider, who have de-energized nodes for 2-3 thousand active subscribers, in which there is simply no electricity ..." "is there any possibility to send some more of the same optical fiber machines? and if it is possible two or three of the simplest optical reflectometers." We are getting more and more similar requests, so our question to community would be if anyone has any new/used/spare FO welding/splicing kit to donate to Ukraine friends to keep the Internet up&running and people connected? Same goes for UPS systems... We at GNA have secured one Fujikura 41S+ Fusion Splicer Kit with CT50 Cleaver - partially donated by one of their distributors, partially covered by money donations to GNA "Keep Ukraine Connected" initiative that many of you sent in last couple of weeks and we are very grateful for!!! First delivery of requested hardware to Ukraine is now being coordinated with with our colleagues from the Ukrainian Association of Rights Holders and Content Providers, the Ukrainian Internet Association (UAI) and Ukraine Ministry of Digital Transformation and will take place next week. We would like to secure more fiber optics repair equipment and UPS systems before next delivery, so please - if you are willing and can help - contact us at ukra...@nogalliance.org for hardware donation or donate some funds at below web page so we are able to purchase needed equipment and send it to Ukraine with next delivery. https://keepukraineconnected.org/ Thank you again, Jan Zorz on behalf of GNA/KUC initiative
Re: Copper Termination Blocks
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. -Original Message- From: "Dave Phelps" Sent: Thursday, April 14, 2022 4:27pm To: "Mike Hammett" Cc: "NANOG" Subject: Re: Copper Termination Blocks 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.

Re: fs.com Ethernet switches
Using a cheap POE switch. I'm pretty happy with it since it's cheap. It's a bit noisy with a small load would be my only complaint - I suspect it's the same volume at full load. No management/layer 3 features on mine nor do I want them. I don't know if L2 only means you want management or not.

Same experience here. So far so good and their TAC is efficient. I had to disable MCLAG settings due to a strange behavior with multicast.
