Might be worth moving up to an honest-to-goodness ADM... there are very reasonable ones for point applications such as these, and they are made for continuous CO operation, unlike the wall-wart powered devices that seem to be so popular. A number of our customers have had some luck with these: http://www.oasystel.com/Products/Minimux155/Minimux155.htm Regards, Andrew Bender taqua.com

Andy,
Thank you for bringing up fiber converters. I have a comment I was trying to bring to the list that escaped this old man's memory.
To the best of my recollection, I have not implemented a fiber converter that lasted more than say, 12 months. I've tried different brands with no luck.
So, my question is, does a 'ruggedized' fiber/coax/X-baseT converter exist?

735 DS-3 cable has a specification max length of 225'. 734 DS-3 cable has a specification max length of 450'. When you use this long cable length, the mux that is providing the DS-3 needs to have the pads removed (or provisioned) for a long cable run.
Transition Networks (and others) make DS-3 fiber converters. They are not cheap. This would be my preferred method as fiber (especially OSP) is much better suited for outdoor exposure and temperature changes.

I need to run a DS3 across our parking lot.. Seriously.
What's the max length I can use coax for (I know, gotta use a GID), and what's the best brand/type of coax I can use? It'll be through innerduct.. Looking for some real world answers from people that do a LOT more of this than me.. (It might take 350-400 feet).
I know this is probably off-topic, but - How does one modify a host record these days? The NSI site is utterly unhelpful on the subject, the web page I bookmarked a few months back no longer works, and the e-mail interface to hostmaster seems to be no longer supported... Any pointers highly appreciated! Grisha

You're right it is off topic, but this particular one has been peeving me for a while so now seems like a good time to bring it up. Host records are actually covered under the web interface. Login to an account and it's the bottom left Quick Link, "Manage Host Servers". The trickier one is creating a contact record for a role account. You can only create individual contacts via the web interface, and submitting the e-mail seems to bounce with "incorrect template version" and a copy of the correct version for the domain registration. I was able to create one role contact by submitting the form about 50 times, but haven't been able to duplicate my success since then. This incompetence brought to you by Network Solutions. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)

This assumes that the host record is named under a domain sponsored by NSI, and that it is COM or NET we are talking about. The most general advice for COM and NET is: 1. determine the parent domain of the host 2. determine which registrar is sponsoring the parent domain (whois.crsnic.net) 3. do whatever registrar-specific thing is required to update the host record. 4. wait until the host record appears in the registry (and in the COM or NET zones, if it results in glue records). 5. cheer enthusiastically. I haven't used NSI for a long time, so I can't comment on your NSI-specific advice. It had a general tone of anger and frustration though, which makes me think it is quite possibly accurate. The absolutely general advice, for all registries, is: 1. determine whether the registry in question even includes the concept of host objects 2a. if it doesn't, stop and scratch your head, but resist the temptation to post to NANOG 2b. if it does, do something registry-specific.
