Mildly OT: NEMA plug guide for dummies
by Olsen, Jason 29 Mar '06

29 Mar '06

So I have a large amount of 802.3af gear going out to sites for new installs and upgrades, which means a lot of new electrical service is being pulled into closets. Despite my best efforts it seems the standard IT-Facilities miscommunications are occuring with the building folks at these sites, the wiring is being done wrong and I'm left to clean up the mess. What's vexed me the most about this is that many of our "remote hands" have no electrical experience at all so they're completely unable to determine the types of plugs and receptacles they're dealing with. I'm left with descriptions that are, I kid you not, as helpful as "the twisty plug with the bent part." If somebody can't tell me if the receptacle is L6-15 or L5-15 I'm going to have a very difficult time sorting this all out and getting the appropriate wiring (re)done. So I'm wondering, has anybody found a good online resource (or a printed resource I can go pick up somewhere) that has illustrations of the different plugs and receptacles found in the wild? It would help me greatly if I could just point somebody to a PDF online somewhere and say "Go to this website, find the receptacle that looks like what has been installed in your switch closet and read the number back to me." I found one at GeneratorJoe.net and while it'll do in a pinch, it's sorta low-quality and I'd like something better.

Problem with IANA blackhole servers
by Sebastian Wiesinger 28 Mar '06

28 Mar '06

Hello, I'm having a problem with the IANA blackhole DNS-Servers resolving RFC1918 IPs. Normally I'm getting a NXDOMAIN reply and this is reported back to the client. With one resolver we're getting SERVFAIL for every query instead of NXDOMAIN. Example: Resolver 1 (working): # dig @192.175.48.42 1.1.168.192.in-addr.arpa PTR ; <<>> DiG 9.2.1 <<>> @192.175.48.42 1.1.168.192.in-addr.arpa PTR ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 50669 ;; flags: qr aa rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;1.1.168.192.in-addr.arpa. IN PTR ;; AUTHORITY SECTION: 168.192.in-addr.arpa. 300 IN SOA prisoner.iana.org. hostmaster.root-servers.org. 2004051800 1800 900 604800 300 ;; Query time: 11 msec ;; SERVER: 192.175.48.42#53(192.175.48.42) ;; WHEN: Tue Mar 28 13:29:57 2006 ;; MSG SIZE rcvd: 119 Resolver 2 (failing): # dig @192.175.48.42 1.1.168.192.in-addr.arpa PTR ; <<>> DiG 9.2.1 <<>> @192.175.48.42 1.1.168.192.in-addr.arpa PTR ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 62187 ;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;1.1.168.192.in-addr.arpa. IN PTR ;; Query time: 16 msec ;; SERVER: 192.175.48.42#53(192.175.48.42) ;; WHEN: Tue Mar 28 13:21:02 2006 ;; MSG SIZE rcvd: 42 So every request to resolve RFC1918 IPs with resolver #2 times out and takes a long time to finish. I think the reason is one of the anycast servers acting abnormal. A trace from resolver 2 points to p80.net as provider: [..] 4 ge0-0-pr1.AMS.router.colt.net (212.74.66.146) 14.100 ms 14.122 ms 14.096 ms 5 cr1.nl.p80.net (195.69.145.52) 14.839 ms 14.731 ms 14.123 ms 6 blackhole-2.iana.org (192.175.48.42) 14.703 ms 15.020 ms 14.861 ms Perhaps someone on this list has a shortcut to get the server back to normal again?

Telecom Convertors for DS1/DS3 signals
by Devon True 28 Mar '06

28 Mar '06

All: I am looking for recommendations for devices that can take a DS3 signal from a carrier via coax, convert it to optical so I can use fiber across buildings to transport the signal, and then on the other side, demux the DS3 signal to individual DS1 channels and terminate them on a RJ-48 port. Any suggestions? I am only looking at one DS3's worth of data to transport across buildings. Distance is around 1000 feet. Thanks! Devon

becoming a LEC
by Philip Lavine 27 Mar '06

27 Mar '06

I have decided to mux down a DS3 into T1's so that my vendors and customers have redundant access to my site. Here is the situation: Right now my customers/vendors ride the ILEC (I am in Burbank)into my building. I have another carrier with an OC3 running into my building so I wanted to take a DS3 off of that and then MUX that down to T1's so I can offer LEC diversity (and possibly upstream diversity). The alternate carrier has agreed to my plan but I am not sure if there is any regulations or standards that I must adhere to. Also how do I get my customers/vendors to choose me as the LEC when they order the redundant circuit? How do I create a LOA/CFA? Thanks, Philip __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

CISCO Hardware question for the masses..
by Micheal Patterson 27 Mar '06

27 Mar '06

Please forgive me if this is inappropriate for the list. We are looking to replace our current security solution with an ASA 5510. Per the info available from Cisco, this should fit the bill but I'm curious if any of you folks have these in place and if there are any gotcha's to it. -- Micheal Patterson .

Speaking of Backhoes, there was a picture I had saved at one point, can't find it now, maybe someone else has it.. It shows a backhoe, half-fallen down into a hole, on fire, huge tower of flames coming up out of the hole. Sitting right next to the hole (this picture was pre-popularity of photoshop, so I assume it to be legit) was a big sign that said "Natural Gas Pipeline, do not dig".
