Yes, there are thousands of standards regarding POP construction and POP equipment installation. There are lots of standards bodies who publish standards, although many good ones are still proprietary. You need to be a bit more specific. See ANSI, ATIS, Bellcore(telcordia), ETSI, Factory Mutual, ICBO, MIL-STD, MIL-HDBK and UL to get you started. A major public or university library can help you with your research needs.

small device with IP address
by Mikael Abrahamsson 24 Dec '00

24 Dec '00

Does anyone know if there is a device somewhere that is small, cheap, has 1 10mbit (or 100mbit) ethernet port and a small IP stack that enable you to set ip address and default gateway on it (dhcp perhaps?). I would like to put something like this at some customers to use for pinging to see that the customer is reachable. Cost should preferrably be in the $50-$100 range. -- Mikael Abrahamsson email: swmike(a)swm.pp.se

There are a whole gaggle of them, ranging in price from $200 to $20,000. Each have their own quirks and monitor different things. Everyone does temperature, most do humidity, few do electrical. With dry or wet contacts you can connect additional devices such as door ajar, smoke or leak detectors.

There are also a number of units integrated with some other piece of equipment (e.g. a UPS) or require an additional PC to run the SNMP agent software. What I find interesting is very few people have any type of environmental monitoring, and even fewer monitor the sensors they do have by any operation center. Maybe I'm just weird, and used to monitor too many things too closely. Besides the temperature of their cisco router, do people regularly monitor other environmental parameters in their POPs?

The Cidr Report
by Tony Bates 22 Dec '00

22 Dec '00

This is an auto-generated mail on Fri Dec 22 12:00:00 PST 2000 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

Here is the official BellSouth company line. http://www.bellsouthcorp.com/proactive/documents/render/34382.vtml A lot of marketing hype. However some key points: - Planning for four POPs in south FL which will be fully messed via a DWDM core. - Only one POP will be for co-lo. - First phase will be ATM. Planning on offering Ethernet soon. - Will be carrier independent. Will not be tied to BellSouth, you can use any carrier to connect into a POP. ...djr... > > From: Randy Bush <randy(a)psg.com> > Date: 2000/12/21 Thu AM 08:49:15 EST > To: nanog(a)nanog.org > Subject: florida ix(en) facing south > > > i get rumors of one or more exchange points being built in south florida > where there may be good participation by latin and caribbean networks. > any good gossip, pointers, ...? any choices which are not carrier jails? > > randy > >
