The off-topic thread

How to get your customers to use the right dial-up number is presumably on topic for NANOG. I know that when I worked for a dial-up ISP many years ago, it was frequently a big issue for our customers. However, the more general topic of how to dial a phone call in various parts of North America is presumably something that NANOG readers who need to make phone calls in North America can figure out on their own, or for which they will at least be using references other than the NANOG archives. While comprehensive documentation of how to make phone calls from various locations all over the world might actually be quite useful, the NANOG list really isn't the place for it. How dial plans should work really seems like a question for phone network operations list, although people on such a list would probably consider the question long since settled. NANOG is an Internet operations list, where we tend to deal with IP addresses and domain names rather than phone numbers. -Steve One of the list administrators

All well and good. *UNTIL* you get assigned an NXX NPA that is _already_ in use as a prefix. 773, 847, and 630 were _all_ in use as prefixes within the 312 area-code (and in the split-off 708 areacode as well) before those sequences were "legal" as an area-code. "Now What?" applies. <wry grin> > > That isn't even necessary, though; if 214-817 existed, there's no way of > confusing it with 817-xxx because all calls are either 10D or 11D. Maybe in *your* territory. :) In 312/708/630/847/773/224, dialing patterns are 7D or 11D ( 847/224 is 11D only) > Such a > tactic is only needed during the transition from 7D to 10D local dialing, > which happened here a decade ago. Lots of places have *NOT* made that transition. It is fairly _expensive_ for the telcos to implement. > For the same reason, we no longer have an excuse for not using 0XX, 1XX, and > X11 as prefixes. "Speak for yourself, John" applies. _Mandatory_ 10D dialing does *not* exist (yet) in *many* areas Mandatory 10D dialing does have non-trivial costs associated with it -- both to the telco, and to the customers thereof. There _is_ a significant performance issue -- and directly related increased costs -- in supporting mixed 7D and 10D dialing. To use 1+ for "toll alerting", in locales where intra-NPA can be toll, and inter-NPA can be local, you have to incur one of those sets of increased expenses. And the 'inconveniences' to the customer. It is a trade-off as to which is 'worse' for the customer. <wry grin> Different utility commissions have decided that issue in different ways. > We're already using [2-7]00 prefixes, but I'm not > surprised we don't yet (AFAICT) have 800 and 900 prefixes.

You need a more cosmopolitian view -- This scheme has been in effect for 20 years, locally. *NO* chance of getting it reversed. In other major metro areas something very similar has been in effect for much longer. Most big-city systems have charged on such a basis for a long time now.,

Operational: Outage inside Teleglobe ?
by Ashe Canvar 19 Aug '05

19 Aug '05

Is anyone aware of an outage this morning (9:30Am PST) inside Teleglobe's backbone and the reasons thereof ? Thanks, -Ashe P.S. I no longer see operational posts on NANOG. Is there some other list that is more relevant for this kind of discussion ?

Hi, I know RIP is outdated and IETF doesnt support it anymore. Knowing this i couldnt think of a more appropriate place to post this query: I keep seeing RIP packets with a tag field filled with some non zero number. Any clues on why this is happening? I know that the border routers were meant to use this to fill their AS numbers there, but is there any vendor that really uses this. Moreover, does it make any sense now in doing so. Thanks, Tom
