"Real Soon Now", they promise. a few others have asked me over the past little bit, i'll pass this on, thx. > In reality though, setup costs pale into relative insignificance when you > consider the long term (~$250/month) running costs for an Onramp2 with a > 64k data call cap. a side issue but sort of relevent, would anyone running isdn know what sort bit rate (maximun traffic) can be expected from a 64 kbit, 128 kbit or even a 256 kbit link before saturation sets in links fallover so to speak. in the old days i worked out that if i could get a 33k6 circuit to the back bone this would be as good as running a 64 kbit isdn (our isdn feeders are not to reliable in my part of the world, more so with the selloff). hence the interest in frame relay or even multiple 33k6 (or v.90) with some sort of pstn based 'channel bonding'. off cource the effective 128 kbit path to the back bone (3x33k6 pstn pots circuits) at dirt cheap rates has nothing to do with this line of questioning ... grin. > > ps, hello, rowan. > > G'day. :) > > Cheers. hope things are ok in your camp. regards jonathan -- =============================================================================== Jonathan Michaels PO Box 144, Rosebery, NSW 1445 Australia ===========================================================<jon@caamora.com.au> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
