Vodafone Peering

Does Vodafone peer with anybody in NZ? I've been playing with an HSPDA card, and every traceroute (even to IHUG!) always go directly to the US. I would thought they would at least peer with the other two major Telco's in NZ.

SMS link http://smslink.sourceforge.net/ Pro's works well once setup and tuned. Has support for MySQL Supports all major SMS modems though I'm unsure of the support for Nokia or any cellphone. Con's - slow to process send / receive (as is most software because the msgs get stored on the SIM card first) Good for low traffic, unsuited to bulk send/receive. Note to the person suggesting using a cellphone. SMS modems use a pretty standardised AT command set and you talk to them just like you would to a modem. Cellphones AFAIK usually have proprietory interfaces.

We exclusively use SMS modems here. The Wavecom is the best you can buy and only slightly dearer then the cheaper models. http://www.itx.co.nz/index.php?cPath=29 is a company I've dealt with before and they are allright.

Re: [nznog] Email to SMS gateway

Actually, SMS does offer "guaranteed" delivery. It doesn't matter if the phone is off, an error occurs in communication, a data circuit goes down ... However there are limits. If the message cannot be delivered (such as end device failure) then you can request a receipt to get notification of this. I don't recall ever noticing a lag of hours for SMS delivery (I don't ever recall a TXT taking more than 60s to be delivered) but I guess different TXT processing systems use different methods for getting the TXT into the network for delivery. -----Original Message----- From: Jasper Bryant-Greene [mailto:j(a)digiweb.net.nz] Sent: Tuesday, 17 April 2007 11:15 a.m. To: Philip D'Ath Cc: Samuel Collinson; Dan Clark; NZ Network Operators Group Subject: Re: [nznog] Email to SMS gateway On this - we have found SMS to be a bit unreliable lately, with messages being delivered hours late or not at all. I am aware that SMS does not provide "guaranteed delivery" - what methods are others on this list using to send alerts reliably? Cheers Jasper

Affordable Voltage Monitoring over Ethernet?
by Dan Clark 16 Apr '07

16 Apr '07

Gidday, Just wondering if any network operators etc here are using or have seen any kind of device that can measure voltage/current out there somewhere on a network and we can interrogate it remotely and may even send alerts etc if drops below threshold etc? Would have to be resonably affordable, and in simple kit form or off the shelf. If nothing available that anyone can think of I may develop something along these lines, cheap, simple, ethernet, and probably 12V Open for discussion if anyone remotely interested. Regards Dan

MP3 streaming data usage

Anyone have any idea how much data would be consumed each day streaming MP3 at 128kbps audio stream rate? Thanks.

No. As I said, I come from an Ancient World (TM), where we debugged protocols like DDCMP with a Tek Logic Analayser, scope or logic probe. None of this Ethereal stuff, ethernet hadn't escaped from PARC and Vint was still drawing on envelopes. RS-232 was modern, current loop was till very active (sorry, no pun intended). (Probably Michael Newberry is the only one who will get it anyway, Andy and Sid say they're too young, and the others are looking blank) Each Byte is (or was) a START bit, 8 data bits, PARITY and a STOP or IDLE bit. So we always approximated it to 10 bits. (different devices handle parity bits different ways, it used to be that if there was no parity, no bit was used. LSI USARTS started the trend towards always having a bit used. This is a world where a serial port took up a whole UNIBUS slot (ie a card 400mm by 200mm). As I said, its an approximation for budgeting purposes and comes from an ancient era. Have you found the beer yet ? R

I get 56.25MB... I have this ancient spreadsheet with a few assumptions.... I basically round 10bits to the byte to cover overheads in the packet, etc. So a data rate of say 128kbps is 12.8KB per sec or 0.13Mbps 768KB per minute or 7.68Mbps 46080 KB per hour or 460.9 Mbps or 46.08 MBytes per hour Remembering that you will get silence and various other things (outages, etc) it will always be an approximation. It just gives you a feel for the order of magnitude of the bill :-) Most stations actually have a second stream in reserve for special "promotional" occassions and they kick them into life every now and then, just to muck up the stats. The biggest use of it has been to work out that a 10GB plan is OK for radio stations at 32Kbps streams. Now that 40+GB plans are out, folks are looking at webcams again and it looks like we can stream a camera and stay inside a 40GB plan at 128k video, which isn't too bad looking. I should probably rework the spreadsheet for HD streams at 10Mbps. It looks like 5TB a month. And yes, IPV6 and multicast will solve all our problems, including world hunger and the endless shortage of beer. But I'm showing my age......
