CMS = Cable Modem Shit
Actually, CMS means Content Management System. This blogger is a type of CMS.First you have to know that there are cable companies and there are Internet Service Providers (ISP) that work with cable companies to bring the internet to my computer. Kind of like telcos and ISPs, if you know what ADSL is. An ISP is a separate entity from cable company. And somehow, perhaps because of this division, ISPs and cable companies don't tend to like each other. Except for where there exists a cable company's favourite ISP. Today a technician came from the ISP I'm subscribed to. He brought with himself 3 modems of the same model as I have, only with different firmware revisions. He was an hour late. He spent an hour fiddling with all the modems. And making phone calls. One was exceptionally tedious, as if he would talk with a man that still visits kindergarten. I bet his child quite often tells him in the morning: "Father, now I'll play here, but you must get to work. Don't forget to pick me up in 8 hours." I got a good impression of the technician though, he seems like a man that knows his stuff, and is quite friendly. Now, on to the problem. The ISP supports only one type of modems with the cable company I'm connected to. Yes, that Israeli shit. He also told me they use other technologies elsewhere, but here it may take some time before they introduce technology that's actually a standard, not some bizarre proprietary crap that's not compatible with anything else. To cut the story short, it seems that the cable company didn't correctly adjust the signal levels for this type of modem. Cable modems use two TV channels for their operation; considering modem's self-diagnostics it appears that the downstream is doing well, but the upstream signal doesn't reach the hub. Bugger. A job for the cable company. And tomorrow the technician will come again. Hopefully then he'll get something done. I STILL DON'T HAVE INTERNET#"$^"$%!@~^#$

Wow, thats some screw-up. So how are you blogging this then, from work maybe?
I've always thought that ADSL and DSL lines are diffrent from cable modems, mainly because ADSL would be a digital subscriber line / phone line.
*shrug* shows how much I know!
PS: Please do enjoy your non-interneting!
Ha! The internet is back! And now I have two modems. That technician couldn't be bothered to pick up one modem he left me to test with it until he comes back. "Eh, just keep it" were his words.
You know, ADSL and cable lines are quite different. I don't know where I wrote they were similar, but they are actually not. The only similarity is in that they both transfer signals. ADSL is a star topology, meaning you don't share your line with anyone else, it connects directly to a router or switch at your ISP (well, the physical line first connects to a PBX at the phone company where they also split the internet signal range from the telephone signal range). In other words, noone can listen to your traffic and you can see no other traffic than yours. You are the sole user of the line. This enables the ISP to always give you the bandwidth you subscribed to. Internet over cable TV is different, no star topology. Just one long line onto which everyone is connected. You can see traffic of other people (at least I can, perhaps other modems filter it out) and you can no longer be guaranteed the bandwidth you subscribed to if they overcrowd the line.

Damnit! You have internet once more? Well, I guess thats ok.
