Headend equipment (CMTS's and the router they uplink through) have battery backups AND generators. Why is this? Nodes are generally outdoors and there could potentially be over 100 of them connecting to one CMTS. The tech you spoke with probably doesn't know jack about nodes...probably less than I do. The RF guys (radio frequency) are not geeks like us. They are the guys that work out in the field. They started out as installers and worked their way up (but they never go beyond rack and stack in the headend, that is generally as good as it gets for them).The "cable guys" know nothing about internet service, and we know nothing about RF. Communication between the two factions has never been ideal. I'm not trying to make the cable guys sound like know-nothing grunts...like I said us geeks know nothing about RF...that is THEIR specialty. Now I'm not saying that you don't have a problem at your node! I suggest continuing to call in and complain about outages. They likely may resolve the issue....but you'll never get to know what was actually wrong when they do, your service will just be more reliable without any explanation.

When the building had power maintenance earlier in the year, as soon as street power was cut, all the links went down. Took 5 hours to get a tech out here who basically told us there was nothing he could do, there was no provision for backup power to that closet, so until building power came back on, there was nothing to be done. To say the look on my face was incredulous would be an understatement. I was just praising god that management listened about bringing in another circuit a few months prior, or else we would have been off the grid (and so very very out of SLA) for the duration of that maintenance (our floors had full and proper backup power solutions, but when you're an internet company, and you can't get out to the internet, it's kind of comical)

Thanks for the short story, it filled some more gaps in my knowledge about how the internet works

In the past I would usually still have service when the power goes out which would suggest that a node nearby me has a battery backup that went bad. I called up Time Warner again today asking that they check the battery backups of local nodes that I'm connected to. I was elevated to a level 3 tech that claimed that he doesn't know much about the nodes on the network and cannot check the battery backup status remotely on the nodes that have them. I asked him to send out a tech to check those local nodes that affect me and he just kept saying that they cannot guarantee service during power outages which I already knew. He then put me on hold several times claiming that he had to ask the dispatcher (I doubt he actually asking anybody) and kept saying that he couldn't get an answer. This is the the second time that I've called about the issue and have gotten a similar runaround. Gotta love monopolies. . . If anyone knows a secret to get these people to fix issues please do tell.

Panzer919 wrote: » OK, the headend is the location where all TV transmissions are gathered and changed into channels. The headend would be where you have your biggest routers, multiplexors, multiple trunks to other ISP's things like that. Very similar to a Core Datacenter. This is where the routing happens for all configurations, DHCP, internet traffic, phone calls and video streams. From there all the information gets pumped to the hubsites. They are small buildings that house the local network equipment. It would be closely related to a distribution closet. All connections to other hubsites and the head end are fiber runs. Nodes are the individual runs. So a single hubsite will have multiple nodes attached to it. So if your in Cincinnati, you might be on node TW-CIN-NORTH-101, a couple streets over you have node TW-CIN-NORTH-102 and so on. This is the access layer of their design. This section is all physical, fiber is ran to amps, which not only boost the signal, but change it over to coax frequencies. From there it rides to a street where there are multiple taps. A tap is a small box with multiple coax connections. It is where the tech would connect your house to the rest of the network. The various modems and routers that get connected to a users house are equivalent to an end user. They get IP addresses from a device at the head end, pull configuration files and report data on number of devices up/down. Does that help clarify things?
