When your number moved from 414 into 262 everyone in the new 262 area had to tell all their friends outside the 262 area that their numbers had changed. There may be a few people who still never call anyone outside their home town, but for everyone else, it's a significant pain. With overlays, nobody's number changes. > Geographically, area codes fail to have meaning if they are overlaid ... Uh, since the boundaries haven't changed, they mean exactly what they meant all along. The meaning of 212 didn't change when they overlaid 626 on it. It's still Manhattan.

The duration that the UPS can maintain that 600 VA (or the total stored power) is a separate item in the datasheet. If the time the UPS can handle is rated at full load then running at 100 VA instead of 600 means the UPS can keep the system running for roughly 6x as long. - - Stephen ***** Moderator's Note ***** The specifications for this model of UPS are at - http://www.apc.com/shop/us/en/products/APC-Back-UPS-BE600M1-600VA-120V-1-USB-charging-port/P-BE600M1 Depending on load, it has runtimes between 6.1 minutes and 1 hour 5 minutes.

I don't know about most of the country, but in my area Verizon has made it quite clear publicly it is not interested in maintaining its existing landline network. It actually has abandoned some neighborhoods, telling them to get FIOS or go away. A neighbor, an elderly man in poor health, lost phone service. It took Verizon ten days to fix it, causing him no end of grief while he waited (including Vz not showing up as promised). In the end, they just switched him to a different cable pair, which is a quick and easy fix. My landline had trouble and I had similar frustrations with Vz. My community does not have FIOS. FIOS is no panacea since that requires house current and its backup batteries will fail during an extended power failure. At least my landline kept working during a long power failure (I am close to the C.O., which has generator backup). Cable phone (provided by Comcast) goes out the minute the power fails, and takes a while to come back. It is not that reliable. Dealing with Comcast is frustrating. Their people all follow pre-written scripts and can't fix anything not covered in the script. A friend lost his Comcast landline and had to wait until a senior technician could come out (the plain tech couldn't fix it). A big part of the problem today is that everyday consumers no longer care about the high reliability the old Bell System landline used to provide. People want the remote connectivity and bells and whistles of their cell phones. Since texting can work on a delayed basis (unlike a voice conversation), people will tolerate some downtime. Overall, people seem to be content with the lower reliability of cell phones. ***** Moderator's Note ***** I doubt most people would be comfortable with lower reliability if they knew that their insurance rates have gone up as a result. Home insurance underwriters pay close attention to the "Fire Danger Protection Rating" of each neighborhood their employers cover: When the percentage of CO-powered landlines falls, the rates go up.

How many of you continue to push antiquated technology to your customers? We should be able to rely on the new technology and the providers should provide backup power so that their service continues to operate in the event of a power failure. If the customer wishes to provide a UPS or other means of keeping his/her hone network devices going in the event of a power failure, that would be their responsibility. Many would be quite OK with providing their own backup power when it is needed. Let us always remember that the chain is no stronger than its weakest link. If their customer provides backup power on their home network and the network goes down when there is an area wide power outage [or local power outage to the area if the provider's facilities] then their customer invests in backup that is only half a loaf towards keeping the network up when a power outage occurs. Of course, I already stated that in a previous post. The last thing I would ever lean on is outdated [or nearly outdated] technology. To Bob Prohaska: POTS is a service that is generally a loop start line in a residence or small business. Loop start (by definition) will always provide power (negative battery] on the ring of the circuit as long as POTS lines are still around. Of course, even those are slowly going away.

The Bell Labs history 1925-1975 provides detailed information on the above Concentrators. The link was previously posted, but I'll dig it out again if anyone is curious. Some writers claimed Bell was too liberal in its use of concentrators and how much they loaded onto them - to the extent that subscribers often couldn't get a call out. Given the service problems of the 1960s and 1970s, I think, in some areas, there is some truth to that. ***** Moderator's Note ***** In Massachusetts, the legislature was more concerned with *where* the concentrators were being placed: mostly in low-income, high-crime sections. They were known as "two-man areas" to the outside plant crews, because there were always two employess on any truck dispatched there. My aunt lived in such an area - the Columbia Point housing project in Dorchester. I lifted her phone once when I was visiting, and heard a busy signal: she explained that it meant there weren't any wires ready to place the call, and that I'd have to wait. I told her that it was unfair and that she should complain. She thought that was very funny.
