Re: VZW Home Phone Connect said by 49528867:No if it is copper it will be a point to point DS1 between the site and the MTSO usually being a DS1 to a CO and from there muxed up to fiber
I've never seen a DS1 to a cell tower that did not pass through a CO at some point. Almost always goes to a local CO where it hits a DCS before heading on to where ever it's going. Then again, I've only dealt with cellular in a rural setting, where thousands of square miles and several area codes are covered by a single MTSO. And I've been out of that business since 1999.
But in the case were a line, either DS1 or fiber is leased from the telco or a third party, there's going to a POP somewhere that could become vulnerable.
I guess what I'm saying is nothing is 100% fail proof  |

Almost always goes to a local CO where it hits a DCS before heading on to where ever it's going. But a DACS while commonly referred to as a switch is really a mapped test point device and unlike a CO switch has its inputs and outputs nailed up and unless the mapping is changed it really does little switching what so ever.
For the most part the only non-mapped switching in say a 3/1 DACS is to take a DS3 break it out to a DS1 level and then allow those individual DS1’s to be connected to a test-point for A or Z end testing.

Some parts of the network are, but certainly not the entire thing ...
Typical HLR uptime is somewhere in the 99.99999 range or so. |

I think Bell tried to have five nines uptime at the customer premises. I don't know what the uptime of my wireless carrier is, but I can't remember the last time I was unable to make a phone call. |

| In the olden days, "Five Nines" wasn't a try, it was reality. Up until deregulation, quality and customer service was of the utmost importance (contrary to what a lot of people on DSLR will say). If it took 3 hours of over-time or 1-1/2 day to restore a single customer, so be it. Breakup (divestiture) "slit the wrists" of that mindset, and TA96 was a 50 yard, 30-06, "headshot" to the idea that quality work was an essential part of providing good customer service.

I can. It was about 2 weeks out of every two months. That's how long it took Verizon to get the report and schedule the repair. Even when it was up the hum and static sometimes made hearing impossible. We went to home connect out of desperation and so far it's been great. |

That's absolutely right. My first wife and many of my classmates went to work for C&P out of high school. I assure you they didn't have the rabble that evolved when C&P became Bell Atlantic and then Verizon. |
