Corona, CA | Why are they so big? What is in the cabinets that it requires them to be so large?
Meanwhile, if Sarah wants her stove, she need only donate a few hundred thousand to her state whores politicians.

Glendale, AZ | Cards, electronics, and wiring. Maybe even air conditioning in a hot state. The one to the right is a cross box and was probably there already.
Just moving the CO closer to the houses. |

I can tell you whats in there! From the central office is fiber leading up to this VRAD. Inside the Vrad is about 4 cards with 48 ports on each of them. (each customer is 1 port) If a customer cannot get a broadband signal, the tech needs to visit the VRAD to troubleshoot. This is what you are looking at in the picture above. |

Multiple blocks take up all the space.

The second box next to it is the crossbox holding all the pairs and copper for voice. |

hiatus | Those copper pairs have to terminate in the VRAD somewhere... So, there have to be punch downs inside of the VRAD as well.

Prove it...
Save the Internet Time (NTP) service, use the pool. |

That's not what's inside really.
The entire bottom of it is battery. You need a rack for inverters. That's a pretty decent chunk. Then you got about a third that is electronics and then one whole side is protection and splices.
Though I never went into one that's what's inside a remote generally. |

NOT Texas! | reply to bmn
Nope. The binding posts are inside the SAI?B-Box next door. The space is taken up by back up batteries and rectifiers, environmental equipment and the cards. Nothing for the subscriber is terminated in a VRAD. |

hiatus | How does the VRAD interface with the copper portion of the network then if none of the customers copper is in the box ?

| A splice is physically made from the coil block to the crossbox. SOP on RTs. then when provisioning the service you run the voice in series to and then back from the box.
600 pairs can be spliced/wrapped and take up little room. |

I knew this all along, but the comment about them being as large as a traffic light controller gave me a thought as to "hmm, yeah, why are traffic light boxes so darn big"... I know in those they don't have punch down blocks...

You don't have punchdown blocks in VRAD's.
Funny what you "know". |

Actually, the 48 port VDSL2 cards are not being used yet AFAIK, they are still using the 24 port VDSL cards (software upgradeable to VDSL2). Even with the 48 port cards, you are only going to have 24 users per card (assuming every customer will be using pair bonding), as those cards can do pair bonding (2 ports/pairs per user), and my guess is that is the only time they would use them, or I could be wrong too, I don't really know, just my 2 cents. |
