All Bell. I can tell you that an RBOC C.O. makes most IT or computer rooms look like dumps.
FWIW, when times were slow we would actually *armor all* the vault cables as we went along checking bonds / grounds.

There is a certain smell to C.O.'s which is universal. It's not a bad smell, just unmistakable. It's almost pleasant if you don't have to be in there every day. Anyone who's been in one knows what I mean.

The best was being in there on Mothers Day before the digital switches went in. What a noise! The clickety-clack has now been replaced with the droning hum of fans (much like server fans). The new switches are tiny compared to the old. Many offices still use the old "cosmic" side of the frame with the new switches, which is laughable since it outsizes the switch it serves 2:1.

The one that is totally false is when he claims that they're "hardly noisy at all."

Todays CO's are incredibly loud. There is no debating that. The Nortel switches hum like mad, and the Alcatel backbone is horrible. Probably the worst of all is the cooling fans of the Alcatel 1000's. In a moderate sized office these DSLAM's were lined up 4 to 40 bays deep, and had 2 to 3 fans per bay!

A close third are the Cisco GigE switches... the 7600's I think? One local tech even called in OSHA because he felt his desk was to close to the Nortel switch.

Two seperate power feeds with wet-cell batteries that would power the entire building for 8 hours and a deisel generator that would power the building indefinitely.

Since DSL does not go through the switches, you may find that your voice may get better, or they could end up FUBAR'ng it up in the upgrade.

The talk path thru the 1AESS is all metallic. The talk path is set up using reminant reed switches and copper junctors, and you can indeed hear the clicks during call setup and especially during call waiting and three-way calling. The operation of all those metallic paths is under computer control ... probably an AT&T 3B2 processor retrofit.

As for voice quality, except for the transient noise, the analog ESS voice quality should be as good as or better than a modern digital switch. The best that a G711 digital connection can be is only almost as good as a *properly operating* analog circuit.

However, if you are served by digital subscriber carrier from the analog switch, that adds an extra analog-to-digital conversion that can degrade quality ... especially analog modem performance.

Dennis

If the office has a traditional switch it will be 48 volt based and I would guess that applies to 100% of ILEC offices under NEBS.

Cell sites are a mixed bag many of the older sites are 48 volt based while the x gens seem to be all 24 volt based.

Another thing few relaize is they are using the same layout standards. As such a CO tech could go to any ILEC CO and work using only the WORD document as a guide.

And, yes, you're right, it usually is quite difficult to colo in a telco central office.
