Holy FXS Ports....
I like!
I'm assuming thats 16 FXO and 8 T1's pictured?
Did you run each switch back to your core?

each switch is connected to core in main building. As for the ports, I believe you are correct on the count. This is also the Dmark for the campus voip system. There are several other gateways across campus for other analog phones.

Sweet!
Are you using CUCM, or you just using their equipment for something like Asterisk?
Nice setup, hopefully when you cable it up, it stays just as clean

I'm pretty sure that those are Cisco VG224's.

next time I'm thru there I'll snap a few pics. Nothing fancy just 110 blocks on the wall.

Ahh ok, terminating fiber is fun too

I thought they were 2431-16FXS at first but they are missing the WIC slot so they are probably 224s. We used to deploy the 2431 as a CPE at a customer site. We replaced them with Adtran TA900s because they are cheaper, have free support, free AOS updates, easier to troubleshoot, and they are more flexable.

That frame looks like it might be in decent shape and not all messy.

What's up with the weatherproof cabinet inside the building?

I was just about to ask the same question...

If I had to guess... air conditioning. I've seen that done a number of places. (mostly in closets.)

yeah ok but that doesn't really solve the problem. once you hvac a box like that in another space, you still need to be able to deal with the heat removed from the interior of said box.

Why all this for an obsolete technology? Why not just do VOIP directly and get rid of the phone wiring altogether?

So it was cheaper to put that cabinet in than fix the roof. Ok that makes sense.

That roof must have been expensive to fix because a properly done up box like that is 7 to 10 grand easily. Of course they probably cheaped out on that too so that's why it might likely be the reason it is there.

Lack of suitable wiring (CAT5) in the building to the phone locations would be my guess.

My second guess would be that it's probably cheaper this way, than to purchase hundreds of VoIP phones to replace the existing POTS phones.

But POTS phones just aren't the same... They don't have all the features of the VOIP ones...

No, but they can get close enough that a digital phone system is a viable alternative. Beats rewiring and replacing all that hardware.

You wouldn't have to rewire very much, as any desk would already have ethernet, and the phones can pass it through to the computer via their own internal switch.

Any large org will *NOT* mix voice and data traffic to the desktop. Also, how are they going to power all those phones? What happens to desktop connectivity when the phone fails, reboots, whatever? Very few voip phones are gigabit -- and the ones that are, aren't cheap.

If you have a large analog phone infrastructure, you don't rip it all out overnight.

[I work in an office with 10 people, and I run voip is on an isolated network.]

Why not? It's all Ethernet, it's all IP. Power them through PoE switches. Most desktops in organizations don't use gigabit.

That's great that you run it on a separate network, but that's not really necessary.

Do those Cisco systems hook up to a wholesale SIP provider just like any other VOIP solution? I'm sure they could hook up to the local phone company, but that wouldn't really make any sense cost wise once you're on a VOIP system...

Thats a good question. This campus has ALOT of analog phones. I guess it was cheaper than licensing all those IP phones. The VOiP upgrade was mostly to replace the dying Rolm PBX. Its a seasonal place and the IP desksets were placed in administrative offices. There are also ALOT of autodialers for remote building monitoring systems. There are additional VG's feeding analogs at the other end of campus as well. The old PBX was having trouble feeding those distant phones. Fiber was pulled to feed those VG's and all the distance problems disapeared. And yes, the cabinet was cheaper than fixing the roof or moving the telephone room. It weighs about 300lbs empty.

Oh so they did a few IP phones, and then the rest through the analog gateways?

There were probably close to 200 IP phones deployed.

I don't mean to sound rude, but are you new to IT? It makes a heck of a difference properly laying out your network. As already mentioned if not for the fact of having an additional failure point of the phone as a switch or the phone not being gigabit. Also not having all the extra load on the data network. QoS can only do so much. Also unless his campus was new I doubt it's all wired with a minimum of cat5e. Running cable throughout campuses is not simple or cheap. All the switch gear with PoE is pricey. Also quite a few organizations that are clients of mine or I've worked for use gigabit. The cost of IP phones are also tenfold over digital or analog.
