Campus install

[RikRodgers]

I'm pretty sure I know the answer to this one, but I'm hoping someone out there knows something I don't.

I've quoted a local church / school with 3 buildings a new MICS and MCK fiber extenders to tie the buildings together.

Problem- they want to go with the phone system, but don't have any conduit between the buildings, and don't want to pay the money to have it installed.

They're currently using a P to P wireless antenna to feed network, and want to use that for the phones, too. VOIP.
The gateways I've priced out to feed 26 extensions to the other buildings are more expensive than the buried conduit.

Does anyone know of any way to actually extend a fiber mod over ip? If not, maybe we should put our heads together and design one.

Thanks.

No possibility of going aerial?How far apart are the buildings? Are they connected in any way with covered walkways.

If there is a broadband connection at each building I'd consider installing a BCM with VOIP extensions at the remote sites.

Thanks, guys.

Oldpolelineman- The city doesn't want us running arial.

Exmogger- Yeah, I think voip is the only way for these guys. I was just hoping there was some way to keep them on a MICS. Gateways on both ends will crush their budget as much as the burial fiber.

I had the same situation and went with BCM50 with 5 IP sets riding on 2 wireless bridge; they work fine with low volume traffic on H729 VAD codec.

I suppose the reason codes wont' let you go aerial is somethin like this maybe?

I guess we have been luck in not having restriction in this area,but I can see how it could get out of hand.

I think your best bet is going to be a BCM / BCM50. In many cases, the BCM will price out similar to the MICS if you don't turn on all the bells and whistles. To help offset some of the costs, perhaps locate some refurbed digital and IP sets since this is usually the highest cost of the project. I know we all want to sell the whole enchalada, but sometimes taking a small hit in stations from a third party gets the system sold with everyone still smiling. Watch your QoS over that wireless. Hopefully they are not pounding it with computer data on a regular basis.

To answer your original question, I know of no way to extend the fiber modules over IP.

Rik, we have some Water Companies and Golf Courses, where the maintanence buildings are fed by Wireless feeds for data and VoIP. BCM/BCM50 both work to run remote IP sets. Works great, but VLANs and QoS are a MUST.

Thanks, guys. I'm looking into the voip solution. The only reason I'm hesitant is that the link they want to use is a wireless connection they've had trouble with in the past, and once you tally up the cost of the voip hardware, they'd be really close to the 14,500 the buried conduit would cost them.

Yes, I could go refurb, but we offer a 1yr warranty on all our equipment, and we've gotten stung that way in the past.

 

[exsmogger]

Most Nortel resellers offer at least 1 year warranty on refurb equipment, and a lot offer 2 years. I'd check out the refurb option.

I would try to convince them to go with buried conduit. If the cost for wireless is almost the same or even more as conduit, and QoS is not as good, seeing that they have had problems with wireless, I would point this out and tell them that conduit is the way to go. I would also convince them that they can also use the conduit for future upgrades as well, not only for telephone but for data as well, and maybe that could become more of a selling point for conduit.

Also- question-

When were the buildings approx. built? Many older buildings (1950s-early 1970s) were built with more block/brick and would make it hard for wireless signals to pass and still have a high QoS. This could also be pointed out to them and maybe make it more of a selling point for the conduit. Either way, I think conduit is a more firm solution. Then you could do the MICS with fiber extenders. I would be surprised if they were newer buildings (1990s-present) with no conduit in between them.

We have a County government setup with a BCM in one building and a MICS with a gateway in the other about a mile away.

There is a CDP network between them across a point to point wireless link that has worked flawlessly for several years.

Telmar (formerly Precision) offers two year warranties on their refurbished equipment and we've had good luck with them.

jpanzer- I prefer the fiber in conduit, too. The buildings are all turn of the century- the last one, not this one.

Thanks, all for your input. I'll let you know how it pans out.

I gave OldPoleLineMan the wrong links above. Should be these:

[jpanzer]

Not a problem. That explains what I was thinking, that it was an older building...

Good luck.

Techie29- We had a few pictures like that pinned up around our warehouse years back from Beiruit.

Kinda made you feel good at the end of the day. No matter how bad the work was that you did, you knew someone was worse.

Have you looked at the MCK gateway products? I used a PBX Gateway and a MCK 6000 remote office to provide 8 stations remotely from an existing MICS via a T1 network (your existing network would work)

Yep. The remote location has 26 ext's. The configuration of the gateways is where I'm a little unsure here. Can you go PBX Gateway to PBX Gateway? The only way I've used these in the past has been to feed multiple single sites- people working from home. I know I'll need 2 16 port PBX gateways at the KSU, I'm just looking for the most efficient way to do this at the remote side.
