Fiber run for large campus

[firefoxfire]

A large school is going to link all of its seven buildings together for data via fiber. They have 4 separate Nortel MICS with about a total of 40 extensions. They want to be able to also link all Nortel DN's together.

I am proposing that I centralize one large MICS in the new communications closet.

The question is can I ride on the back of the fiber and have the MICS digital signal send and terminate on some sort of devices at both ends that will then re terminate them back onto copper to a 66 block?

How have you handled this in the past. Is there some new fiber technology now available for voice as well as data. Also I will have several analog lines that need to be send i.e. fax, alarm lines, gate lines etc.. Could I just terminate some 0x16's and ASM's at the distant end and then run the stations off them.

You can use MCK extenders and then use 0x16 modules at the remote end.

thanks. How do these m c k extenders work in concert with the nortel mica cabinet. Do they run over the fiber feed between the buildings?

 

[exsmogger]

As far as I know. I've never used them myself, but I've heard they work well.

So I found this on line:

http://www.phonelady.com/mck-500-2170-000n.html

I am assuming that this should be pretty simple if I understand. This device really seems to act like a fiber "signal booster" or "repeater"? And it one plugs into an available fiber port on the MICS and then that plugs into this device then into the fiber cable that will go underground and then terminate at another building and then plugs into the seconds device and then plug into for example a ASM or 0x16, etc.?

Citel also makes this model as well:

Does anyone have experience with this equipment?

via a t-1, you connect and mck on both ends. fiber won't extend a 0x16 station module. you typically get 24 channels, unless you split the t-1 over multiple devices to connect more than the 24 channels inherently there.

cross connect as many station ports as you want at each location. then respectively those same stations come up.

you will need 2 mck units per building and a t-1 between. maybe fiber has been a solution, but I've never seen just fiber running long distances to extend MICS cabinets.

If we run copper from the MICS what is the max. distance that I can extend the MICS via a standard copper connection to a DN station set i.e. M7310?

I guess this would be the same as if the MICS was in a multi level office building.

I just found this thread. It talks about using MCK's with a fiber run:

i have worked w/ mck extenders and they work well. i've never used them over fiber though. you might want to get in touch with Rickenbacker Communications and ask for Tom. i have worked with him extensively and he should be able to help you with that application if it's possible. website is rickenbackercommunications.com and contact number is on website.. all the best

I was under the understanding than an m c k extender was exclusively used for fiber. Are normally used with copper and how are they installed? Thank you

mck gateways come in 8, 12 and 24 ports. i'm using that setup now with a T1 (point to point) over a network w/ a cisco router.the gateway has to be configured via rs232 port w/ hyper terminal and assigned ip addresses.. one gateway is the extender on site and the other is the remote. depending on the type of connection you're using between sites will determine the equipment you will need. however for each site you setup you will need two gateways.

one extender and one remote for each location. for instance, two off prem sites ( 4 gateways). to connect you need punch down blocks or if you're using a rack 110 blocks or patch panel. either way you come off the 0x16 to punch down block w/ 25 pr amphenol and the same with the extender then xconnect the two. at remote site you come off that gateway w/ 25 pr amphenol to punch down block then xconnect to your stations. the extender at corp delivers your station ports from the 0x16 to the remote via rvp-ip. so in essence there is a lot of equipment involved and can be quite costly.

 

[firefoxfire]

When you say they come in 8,12 and 24 ports does that refer to the number of DN ports that I can send? For example if I use an 8 port extender connected to an 0x16 I will only be able to use 8 of the DN's?

Also, if I stick with copper what is the longest distance I can extend a T7316e from the MICS via copper?

 

[firefoxfire]

By the way what do you think about this device?

http://www.telecombiz.com/mck-norte...mkc-500-2170-000.html?AdID=1245--500-2170-000

 

[atdjr123]

yes, that is correct. you can only send the number of dn's that the extender has ports. currently, i use a 12 port on both ends w/ a T1 over the network. if when you say copper are you referring to the T1?

i think they work great as long as they're configured correctly. but there have been some that have had to have replaced out of the box,so testing b4 install is crucial. you must have a router at both ends if you go over the network. that allows for the transfer of data/voice traffic and giving QOS to voice.

it like anything else, as long as it's up and running it's good. you can go to the website i mentioned earlier or just google mck gateways. hope this helps you.

 

[atdjr123]

i have never used the mck modular extender so i couldn't comment on it. i did look up the specs and it appears that for connectivity over a short distance that this would be a cost saving application to implement.

you need to make sure that you research this device as much as you can and know just exactly what you'll need to have in place prior to install. all the best

Sounds like they are ready for an IP system.
