Building to Building MX One Connection

[Monrovia]

Hello all,

I would like to get ideas about the connection between two buildings.
Here I am using MX ONE system which has 5 LIMs all connected using PCM links. Also using IP Phones in it. Now my company purchased one more Building near by but it is opposite side of the road. So
which is better way to provide connection to the new building, which may use aprox 100 extensions.

Installaing a new PABX and connect it by tie ups(E&M) with direct cable?
Install New LIM there and connect using PCM Link?
both these need to trench the road,which is not good, as the roads may cut any time by govt authorities for like water,telephone, etc

Or is there any other way using IP Network? in which ip can use wireless network - WAN.
If this WAN can use, do i need another PABX like BusinessPHone 250, and will mx-one support connecting together?

So I need ur suggestion...this is very urgent.

Hi

I suppose that the users in this new building will need to reach the existing LAN for their normal work with their PC?
So why don't you use this network to provide telephony overthere?
It is up to you to decide if it will be Ipphone, Ipnetworking or LIM remote over IP; to my opinion, it will only depend on the cost you will spend to use the same network for voice and data and the solution that you choose in the new buidling (remote LIM, new PBX or simply Ipphones).

Best regards

hi fouesnant

cost is not a problem. but reliability is the main issue. if i use the LIM using PCM Link or E&M, and there is some work in road, the cables may destroy.

yes, the new building will use pc with them and for that WAN is going to install - wireless LAN. can it be shared for voice also?

is there IP Trunk facility in this MXOne? i mean, H.323 ip networking will help me to solve this problem? so that i can use wirelss LAN/routers and connect that LIM?

Ha! If cost is not a problem, then you have no problems! ;-)

If I was in your situation, I'd go with adding a LIM to the existing system.

Are there any companies who do directional boring that you can utilize? Some of these systems allow you to go down well below future potential excavation and the bit can be directed to almost anywhere you want it to on the far end.

You can then pull in your own cable facilities.

There are also some pretty reasonably priced line-of-site wireless systems available these days.You can run your network over that and provide PCM links via a TDMoIP device or circuit emulation......if you have to trench, you can put one of these in as a backup if the cable gets cut.

I wouldn't recommend trying to run IP trunks or other voice services over a wirless LAN.

Good luck,

Dave Strang

thank you for your suggestions.

direct cable - using trench is not a reliable solution. cause any time the roads may dig by govt authorities.

i would like to use some other solution using wireless.

Hi all

I do use Wireless LAN for one site. LIM 1 is in one building connected over Wireless lan to GS. So far (almost 10 years) no problems.
Of course you have to be precautionous regarding the wireless point : no trees, or other obstacle that might cut the beam.

I also do use WAN connectivity for a 3 LIM system with duplicated GS; all LIMs are connected over WAN and on GS on one site and the duplicated GS on other site; so far so good.
The customer has WAN security in case of WAN failure or road excavation (2 WAN provider and 2 WAN access)

Best regards

For you case, if the cost is not a problem, I would use a mix on theses 2 solutions : add a LIM to your existing system with a Wireless connectivity and a WAN connection

 

[Monrovia]

thank you very much for the suggestions!

can I use wireless LAN with another BP250 over there with H.323 IP Trunking faciilty?

hi fouesn

wireless lan - how much is the distance? will it work for 200mtr without any obstructives like trees? i think its proportional to the antenna power. isnt it?

ok.

what technology is using to connect GS thru wireless LAN? any special cards?

 

[whosrdaddy]

we use Airmux-200 from RAD for this purpose. distance can be long (depending on antenna type :yagi, etc...).
you just get E1 as input / output. so you can put GS links on it (no special boards required) or standard 2Mbit PRA.

Cheers,
Daddy

Hi

The distance that I have between the 2 wireless point are about 500 mtrs.
AS whsrdaady say Airmux is a good product that you could use and based on the antenna type you select will have more or less distanec between eachpoint.

 

[Monrovia]

thanks for all your replies

according to your suggestions, let us decide

If you cann't afford Mini-Link then there are cheaper Optical Line-of-sight solutions (ie. Laser).

You really in Monrovia ?

Hi Monrovia

Easy, use WLAN, you know what happens to lazer beams in Monorovia rainy and misty weather!

And then You can look at a Ethernet to E1 converter

Then you can use PCM or Qsig, if its a BP you can use QSIG IP or E1
