Voice over IP with Option 11C?

[TomMonger]

Hello,

I had written a while back about replacing 7 OPX lines at a remote location and was interested in a T1 connection.

OK, here's where I'm at: We have a point-to-point T1 which has been used strictly for data from the remote location to the LAN server at our main location. It's basically a bridged system (no server at remote location).

I'd like to utilize that T1 for voice as well as data for those 7 lines at the remote location.

What are some of my options? I don't want anything fancy as this remote location is a manufacturing plant. I've been told I can do IP Handsets, or a BCM system (Nortel), or mini carrier remote.

I can spend up to $10,000 in this project.

Thanks for all the great help!

Our main location has an Option 11C switch

Hi,

you can install a Ip lineside card in the op11c.
this do you connect to your network.
you can then use ip phones like i2004 on your remote location.

Or:

you can install a MIG Rlc card in your op11c.
and install a remote office in your remote location.
To this can you install almost any meridian digital set.

If you need wireless handsets it's a little bit more difficult. I dont have a solution for that.


Your network should be able to prioritize voice before datapackages or possibly bandwith enough to handle it anyway.
Those solutions above are rather tolerant to low bandwith.

I agree with Sennback, We use both of these technologies and they are very stable. I would however look at the 9150. It has ISDN backup and can support upto 32 sets, with full redundancy. It has saved us many times. It connects back to your PBX using the MIGRLC (Reach Line Card) through your WAN. On the 9150 side you setup an ISDN for backup and 911 (for local service). You set the parameters for QOS and whether you want your local users (on 9150) to use the ISDN for local calls or just emergency. Once you get everything setup it is transparent to the users if your WAN fails or QOS drops below the limit you specified. Whats nice about this product is over 1 B1 it makes a data call back to a network port you setup on the RLC. It then creates an IP tunnel using G.729A codec for your voice users. This gives you 8 voice channnels which it then tranfers your users (upto 8)to the ISDN backup. This way your users or customers are never droppped. If you want more detail, get ahold of me. I would take a good look at this product. Also once you get the RLC then you can support single home users too using the 9115 product. These units also have dialup backup. Anyway, A starter package is fairly cheap (considering the technology). You should be able to find an 8 port starter package for 8-10k. Just make sure it comes with an ISDN module. You will only need 1 for 8 users for redundancy. As you grow with the system (more users) you just add DSP's and ISDN module's. Also you do not have to have the latest release of sofware in your PBX either (unless you use the 32 port RLC). With the ITG application you will need at least 24.25. Good Luck

Thanks, Senback!

I am interested in something basic, yet functional. With this lineside card (I'm a novice to Option 11, by the way)... how is it connected to my LAN system? And what equipment is needed, other than the card and IP phones?

Here's my LAN setup: Point-to-point T1 to main location which connects to a 2 port Cisco router (the 2nd port is for another P2P T1 to our main corporate site). From the router, there is a connection to a Paradyne Framesaver. From there, it goes to an ethernet switch on our main LAN server.

On the remote end, the connection simply goes to another Framesaver and then hooks into another switch which supplies the location's few computers.

Thanks for any tips!

Thank you too, BMiles. Your recommended system seems a bit more elaborate, but I'm still interested in checking it out.

This technology is very functional. What is nice you can use it as a basic setup or full blown. Another type we used to use was MCK but we had troubles with quality. I also was a little off on pricing. I have seen it as cheap as 7k for all hardware needed for 8 user setup. If you other questions, just ask. I would be more than willing to explain any one of these technologies in detail with you.
