Hello Everyone, Anyone know of a way of bypassing the 90K audiocodes mediant 3000 equipped for STM-1 interface using line cards and a linux box :). What we are looking to do is replace our traditional ISDN DS3 equipped for voice using an STM-1/OC3 backbone and our own put together linux box. Again, this will be used for voice signaling... Kind Regards, Nick.
Don't you need to drop DS0's out of that STM for signaling? On Sat, Jun 8, 2013 at 9:58 AM, Nick Khamis <symack@gmail.com> wrote:

Most modern gear can go all the way to individual DS0's in a single card without a MUX of any kind. OC3/STM-1 is only like 155mbit. On Sun, Jun 9, 2013 at 10:13 AM, Phil Fagan <philfagan@gmail.com> wrote:

Nick are you trying to run these codecs on linux? On Sun, Jun 9, 2013 at 11:29 AM, Michael Loftis <mloftis@wgops.com> wrote:

Sorry everyone for the delayed response. Basically we are trying to setup up POPS in specific ares. Each POP should be capable of handling 1500-2000 channels or ~60-80 virutal PRIs "please bare with me". Laying down the 80K for Audiocodes 3000 with an OC interface, or even a Metaswitch would be the "big boys" way of doing. Before going any route, knowing our options are good no? Option 1: OC3 muxed down to 84 T1s -----> 7 X 12 T1s Asterisk Boxes --------> IP Option 2: Metaswitch, Audiocodes swtich Michael Loftis said:
If you're doing internal stuff you're better off forgetting about SS7 crap, and just doing IP/SIP over your OC3. No transcoding, you'll get as good or better audio quality, and, more available channels.
I would love to cut a deal with a CLEC or and ILEC to sell us a piece of their network (i.e., place our equipment at their location and cut us a piece of the signaling) but no go. Channels are their bread and butter and they are sticking to it. At $6-$15 per circuit, rolling blackout like the kind you would see in Tikrit, Iraq, no thank you.... To answer your question this is for external. We are trying to place ourselves strategically and offer a hosted PRI solution, along with maintaining our existing customer's SIP<-->PSTN network.
If you're interfacing with the PSTN with SS7 your options are a lot more limited as SS7 support is fairly poor in the FOSS world.
Very true!!! However, there is no one doing SIGTRAN or SS7 over IP that we know of. We are really trying to stay away from reselling someone's service, as opposed to managing our own trunks as we've been doing for over 10 years. Only now we are looking to scale up and market it.

Please elaborate, we are not liking the MUX idea. But we're kind of between a hard spot and a rock :). Phil Fagan said:

Yes but whether we do it by muxing the OC to multiple T1's plugged into *, or using this thing: http://www.gl.com/OC3-OC12-analysis-emulation-card.html I could not resist.... Not sure how many people used this on deployed system. Which brings us to Option 3: Straight OC3 branched out to * with a really cool "Lightseed 1000" like interface on asterisk boxes. No hit for the MUX, not as many * boxes needed.... Life would be so good.... Cheers, N.
