PSTN Simulator

fid500

Hello

I am trying to build a home lab for CCVP and was wondering if there is a way to simulate PSTN. I checked on ebay, they have some boxes that go for over $2500 that can simulate BRI, PRI and T1 but that too much for me. I was hoping for something under $100.
Could you please share your experiences on how did you go about using PSTN?

thanks

Adtran atlas 550 with T1 and Pri interfaces, 8fxs and 4 ISDN BRI U interfaces

Multiple Cisco MC3810's with T1, FXO and FXS interfaces.

When you search on eBay make sure you search for "pots simulator" "pbx simulator" and "pstn simulator"

I started with a PBX Simulator (there's some for $30 right now on eBay) and then got the Ascend/Lucent MAX 6000. There are also the Madge -- so you might want to also search for "wan switch." There were a few Adtran deals a couple months back (around $250-$350) and there are some MAXs & Madges around $500-$800 on eBay right now.

I've also got the 5 MC3810s. They are great when you first start out because of the selection of ports you can get, and they can be cheap if you shop for them and wait for a deal. Then you can also use them later as your PSTN cloud if you add more current voice routers to your lab.

Hello

I was checking ebay and find this router for a reasonable price, but I dont know if it needs more modules. Could you let me know if this router is sufficient for CCVP or will I need to buy more cards for it?

One of my 5 is in that configuration -- with the 2 T1s. Couldn't see the memory, but it looks like 8 meg flash and the 6 DSP module.

When you're starting out, the AV6 Carrier and the FXS, FXO, and maybe E&M daughtercards are more useful, and you can have a single T1 with that -- so if you had 2 of these, then you could have "2 sites" and hook them up back to back via the T1s.

You can find some MC3810 info in these threads:

Guys, please, give an advice if it's possible to use Cisco 2801 router as PSTN.

Blimey you've dug up an old post here mate!

shodown

yes you can use it as a PSTN simulator, you may come up short trying to use it as a frame and PSTN at the same time.

Some of the legacy routers work just as well...the newest IOS are not critical for a PSTN/WAN simulator, I'm using an old 3725, with 6 PRI & 8 serial.

sacredboy

Thank you guys for you responses. Please be kind also to advice the necessary modules for my 2801 in order to simulate PSTN.

Man, we miss mikej

OK guys it seems that for PSTN simulation the following modules are required:
WIC-1DSU-T1-V2
VWIC2-2MFT-T1/E1
VWIC-2MFT-T1/DI

I'd be grateful if someone could explain the purpose of each module.

shodown

to be honest with you if you don't know the meaning for the cards you aren't ready to built a PSTN simulator it would just beat on your brain.


VWIC2-2MFT-T1/E1 That is a voice/network module. You can use it as a PRI Voice T1 or Data T1.
The WIC-1DSU-T1 is a data T1 that you can use for frame-relay or just stright data T1
