What should I use for analysing E1 signal?

[mimimi]

Hi,

Could someone help me and advice me what HW should I have to build in LV a tool for E1 channel analysing? I need to build a simple tool to receive, send, pass though E1 (2Mbps) signal. My tool should have two E1 ports.

Many thanks in advance.

What I used was a card from GL Communications. LabVIEW drivers are available.

Hmm, I thought about something what can I connect to my laptop. Do you know something like that?

I take it you didn't even bother to check out the web site I provided? Here's a more specific link.

mimimi,

Another company, and probably more cost effictive then GL, you can try is DSPG

They make a system which can be used to analyse E1/T1 PCM streams, it can be remotely controlled from a laptop.

Disclaimer: I used to work for the company, however have not really had any dealings with them in several years. When I was there they had a custom designed DSP card used to simulate/analyse a telephone network (introduce echo/delay etc) on PCM trunks. I wrote a whole bunch of LabVIEW test suites for the, they could probably customise something that would suit your needs.

If you need a contact at the company I could probably dig out an email address.

I did, but I've seen two big PCI card. Sorry, and thanks again.

nrp, thanks for info

No, you did not look at the link if you missed the USB solution.

hi, 

Can E1 signal (2.048MHz) be interfaced with some  labview fpga module?
