Hi,

I would like to test a device on a BRI line. I would like to hook up
two modems back to back and inject delay up to 1.5 sec. to simulate a
satellite. Can anyone recommend a device for such a test?

Any ISDN line emulator will work for the connection, I might still have my
Teltone ISDN BRI line emulator, I'd have to look, and would be willing to
part with it for a fair price. As for induced latency, try shunra.com I'm
not sure about ISDN but they make a great LAN/WAN emulator.

I used to do a lot of ISDN BRI/PRI working for PictureTel and now do a lot
of data and voice, and I can tell you that 1.5seconds latency will kill
almost any application. One issue with satellites I saw at Pictel was when
we added a second satellite hop the latency went over 450ms and the
connection dropped.

Good luck

The only thing I guaranty about my free advice is that it's mine and it's
free.
