Hi,

Thanks for the link, it's very usefull.

Right. Good luck getting the farking thing to actually work.

We had one of those at the Academy I attended. In all the years they'd had the thing, they couldn't get it going. Some investigation on my part turned up that they had U ports on the Adtran, and S/T ports on the routers. Oops! Best part? The instructor had no idea this was the case...

So, for the first lab exercise, we used routers that another student brought in. Worked fine. Later, the instructor scored some U port modules for the existing routers off ebay. Installed them. Went to hook three routers up for the next lab. Only one router had its SPIDs accepted. Swapped routers around, without success -- the problem did not migrate. Double- and triple-checked configuration on the Adtran, and as near as I could gather, it was fine.

The Adtran unit is a fine instrument. Looks like your instructor didn't match up....

It sure looks impressive but.... I checked prices for the chasis and interface cards and I would say it's out of range of a home Lab unless you are John Chambers' (or Bill Gates') son :-) I've seen an ISDN simulator for around $500 new and a 2522 is fine for FR. If you run a training facility, by all means.
