I'm looking at two option for ISDN simulation in my lab:

  1. Adtran Atlas 550
  2. Madge / Picturetel / Teleos / Initia Model 20

Any observations on either choice?

I have an Adtran Atlas 830 and a 550 in my lab for use as a real ISDN
switch and as a frame cloud. Furthermore, I can groom out my DS0s and
Dax them as well as MUX and IMUX the BRIs. There is even a router
built in for use in the frame relay terminations to route between
DLCIs. It is great stuff, but I don't know much about the others. trhe
biggest thing is that the free tech support available is the best.

By the way the Adtran Netvanta routers and switcheds configure up very
similarly to Cisco and I actually am using those in running networks
now since they are a lot cheaper. But for certification purposes you
should still get Cisco unless you need to do some interop work.
