[Cisco] Help required with ISDN

[Kevork Krozian]

Dear Cisco colleagues,

 I am covering ISDN in Semester 4 and desperately want to do the labs. 
At the moment I can't because of a lack of hardware ( ADTRAN )  for emulation of ISDN functions.

Does anyone know of any ISDN emulation software or hardware that is easy to get a hold of just for one session of labs ??

With thanks
