Well there are simulations for devices like RX01 and TU58 and serial
papertape-readers / punches, but these are all standalone programs mostley
on peecee platforms. Has nothing to do with SIMH, nevertheless very cool.

I have never heard of any simulation of this...
I think this will need a quite powerful computing device to provide at
least something near the performance and troughput of the original device.
Those embedded CPU's are mostley well optimised for speed... 
Wouldn't it be easier to get an used 2500 to play with?

OTOH there are simulators for 68K processors (not under SIMH), see eg:
http://www.cse.sc.edu/~jimdavis/Tools/wism68_simulator_for_motorola_68.htm
one could try to get a 2500 firmware run on this, I think this requires at
least detailed knowledge of the 2500 HW-architecture and some kind of
permission from Cisco...
