   Most likely a Nortel (now Ribbon) CS-2000 as the core with a Gx or MGx   
   media gateways. Not as good but with significant power +consumption   
   savings.   
      
   I still work with the 5ESS daily but it is indeed becoming a relic of   
   days gone by. Most of my smaller deployments have been replaced by   
   either Cisco or Ribbon solutions and the larger ones are being   
   migrated to N4E (the updated 4ESS) when acting as a tandem or for end   
   offices services are now with the Metaswitch or Sonus solutions.   
      
   As much as I love the DMS it is like a black and white television in a   
   color 5ESS world. Someday I will be running a VCDX with DNUS in my   
   basement.
