11. Applications

12. CONDOR versus ATM Switch CONDOR Cheap Easy configuration No VPI/VCI re- mapping No routing between slave ports Fast protection switching ATM Switch Expensive Complex configuration VPI/VCI re- mapping Routing between all ports Limited or none protection switching

13. CONDOR versus ADM CONDOR High granularity because of ATM High number of independent connections No de-multiplexing Policing Filtering of single connections ADM Fixed granularity because of container structure Limited number of connections DeMux required

14. CONDOR versus HF Splitter CONDOR Active Backward channel available (bi-directional) Support of optical and electrical interfaces HF-Splitter Passive No backward channel available (uni-directional) Support for electrical signals only
