Hi Sameer,
The decoders of UXCP & TCMON are not given by Lucent to any opeartor . They have the decoder on the Lucent site , access to which is only to the Lucent employees .They just put the output of the trace into that & get the output. However for UXCP decoder try to get in touch with somebody from Reliance Infocomm as they have developed a decoder for that
