X03: The number of mobile to mobile call attempts. X05: The number of land to mobile call attempts. X07: The number of land to land call attempts. X09: The number of IAM messages received, because of Incoming inter MSC HO attempts. For X01 and X03, following counter will be used. OBJECT TYPE SAE COUNTER NAME NCALLS : Number of attempts to seize a record. OBJECT NAME MTACC-488 This block is seized whenever a Mobile tries to originate a call. X01+X03 = NCALLS of object MTACC-488 in object type SAE. For X05 and X07, following counters will be used OBJECT TYPE MTRAFTYPE COUNTER NAME NCALLS : Number of call attempts. This counter in incremented when an IAM message is received from PSTN ( for an incoming call ). OBJECTS NAMES IEXTE, TRA , IEXSTT : These objects are related to the incoming-terminating calls, transit and incoming external system terminating calls. X05+X07 = NCALLS of ( IEXTE+TRA+IEXSTT ) in object type MTRAFTYPE. For X09 , following counter will be used OBJECT TYPE LOSSROUTE COUNTER NAME NANSW : Number of answers. This is modified counter, which is incremented when an incoming inter MSC HO attempt is made to the MSC. OBJECTS NAMES All MRNR software routes
