PLs tell what could be the reasons. 13th December 2009 at 09:20 #60133 MakGuest Can it happen becasue of transmission issues? 13th December 2009 at 13:38 #60134 PixGuest Mak, yes, transmission or hardware (board) failures could cause sudden call drops. HO failures are probably due to something else. Check your QoS stats to investigate further. Always correlate your drivetests with QoS stats at the same time during the drive-tested cells. -pix 13th December 2009 at 14:32 #60135 MakGuest Thanks Pix 12th September 2011 at 05:48 #60136 akhilGuest In the call testing we r getting data link failure….the level and quality of this is good. no call drop no handover failure ….plz tell could be the reason of data link failure 6th July 2015 at 10:53 #60137 puneetGuest We are getting Data Link Failure in TEMS tool during IRAT Handover when we are trying to make Voice Calls in Dual Mode from Mobile.
