Interpreting Call Detail Records Your response includes Call Detail Records (CDR) either with or without location. Our query results in an Excel file with multiple columns. This is a combined report of calls and messages. Each row represents one call on the T-Mobile network. Some fields only appear in reports with location information. T-Mobile does not retain the content of text messages. Calls made while roaming also do not appear on this report. Entries with outgoing calls to 8056377249 indicate incoming calls that are forwarded (out) to the voicemail system. Entries with outgoing calls to 8056377243 = 805-MESSAGE indicate voicemail retrieval. Please remember that T-Mobile CDR systems natively use Coordinated Universal Time (UTC). By default, that means a day of call detail records are taken from 00:00:01 to 23:59:59 UTC which may differ from your intended time range due to your time zone. If specific times other than our default are important to your inquiry, please submit legal demands with the date range/time frame adjusted for UTC to avoid delay or confusion. We are unable to convert the time displayed in the records to the local time of the handset. The columns present on your CDR may be: a Type of call: callForwarding = Forwarded Call; mSOriginating = Outgoing ‘ell Site location is not available for Call Voice Call; mSTerminating = Incoming Voice; mSOriginatingSMSinMSC = 'ypes SMSc and RCS-IMChat Outgoing SMS; mSTerminatingSMSinMSC = Incoming SMS; moceMobile Originating Call; mtc= Mobile Terminating Call; SMSc = text message; ‘or SMSc messaging, T-Mobile provides RCS-IMChat ® rich content message, multimedia and text ecord of any activity between the equested target number and any other ‘ustomers utilizing the T-Mobile networ for the time and date range requested egardless if the target number currently is/was assigned to T-Mobile or a T- jobile wholesale partner. a [einem [ventana PT a [ettnonie [ventas Pm The final destination number to which the network has connected the call (might be different from the one dialed by subscriber if network translation was applied) Completion Code Completed successfully or Abnormal Completion (network interruption).

Generally, the coverage of a tower is circular and divided in three equal pieces (each 120 degrees wide). Due north is 0, due south is 180. However, not every tower is aligned with the first sector starting at 0. Using the listed azimuth, rough direction from the tower can be calculated for a call. The center degree of the sector's facing is indicated in this field. For example, if a facing has a listed orientation of 90, the center of the coverage is pointed at 90 degrees but the sector will cover traffic from roughly 60 degrees on either side (thus 30 to 150 degrees in this example).
