| Column/Field Name | Description |
| Item | Row Number. This denotes a leg of a call or transaction. A leg of a call represents each time the call is processed through a network switch. Calls may go through several switches in AT&Ts network in order to reach the intended party. |
| Conn.Date | Connection Date. The date of the call. |
| Conn.Time(UTC) | Connection Time. The time the call was connected. Time is in UTC. Times is expressed in military time as HH:MM:SS. |
| ConnDateTime | Connection date and time- Date and Time the call was connected. Displayed as one column on the Landline Call Detail Records. |
| SeizureTime | The number of seconds it took to travel through our systems before the call connected. |
| ET(Elapsed Time) | Duration of the transaction. Duration is in MM:SS |
| Originating Number | The phone number the call/text originated from. For data records, this does not necessarily mean the number originated the data transaction. The network constantly communicates with internet enabled devices and the data records do not indicate if a customer initiated a data transaction. Some abbreviations are found after a number using(), They are defined as follows: Dialed(D)-The number that the originating party dialed. Appears in subsequent line of the same row in the Originating Number column.(Note: only appears if the Terminating number differs from the Dialed number) Special Dialing Characters-A=*,B=#Appears as part of Dialed Number(D)Digits. FORWARDED(F)-The number the terminated number forwarded the call to. Appears in subsequent line of the same row in the Originating Number column. ORIGINAL ORIGINATING(OO)-Denotes the number that originated the call before call forwarding was invoked. Appears in subsequent line of the same row in the Originating Number column. TRANSLATED(T)-Indicates if a number was translated to a different number.For example,if the number called is911,then that gets translated to a ten-digit number for routing to a 911 dispatch center.The(T)indicates the number the translation was from,not the number translated to. |
| Terminating Number | The number the transaction terminated to. |
| IMEI International Mobile Equipment Identifier | Can be 15 or 16 digits. A 15-digit number that uniquely identifies an individual wireless device. The first 14 digits are unique. The 15th digit is a check digit that validates the prior 14 digits. A 16 digit IMEI is an “IMEISV.” SV Stands for software version number. The last two digits identify the software version. Only the IMEI of the number requested is displayed. |
| IMSI International Mobile Subscriber Identity | This is a unique 15-digit identifier given to each mobile subscriber and is stored on the Subscriber Identity Module (SIM). The IMSI consists of a MCC (Mobile Country Code), a MNC (Mobile Network Code) and a MSIN (Mobile Station Identification Number): • 3-digit MCC ties the SIM to a specific country • 3-digit MNC ties the SIM to a specific network within that country • 9-digit MSIN ties the SIM to a specific customer |
| CT(Call Type) | Denotes if the leg of a call is an originating leg or terminating leg. Mobile Originating(MO) Mobile Terminating(MT) Service Originating(SO) Service Terminating(ST) A service record is generated when the network generates a leg of a call to reach a service on the network. For example, a leg connecting to the voicemail platform denotes a service invoked on the network and may show up as a service record. See“Item”at beginning of the table for definition of a leg of a call. |
| Feature | This column represents the type of call that occurred as recorded by our network and used for purposes of processing a call on AT&T's network. These are not necessarily indicative of features on a customer's account or the types of services subscribed to. |

| Longitude - A geographic coordinate that specifies an East-West Position of a point on the earth's surface. The Latitude represented is of the cell tower. | |
| Latitude - A geographic coordinate that specifies a North-South Position of a point on the earth's surface. The Longitude represented is of the cell tower. | |
| Sector-A number out of 360 degrees that indicates the side of the cell site antenna used in processing the call. | |
| Beamwidth-A number out of the 360 degrees that specifies the angle of coverage of the RF signal coming from a particular cell site sector. |
| Scenario | Description |
| Many or all Zero Duration Calls | Voice usage reports showing all calls with zero durations in the Elapsed Time ET column indicate calls that were not connected. Numbers such as this are commonly used for routing purposes if there is no associated subscriber. |
| Report Differences | Because calls can traverse many networks, AT&T provides records of all calls that traverse its wireline, wireless and international gateways. ReportAU-Calls that traverse the mobility network. ReportLandline-Calls that traverse the wireline and Voip network. ReportICDR-Calls that traverse AT&T's international gateway. A call may show up on one or more report however AT&T has no ability to definitively state or correlate calls as being the same transaction. You may infer any conclusions based on your own analysis of the records. |
| ET 60:00- Data Usage | Data records have a maximum limit of 60 minutes in the CDR record system. Another record is created when a continuous data session exceeds the 60 minute limit. |
