AT&T Mobility Voice Descriptions 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. Conn Date Time Connection date and time- Date and Time the call was connected. Displayed as one column on the Lindline 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.

Page 1 of 15 EFTA00075291 cre AT&T --s- Originating The phone number the call/text originated from. For data records, this does not necessarily mean the number originated the data Number transaction. The network constantly communicates with intemet enabled devices and the data records do not indicate if a customer initiated a data transaction. Some abbreviations are found after a number using 0. 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 = 4t 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 (00)- 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 is 911, 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.

Page 2 of 15 EFTA00075292 AT&T IMEI International Mobile Equipment Identifier Can be 15 or 16 digits. A I5-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.

AT&T AT&T Mobility Common Scenarios Scenario escription 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, ireless and international gateways. ReportAU- Calls that traverse the mobility network. ReportLandline- Calls that traverse the wireline and Voip network. eportlCDR-Calls that traverse AT&T's international gateway. call may show up on one or more report however AT&T has no ability to definitively state or correlate ails as being the same transaction. You may infer any conclusions based on your own analysis of the cords. ET 60:00- Data Usage ata records have a maximum limit of 60 minutes in the CDR record system. Another record is created when continuous data session exceeds the 60 minute limit.
