  1. Workshop on CDR (BRBRAITT, Jabalpur) Mediation & Mediation Portal 21ST January 2011 Bharat Sanchar Nigam Limited
  2. Status of migration of SSAs in South Zone Bharat Sanchar Nigam Limited

  5. Online Collection of CDR files from Switches Mediation System FTP FTP FTP FTP FTAM / X.25 Packetware CES MTE CMISE CDOT  E10B  OCB  EWSD  5ESS AXE10 WLL CES : Compact Embedded System (A intermediate device to connect to CDOT switch) MTE : Magnetic Tape Emulator (A intermediate device to connect to E10B switch) FTAM: File Transfer Access Management (A secured network protocol) CMISE: Common Management Information Service Element (a secured protocol) Bharat Sanchar Nigam Limited
  6. Collection of CDR Files from C-DOT Switch The main CDOT switch (MBM) which contains Central Module will generate CDRs and dump into IOP within predefined intervals. CES (Compact Embedded System) device connects to the IOP and collects the CDRS in to CES box buffer (256 MB storage capacity). Unlike MTE box which is directly connected to the E10 B switch, CES box will be connected to the IOP only. CES box is nothing but a PC with Linux operating system having NIC card assigned an IP address. For installing CES devices separate software to be installed in IOP and CES attached PC. Bharat Sanchar Nigam Limited
  7. Collection of CDR files from C-DOT Switch Bharat Sanchar Nigam Limited
  8. Collection of CDR Files from E-10B Switch The control and Memory cards in E10B switch will generate CDRs and write on to magnetic tape drive. At present these CDR files are collected off line into a exchange PC. A device called MTE box was installed by replacing the Magnetic Tape writer for storing the CDR files. The data bus cable which is connected to Magnetic Tape Drive is bi-passed and connected to MTE i.e. MTE is directly connected to E10B switch. File server (PC) IP for ftp MTE also requires an additional PC ( file server) with an application software called “ADRS Charlie” loaded in it for collecting the CDR stream and making the CDR files in regular intervals. Bharat Sanchar Nigam Limited
  9. Collection of CDR files from E-10B Switch Bharat Sanchar Nigam Limited
  10. Collection of CDR Files from OCB Switch The protocol implemented in OCB switches is CMISE which is proprietary protocol of Alcatel. A third party application called Packetware is used as intermediate application in a separate server, where in CDR data will be provided (pushed) by the OCB switches. The CDR data will be written in the Packetware server in a regular intervals (say 1 hour) and the CDR files will be collected from this server to Mediation server using ftp protocol. CMISE Common Management Information Service Element (or) CMIP common Management Information Protocol Bharat Sanchar Nigam Limited
  11. Collection of CDR files from OCB Switch Bharat Sanchar Nigam Limited
  12. Process Flow Duplicate check Transform stage1 Aggregate Transform stage2 N E Billing output CDR File Filter Step1 :- CDR file will be collected from the switch in a scheduled interval of time. Step2 :- CDR file will be read as per encoding rules and CDR structure. Step3 :- Filtration of CDRs will be done here as per business rules, such as incoming calls, prepaid calls etc. Step4 :- Duplicate CDR check follows. Step5:- Aggregation of partial CDRs (if available) will be done. Step6:- Apply the billing requirements and generate the CDRs in billing format. Bharat Sanchar Nigam Limited
  13. CDR Processing Bharat Sanchar Nigam Limited
  14. CDR Processing Validating the CDR fields, error CDR detection & error CDR re-processing. Duplicate CDRs detection. Filtering the certain CDRs as per the business requirements. Incoming calls Transit calls (Calls transferred between two or more switches) FLPP outgoing calls ITC Outgoing calls Supplementary service CDRs (123,124,114,115,118,119) (Password registration, Local, STD, ISD barring provisioning by customer) Fillers (Some additional characters incorporated purposefully by Switch in order to make the CDR structure / block to obey certain rules in size/ length) Other toll free CDRs are not filtered and providing to billing with free CDR usage ID (1004). Bharat Sanchar Nigam Limited
  15. CDR Processing Aggregation of long duration calls (Partial CDRs aggregation). Splitting of CDRs (in Broad Band IPDRs) Detection of all types of call scenarios. Local (PSTN, Centrex, ISDN.. etc) STD (PSTN, Centrex, ISDN.. etc) ISD (PSTN, Centrex, ISDN.. etc) Centrex CUG (by look up) etc. Bharat Sanchar Nigam Limited
  16. CDR Processing Special number calls:- Announcements TOLL Free Toll numbers (full charge to customers) Toll numbers (partially charged to customers) Special numbers like : Police Call centers Ambulance Hospital Help line (Crisis) Kisan Help line …. Etc Bharat Sanchar Nigam Limited
