Requirement of Hardware for CDR collection and provisioning SWITCHCARDCABLE OCBACV 11 3BW01585 GL cable (ACV11 to IRP box) 3BL01939 HL cable or 3BL02204 JA cable (IRP box to Router) 5 ESSUN 582 B ED5D500-21-G72C ( UN582B card to Router ) AXELIU 4 TSR909031 (Card to Router) EWSDLAU B & LCU B S38228Z149A300 (Card to Router)

7. Requirement of hardware (contd) E10B:- MTE will be mounted in the OMC. Requires 2 nos. of -48v dc 3 pin sockets in the bottom shelf of the OMC C-DOT:- CES will be mounted on IOP. Requires 2 nos. of -48 v DC sockets near IOP NEAX & FETEX:- MTE will be used. The power requirement is 2 nos. of -48 v dc. The mounting details will be conveyed shortly

8. Status of CDR collection In respect of E-10 B exchanges, the CDRs are collected using MTE in Golconda Exchange 17-01-2008. In respect of C-DoT exchanges, the CDRs are collected using CES in Medchal exchange on 18-01-2008

10. CDR collection at NT switches For testing the CDR collection at NT switches, a server was temporarily installed at Charminar EWSD switch room. The following exchanges were connected to this test server and CDRs were pulled successfully – –EWSD Exchange, Charminar, HTD –5ESS Exchange, Vanasthalipuram, HTD Testing the CDR Collection Process is in Progress at the following exchanges –OCB Exchange, Kavadiguda, HTD –AXE Exchange (IN 56), Annaroad, Chennai –AXE Exchange (IN73), NTB TAX, Bangalore

11. Changes in CDR Formats C-DoT Exchanges are required to be upgraded to 2_2_1_9 version. Instructions from MS cell already issued. OCB exchanges require Variable CDR Format (TLV). Field trails completed. 5ESS exchanges are to be upgraded to SU11. Some additional optional fields are required to be added in EWSD CDRs

12. Transmission requirement E1 from each exchange router to Central and Aggregation router STM 1 link between Aggregation and Central routers

13. Action to be taken by SSA Channel allocation for E1s from LE routers to aggregation routers as per the SSA WAN diagram Assessing availability of the cards and cables for X.25 protocol enables ports and procuring the same either directly or through MS cell. The requirement of cards is to be assessed by considering the present utility and CDR requirement.

14. Action to be taken by SSA Network diagram of existing CSR network marking clearly the replacement of routers etc., and new locations as per the provision made in BOM. Instruction to be given to the exchange in- charges for allowing the HCL personnel to install the routers and extending the all possible help in making power sockets available, in laying of data and power cables etc

15. Action to be taken by SSA Up gradation of the existing PCs to the requirement of CDR project ( 256 MB RAM, windows XP) Switch upgradations as required –C-DoT 256 Boards to be replaced with ANRAX –C-DoT SBMs to be converted to RSUs –CDR format changes as required

16. PCs & Antivirus status All PCs should have Win XP or Win 2000; Should have a browser. All SSAs should ensure valid and updated anti-virus running on PCs If necessary old PCs may be replaced with New PCs of required config All Dumb terminals working for DQ, FRS etc should be replaced with PCs SSAs have to procure work station PCs for any newly planned CSCs If any CDMs/Touch screens are provided in the SSAs, details about connectivity, configuration, Integration of software etc may be intimated.
