Data Creation in Local Exchange


Fourth field = two bits (0-99)

If fourth bit is 0 then start L3ADDR at AN side will be 0.the range of fourth bit goes up to 99.if L3ADDR is200 then EQN no. will be 10-0-2-00.if L3ADDR is 489 then its EQN no. will be 10-0-4-89. Also note that the second field of parameter COSDAT should be same as L3ADDR of equipment no. if EQN no is 10-0-5-43 then its COSDAT will be V5ACCID-543. Also note that whenever a subscriber is created its status goes to PLA. This status has to be changed by following command.

CONFV5PORT

By this command the status of subscriber is changed to MBL and then to ACT. Check the status of the port which is made active by command STATV5PORT. Its status should be DIDLE.

  • 5ESS AS LOCAL EXCHANGE
    The testing of AN RAX is done with 5ESS having software version 13.1 and patch S48.

    • CREATION OF AN INTERFACE
      Form 4.5 is used for creation of V5.2 interface. The command used to display the parameters of the interface is “ rddb-v5itf:v5identifier=100: “ here 100 is set as interface ID in AN-RAX.

V5 IDENTIFIER : 00100

V5 EXTERNAL IDENTIFIER : 100

V5 VERSION : V5.2

V5 PROFILE NAME : CDOT-AN

V5 ACTIVE VARIANT : 0

V5 NEXT VARIANT : 0

PSIG LCC : 0

BC USAGE : 00000000000000000000000000000000000000000

L1 RECOVERY MODE : DELAYED

  2. D 011000191 1 S 000124 —– —— —– —— —–

NOTE :

V5 IDENTIFIER parameter set above should be same as interface ID set at AN. V5 ACTIVE VARIANT and V5 NEXT VARIANT should be same as variant ID at AN side. FACILITY = 011000190, here 11 is SM number, 0 is DLTU, 19 is DFY, 0 is facility number. The ID set as 0 and 1 for primary (P) and secondary (S) respectively, should be same as logical ID set at AN side for primary and secondary link . In above example ID for primary link is 0 and for secondry link is 1.

  • CREATION OF V5 LINK
    Form 9.2 is used for data creation of V5 links. The name of this form is EPDLT, parameters for the same are as follows :

SM : 11

DLTU : 0

DFY : 19

FAC IND : 3

TYPE : V5

FACO MODE : CCS

Note: CRC should be deactivated at LE side. It can be achieved by Modifying the parameters “ESCM=CMFAS” in form 9.10. Make sure that this Parameter should not be CMCRC.

  • MAINTANANCE COMMANDS FOR V5 LINKS

  • CREATION OF AN SUBSCRIBER

<rddb-sbldn:dirnr=7911133

DIR NR : 7911133

QUANTITY :……….

LN EQ NR : V 00100P00000

(In case of 5ESS start L3 Addr = 1)

Here, in LN EQ NR ,100 is interface ID and 00000 is the L3 ADDR.The LN EQ NR for next L3 ADDR will be V 00100P00001. All other parametrs of this command will be as per LE requirement. To check the status of AN subscriber :

  • MAINTANANCE COMMANDS FOR AN SUBSCRIBER

To make the subscriber out of service :

<rmv-sub:7911133;

To make the subscriber in service:
