    Can anyone tell me how to configure TMR parameter in the EWSD switch

    #43091 Reply


    Dear, Debasis Chanda!
    1)You should create standard DEST (CR DEST).

    #43092 Reply


    2)Then you should create TMR for that DEST:

    DEST=//new dest value or one already exists//,

    Dear, Debasis Chanda!
    1)You should create standart DEST (CR DEST).
    2)Then you should create TMR for that DEST:
    DEST=//new dest value or one already exists//,
    TMRIPI=//transmission medium requirement and ISUP Preference indicator from incoming IAM message//,
    TIRDEST=//DEST created earlier (CR DEST)//;
    YOU may enter multiple such commands with different TMRIPI and TIRDEST.
    3)Then you should create code point CR CPT with parameter DEST=//DEST from ENTRDESTCNTRL command//.
    After that any call on code point from CR CPT is assigned with particular TIRDEST depending of transmission medium requirement parameter and ISUP Preference indicator parameter of incoming ISUP message IAM.

    Hey pan!!

    Thank you very much. It was helpful. I was working in a interop between veraz and EWSD switch, the PRI won’t just come up. I get physical level generate alarm as the release cause for the EST messages. None of my PRI link is coming up. Can you give me some lead in this??

    Hello, debasis chanda!
    I don’t know what is the EST message. From your post I don’t understand what is the nature of your alarm. Is it physical layer failure? Or LAPD (level 2)? Release and release cause are notions of level 3.
