    HI atul
    i really apologize for my wrong ans.
    actually i had asked this from one engg. who is on contract basis with NOKIA he is from philipines.

    he had given me that answer.

    BUt one thing i want to quote
    might be that flexihopper radio has a capacity of 32 channels but the equipments which we use like RRI card and FIU19E

    regards
    shaleen srivastava
    they have the limioted capacity of 16
    as mukul has quotted about the FIU
    it comes out to be 16 again.

    hi mukul,

    you know that in fxc rr1 unit the max. e1 depends upon the rf plan for that site. it mains if the plan is 16 e1 the number of links will depend upon the fxc rri but sometimes 16 channel cant be use, they are allocating only perhaps 13 channel for the other link.

    2. the rsl and dc reading is synchronized for both of them.
    the rsl is in dbm while in voltmeter is volts, it means the ratio will determine if what label you have for example -41dBm=3.++ something ok
