Hi, I recently applied for a upgrade from 590 NU to 849 NU . after countless calls to MTNL CC and finally to the GM broadband they upgraded my speed to 2 MBPS . I got a call from the engineer yesterday and he told me that he had upgraded my speed and also enabled MAC binding (?????) . as far as i know MTNL does not have MAC binding , right ? . And as i feared when i went home and tried to login i could not connect . the ADSL light and all is steady , but the Pvc0 Circuit says not connected . looks like another round of phone calls for me now $@#*@&#()@#&(&#)I am not sure what the #@#@$$ has been screwed up . Has anybody of you ever faced such a problem ? . any help is appreciated .
