Modem reset with event "ADL_INIT_POWER_ON"

when I try to send data to internet, about 1500B on 10s, and I use timer for sending data repeatedly.
But, my modem is reset continually with InitType of ADL_main function is ADL_INIT_POWER_ON. I can’t bug this reason.

19 viewer and no reply, what’s happening?

It means that none of those 19 had anything to say!

There isn’t really enough information to be able to debug this remotely, I’m afraid.
