Dear Developers,

I mentioned earlier that I found a tutorial in which we read that this cell is within the box's serial port.
I found him looking for a RS485 port outlet, and 2x5-pin lines of pins.
Images from the PCB:

IPSEC have read so far by launching tube through a communication gateway through which to get "home location register" information, etc..

Whether there is a chance to even download the firmware via the serial terminal analysis?
Or perhaps to be found in lines of pins USB option?

The presentation referred to the serial port connection just yet to start when you press the reset button four times, then the boot menu to configure the IP address, login data.
