Which is a very DANGEROUS mode of operation, as chances are high it will accept
some phone that has lost signal or is on international roaming! So even if you
have legal permission to operate your own gsm network (such as a test license),
an accept-all BTS will likely interfere with commercial GSM networks in your
vicinity and you will end up selectively denying service to people.
This is punishable under criminal law in probably any country that I've ever
So pleaes use extreme caution and never run an accept-all network on a
non-barred cell outside a faraday cage.
