Re: [Openbts-discuss] First installation problems

[Balthasar I. <ba...@in...>]

This is a bit confusing. So according to the book on p68, the default
GSM.RACH.AC is set to 0x0400, which it is:

OpenBTS> config GSM.RACH
GSM.RACH.AC 0x0400     [default]
GSM.RACH.MaxRetrans 1     [default]
GSM.RACH.TxInteger 14     [default]

This advertises that there is no SOS calling on this beacon.

yet my phone when selecting the OpenBTS network manually says "SOS
Only" - the exact opposite. Is my phone seeing the right network?

None of the registration messages are being sent to it, neither the
registration nor rejection messages.

?
