Pix,
There is a similar SI5ter which is sent over SACCH and i believed this is what the bts will send in the DL during dedicated mode, but i have not seen this message during the drive. I will check on #1 if the message was sent on SACCH, but this is strange since 3gpp is specific that si2quater will be sent on BCCH. I am about to believe on #3 though since there are lots of issues regarding TEMS9.1, the reason maybe why ASCOM released TEMS10 in lesser waiting time than usual.
Thanks for the reply.
