Kannel encodes the DCS using the coding, mwi, mclass, etc fields. But as you can see at doc 23038 from 3gpp, there's two alteratives for some combinations for example, a 8 bit class 2 message could be 0x16 or 0xF6.
if alt-dcs is unset, 0 or 2, kannel uses 0x1f. if set (1), it uses 0xF6 some modems just use one form, and for example, emi2 can use any, but a sim-toolkit message in emi2 demands that dcs is 0xF6, not 0x1F, even if 3gpp docs say that you could use both ----- Original Message ----- From: "Steve Rapaport" <[EMAIL PROTECTED]> To: "Bruno David Rodrigues" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Thursday, March 14, 2002 6:20 PM Subject: RE: DCS and PID for 8-bit SMS > Thanks! > > One more thing (from your docs:) > > I know what a DCS is, but what is an Alt-DCS? > > Is this as an alternative to specifying MWI, MClass, > etc. manually? > > Or is it something else? > > ____________________________________________ > Steve Rapaport > CTO, A-Tono > Via Amedei, 15 - Milano 20123 > Cel.: +39 348 6431573 > Fax : +1 617 687 0415 > > >
