I would not claim that Nokia can sell DCCH hands But maybe the thought was GPRS handsets without the unverifiable packet control channel PBCCH/PCCCH (B=broadcasting). That is, handsets using the existing, verified non-P version, BCCH/CCCH. D(ual)CCH was the, for the moment, withdrawn bit which would have made it possible to select which system to use. Once more: 1. BCCH/CCCH = existing, "old", control channel, not optimized for heavy packet traffic. 2. PBCCH/PCCCH, the P-variant,P for Packet, "new" optimized, designed for heavy packet traffic, but very complex, untested, unverifiable at this time in history. 3. DCCM, Dual, a system for "selecting" which one of above to use, avoid a disaster. additionally: 4. No present nor near future cells use PBCCH/PCCCH. 5. Will be activated at some point in the future, when implemented in the networks. 6. The "new" always exists in addition to the "old" - "old" - "old" + "new" The problem: the present version of the standard specifies: 7a. Networks MAY use both systems, just "old" or both "old" and "new" (the "new" for heavy packet traffic) 7b. Handsets MUST use the "new" if the cell uses it, activates it. That is, what operator wants to have tens of millions of old phones with an impossible to test but crucial function, which at some point in the future will suddenly "come alive"?? Noting that these phones upto that future point have been running, tested, approved and verified, on the "old" channel and that the "old" channel will continue to exist also after that point. That is, a perfect ticking time bomb, or actually hundreds of millions of them. continues

"Nokia can still sell DCCH handsets..." Probably supposed to mean BCCH/CCCH only handsets, or with PBCCH/PCCCH inactivated. "But a lack of PBCCH/PCCH functionality is not without a price" Typical soundbite BS, as it is an issue of the situation NOW as well as the situation in the FUTURE. As well as the damage a malfunctioning, unexpected combination of cell and handset can cause IN THE FUTURE.. (not now, because the function will not be active) What is the price (or gain) of avoiding future problems?? ... The rest is just the same, an inability to keep two things separated. Why is that so difficult??? Ilmarinen But it becomes hilarious with "And to top it off, there would be an imminent recall of Nokia's subStandard (pun intended) handsets" The immediate recall would be for those handsets which were released with an untested, unverified "new" control channel. Those using just the old, tested one would just keep on working. However, I'm not sure Benjamin understood how funny he was, as the present solution is to use a recommended subset of the present standard.
