96 / 136 page ![]() 1996 Oct 29 96 Philips Semiconductors Objective specification GSM signal processing IC PCF5083 9.4.4.4 Handover mode Table 74 shows the procedures to be executed within the DSP for processing of a TCH/FS multiframe in Handover mode. Table 74 Procedures to be executed for processing a TCH/FS multiframe in handover mode Notes 1. Dummy encryption to increment TDMA frame counters (skip Idle + SACCH frame). 2. CM_DECODER_CCH is only called, if the current multiframe contains the 4th SACCH sub-block. 3. Dummy encryption to increment TDMA frame counters (skip Idle frame).
