Keybeep in handheld mode: KBP_R fn da3b da3b 0004 The two overlapping da3b tones (697 Hz, -7 dBfs) are exactly the same as in TCS211 reference. This 2x da3b keybeep remains the same in an active call, and also when the loudspeaker is enabled. With the loudspeaker on, the beeps are very loud! With the headset plugged in, the keybeep changes to: KBP_R fn da0b da0b 0004 This headset mode keybeep still consists of two overlapping 697 Hz tones, but now the amplitude of each single tone is -21 dBfs. Keybeep duration is 120 ms in TCS211 reference, but only 80 ms in Pirelli's version. Switching to DTMF keypad mode: All keys beyond the basic dial set generate the same tone as the # key: TON_R fn bd4c 6683 0000 0001 000a 000a 0005 0000 0005 0000 0005 0000 0005 The above trace was captured in handheld mode. The frequencies are the same as in TCS211 reference (941 Hz low, 1477 Hz high), and the dBfs amplitudes are also unchanged: -7 dBfs for the low tone, -5 dBfs for the high tone. With the headset plugged in, the tone changes to: TON_R fn bd0f 661a 0000 0001 000a 000a 0005 0000 0005 0000 0005 0000 0005 The new amplitudes are -21 dBfs for the low tone and -19 dBfs for the high tone. The duration of the tone is 100 ms, same as in TCS211 reference. Call waiting tone in both handheld and loudspeaker modes: TON_R fn f125 0000 0000 0001 0013 0013 0009 0000 0009 0000 0009 0000 0009 0xF125 tone corresponds to 425 Hz, -7 dBfs, same as TCS211 reference. Call waiting tone in the headset mode could not be tested because of the bug in Pirelli's fw that causes it to hang up calls whenever both headset and USB are plugged in. Busy tone in handheld mode: Same TON_R as the call waiting tone, repeated 3 times. Busy tone in headset mode: TON_R fn f107 0000 0000 0001 0013 0013 0009 0000 0009 0000 0009 0000 0009 The amplitude is reduced from -7 dBfs to -21 dBfs in headset mode.
