. `Burst`:

)TS ( TDMA .

Note: the duration of a time slot is 577 _s according to the definition. These 577 _s are not given in descriptions of the transmit power of a burst and often irritate readers of literature on GSM. The time domain of 542.8 _s shown in fig. 8 and 9 (corresponding with 147 bit, also known as useful part) is the range where transmit power is required at a constant power level almost as a information transmission platform. Together with the time ranges from the flanks (increase/decrease of power) of a maximum of 28 _s each this gives 598.8 _s and is thus slightly longer than the duration of the accompanying time slot. The two 28 _s are however only time maximum limits for the flanks and interference from burst of successive time slots. They are reliable when the power is appropriately low so the duration of the technically realized burst coincides with the defined duration of a time slot in the 1st approach.

With base stations the dynamic range is 70 dB, with low power (mobile phone: 2.5 W) 36 dB. The set tolerance masks for transmitting a burst from a BTSE are shown in the following diagram.

Tolerance masks of the TDMA burst

` ` Normal Burst: .

Page 4 of 4

The normal burst contains : _ 2 x 3 bits as tail bits (TB); _ 2 x 57 encrypted data bits which carry the actual information _ 2 x 1 bit as a "stealing flag" which tell the receiver that data transmission is being interrupted briefly and signaling data is being transmitted instead of useful data (or vice versa). _ 26 bits for synchronizing and problem detection (training sequence) which allow both the BS and the MS to synchronize themselves to a burst and allocate the data bits exactly. Distorted or incomplete received signals can thus be reconstructed.
