B-1 B Glossary.
B-2 Glossar y ARFCN Absolute Radio Frequency Channel Number BCH The BCH (Broadcast Channel) is a beacon which is always turned on so that mobile can look out for it when trying to find service. A useful BCH always carries information in timeslot 0. The BCH ARFCN has to be activ e in all timeslots to allo w mobiles to synchronize to other cells.
B-3 Glossar y Burst-by-Burst Bit Error Rate The Burst-by-Burst Bit Error Measurement makes use of a ne w loopback path within the mobile to calculate the equiv alent Class II BER. This measurement is 5 times faster than the con v entional method. This is also sometimes kno wn as Fast Bit Error Measurement.
B-4 Glossar y only uses one burst in 26. When the F ACCH steals control from the TCH small drop-outs in the speech can often be heard. Frame A repetiti ve collection of time slots in a TDMA system. GMSK Gaussian Filtered Minimum Shift Ke ying. The type of digital modulation used for the GSM system.
B-5 Glossar y RPE-L TP Regular Pulse Excitation Long T erm Prediction. A commonly used technique for con v erting voice from analog to digital form. This is the CODEC that is used by GSM, DCS1800 and PCS1900 systems. RSSI Receiv ed Signal Strength Indicator .
