26
Multiframe output data generation
Coding scheme Full-rate speech [TCH/FS]
CS-1, CS-4
Data PN9 or PN15
The selected data sequence is coded continuously
across the RLC data block as per ETSI TS 100 909, 3GPP
TS 05.03, V8.9.0, 2000-11 [release 1999]
An independent version of the selected data sequence
is coded across the MAC header.
Frame structure 26-frame multi-frame structure as per ETSI
GSM, 05.01 version 6.1.1 [1998-07].
[Coding is done on frames 0-11, 13-24, of the multi-frame.
Frame 25 is idle [RF blanked].]
Adjacent timeslots
Data PN9, PN15 coded as per ETSI TS 100 909, 3GPP
TS 05.03, V8.9.0, 2000-11 [release 1999].
Frame structure 26-frame multi-frame structure as per ETSI GSM,
5.01 version 6.1.1 [1998-07].
Multiframe measurements 1
GSM measurement modes
Static sensitivity RBER at user-specified power level measured.
[This is the complete conformance test as defined in
pri-ETS 300 609-1 [GSM 11.21] version 4.12.0 [Dec 98],
section 7.3.4.]
Sensitivity search Automatically finds the input level [sensitivity] that causes
a user-specified RBER [normally 2%] for class II bits.
Maximum frame count 6,000,000 speech frames
GSM measurement results Class Ib bit-error ratio [RBER for TCH/FS]
Class II bit-error ratio [RBER for TCH/FS]
Frame erasure ratio [FER]
Downlink error frame count
Class Ib bit-error count
Class II bit-error count
Erased frame count
Total frame count
Maximum RBER 50%
Maximum FER 100%
Alternate time slot power level control
[Valid for standard attenuator only. Not applicable to Option UNB or Option 506]
Amplitude is settled within 0.5 dB in 20 µsecs, +4 to –136 dBm at 23 ±5 °C
1. Measurements also require Option 300.
