Reference Information 

The 8055T( GSM/DCS/PCS) is equipped 

with the latest encoding decoder and audio 

frequency technology, to achieve superior 

audio quality. 

At present, there are 3 types of encoding 

decoder compatible with GSM/DCS/PCS: 
yEnhance full rate  ( EFR)  
yFull rate  ( FR)  
yHalf rate  ( HR)  
 

The 8055T (GSM/DCS/PCS) mobile phone 

supports the normally -used EFR and FR 

encoding decoder. 

 

All GSM and DCS and PCS cellular 

networks and phones support FR encoding 

decoder. 

 

If supported by the network operator, the 

network operator will automatically select the 

relevant encoding decoder, which will be either 

EFR or FR.   

 

The 8055T model is programmed to 

automatically select the EFR where this is 

supported by the network, allowing you to 

enjoy the superior audio quality provided by 

EFR. Otherwise the phone will select FR. 

 

At present, only some networks support both 

the FR and EFR encoding decoder. 

If the network operator cannot support EFR, 

the 8055T  (GSM/DCS/PCS)  mobile phone 

will automatically adopt the FR encoding 

decoder.

(GSM/DCS/PCS) mobile phone include
