Redirection to 1xEV-DO 6.1.5.
This chapter describes an example of redirection where 1xEV-DO Band Class is 0 and Channel is 283.
1. Execute STDSEL CDMA2K to switch the system to CDMA2000.
2. Execute PRESET to perform CDMA2000 initialization.
3. Execute C2KSTD EV to set to 1xEV-DO.
4. Execute BANDCLASS 0,EV to set the Band class to 0.
5. Execute CHAN 283,EV to set Channel to 283.
6. Execute STDSEL LTE to change the system to LTE.
7. Execute PRESET to perform LTE initialization.
8. Execute IRAT REDIRECT_EVDO to set the destination at Redirection execution to 1xEV-DO.
9. Execute IRATC BC 0 to set the same values as the above CDMA2000 Band class settings.
10. Execute IRATC CH 283 to set the same values as the above CDMA2000 Channel settings.
11. Execute IRAT_STDCNG ON to set automatic switching when CS Fallback is executed to change Standard.
12. Perform LTE connection. (2.1.2, 2.1.3, 2.1.4)
13. Execute CSFB to set Redirection to 1xEV-DO.
14. Execute CALLSTAT? to query the call processing status is 2 (= Idle (Session Opened)).
(If not 2 (= Idle (Session Opened)), repeat step 14.)
NOTE:
To perform Redirection to 1xEV-DO at 1 Port, version 22.24 or later of the CDMA2000 software is
required.
