MOP for FDD SRAN SYNC from TDD LTE BTS (Airscale & FSMF)
GPS Synchronization from TDD LTE for FDD SRAN.
•
Support both Frequency and phase synchronization
•
GPS antenna with integrated receiver (FYGA) connected to MDR-26
Sync interface of the Flexi System Module
•
12V DC power for the receiver is supplied through the combined
power/data cable (FYHA up to 100 m, FYHB 30 m)
•
FYEA provides optional surge protection 20 KA 8/20 µs

Work Assumption
Airscale BTS ASIA/ FSMF for FDD SRAN
•
•
Sync Out and Sync In HDMI cable
for connection between TDD LTE SM on
FDD SRAN SM.
Cable Connectivity
HDMI cable to be connected in Sync Out of TDD ASIA/ FSMF to Sync
IN of FDD SRAN ASIA/ FSMF.
(AIRSCALE/FSMF)
MF) & SRAN (AIRSCALE /FSMF).
Sync setting in Both TDD SM (AIRSCALE/FS
1. Change the SYNC mode to Phase SYNC in TDD BTS.
2. Change the parameter as per the setting in image.
3. Modification can be done by SCF or manually, testing done with
manual setting.
4. Sync Input priority for GPS should be set to 1.
5. Sync input Type will be the 1PPS/TOD from Sync hub master …
6. Remove the parameter of older TOP Sync Configuration.
7. Set the value of total delay from SHM to 15.
8. Set the Synchronization master as Master.
9. Set the value of “maxbtstim
“maxbtstimeerror”
eerror” for FDD_LTE to default
value 1000 and for
GNBCF (2G) to 1900.
SYNC SETTING ON SRAN
Output :1. Sync would be phase, role as Slave and would be Synchronized
state.
