Installation of Flexi BTS Synchronization with GPS （Optional）

Installation of Flexi BTS Synchronization with GPS （Optional）

• 472748A FYGB GNSS Antenna Kit

• 471605A FYMA GPS Mounting Kit

• 471606A FYHA GPS Cable Set 30m for FSME, or

• 471653A FYHB GPS Cable Set 100m for FSME

• 472510A FTSE GPS cable assembly 30m for FSMF, or

• 472577A FTSH GPS cable assembly 100m for FSMF

• 471822A FYEA GPS Surge Protector Kit (optional)

• GPS used as the source for frequency and time synchronization

• Note other synchronization options :

- 2M/10M clock from existing BTS

- PDH (e.g. via E1/T1, e.g. from co-located existing BTS)

- Synchronous Ethernet

- IEEE1588v2, Timing over Packet (ToP over Ethernet)

• Note System Module contains an oven controlled oscillator (OCXO), which provides a highly stable clock even if the GPS receiver fails or GPS signal is temporarily unavailable

• The GPS antenna with integrated receiver (FYGA) has to be installed outside for satellite visibility and is directly connected to the MDR-26 Sync interface of the System Module

• 12 V 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 (GR 1089 or IEEE Std C62.41.2-2002)
