Brochure
The AR1200 complies with 3G standards including
CDMA2000 EV-DO, WCDMA, and TD-SCDMA, meeting
the wireless communication requirements between
branches and the headquarters. Users can use a 3G USB
disk to deploy 3G services on the AR1200, saving service
card slots. In addition, the 3G data link can be used as a
backup for wired link to protect the xDSL, FE/GE, and ISDN
uplinks. The backup link improves network stability and
reduces network construction costs. The AR1200 provides
the NQA function to detect 3G link quality, ensuring the
SLA.
