ALPOS48 Product Brief
ALPOS48 Overview
ALPOS48 flexible interfacing processor point-to-point ring configured POS/EOS other packet encapsulation over OC48, OC12 optical links. ALPOS48 trunks GMII gigabit ports OC48 packet link, with IP/MPLS protocol mapping packet directing, tagged/untagged header insertion removal. Operations packets protocol/packet type programmable dynamically in-band reconfigurable. typical POS/EOS application with RoX-IIswitch IC's follows:
EtherNet switch/router
