The Packet Microwave Adapter card has two RJ-45 ports (ports 1 and 2) and six SFP ports (ports 3 through 8). All ports provide 10/100/1000 Mb/s connections (when connected to an MPR-e radio, they are always in Gigabit Ethernet (1-Gb/s) mode). Ports 1 through 4 support Microwave Awareness (MWA) and Ethernet/IP/MPLS networking; ports 5 through 8 support Ethernet/IP/MPLS networking only.
All Gigabit Ethernet ports provide the same networking feature capability as the 8-port Gigabit Ethernet Adapter card. For frequency synchronization, synchronous Ethernet and SSM are the mechanisms that are applied when using optical 1000Base-SX to connect to an MPR-e radio. When using electrical 1000Base-T to connect the Packet Microwave Adapter card and an MPR-e radio, Proprietary Clock Recovery (PCR) is used (a copper SFP is mandatory on ports 3 and 4).
