DAC GE Description
The DAC GE plug-in supports transport of Gigabit Ethernet LAN traffic. Three
10/100/1000Base-T ports and one SFP 1000Base-LX optical transceiver port are
connected to one or two 155 Mbps transport channels for transmission over a
9500 MXC link.
Features include:
• Extremely low latency, less than 360 microseconds for 2000 byte packets;
• Programmable switching fabric transparent mode, VLAN (secure) mode, or
mixed mode;
• Capacity increments of Nx1.5 Mbps, Nx2 Mbps, or Nx150 Mbps;
• Mapping of traffic to radio or fiber links;
• Ethernet traffic can be configured to ride side by side with PDH E1/DS1 traffic,
or the full capacity of a link can be dedicated to Ethernet.
• Comprehensive QoS policing and prioritization options (802.1p);
• VLAN tagging (VID and priority mapping).
• QinQ (802.1ad);
