Signaling and Media Interfaces

The signaling and media interfaces provide network connectivity for signaling and media traffic. Each interface can connect to a network at 10-Gigabit speeds.

Network Interface Units (NIUs) are available in the following configurations:

• 2-port 10GbE NIU
• 4-port 10GbE NIU

The optical 10GbE cards can accept an LC fiber connector using either single mode or multimode cable.

Mixed transceiver types are not supported on SFP+-based NIUs because compliance testing shows that the NIU SFP+ ports must be populated with identical SFP+ types.

The Acme Packet 6350 supports the 4x10GbE NIU to provide greater session scaling and Packet Processing Module (PPM) support. The 4x10GbE NIU contains two Cavium 78xx chips running in parallel, and each one is attached to two 10GbE media interfaces. Each chip contains 64GB of DDR4 RAM. The increase in DDR4 RAM enables greater scaling capacity, and the use of DDR4 running at 1050MHz provides a memory performance boost.

Note:

When using the 4x10GbE NIU, you must put it in slot 0.
