1. The values are per port; for Acceleron 10G Aggregation, the performance numbers are for the 10G port aggregating the traffic of all twelve 1G ports on the Acceleron module
2. The CPS values are for the originating port, supposing the calls are terminated by the DUT. If Ixia ports are used to originate and termiante calls, then a pair of ports is needed to achive the specified level of CPS
3. The performances for Audio RTP are for the codec G.711 with ptime = 20ms
4. The perfomances for Audio and Video are for configurations with MOS enabled, Advanced stats disabled, and RTCP disabled
5. T.38 performances are for the following conditions: V17, Non ECM, 200 DPI, A4 Diago image; for V.34 the performances drop with 25%
6. N/A means the combination of Media and Signalig Protocols is not available
