Table 9 - 4.9 GHz variant – Aggregate Ethernet Throughput Rates
9 Data rates for the Lite version of the PTP 400 Series Bridge variants are 50% of the figures shown.
10 These data rates are reduced when AES Encryption or ARQ (Automatic Retransmission reQuest)
are enabled.
11 4.9 GHz Variants do not have a Low Latency Mode
12 AMOD link margin of 1.5dB applied
