Data network planning
This section describes factors to be considered when planning PTP 650 data networks.
Ethernet interfaces
The PTP 650 Ethernet ports conform to the specifications listed in
Table 32 PTP 650 Ethernet bridging specifications

Interfaces
Max Ethernet frame size
Service classes for traffic
Practical Ethernet rates depend on network configuration and higher layer protocols. Over the air
throughput is capped to the rate of the Ethernet interface at the receiving end of the link.
Layer 2 control protocols
PTP 650 identifies L2 control protocols from the Ethernet destination address of bridged frames:
Table 33 Destination address in layer 2 control protocols
Destination address
01-80-c2-00-00-00 to 01-80-c2-00-00-0f
01-80-c2-00-00-20 to 01-80-c2-00-00-2f
01-80-c2-00-00-30 to 01-80-c2-00-00-3f
