Figure 10 - PTP 400 Series Bridge Layer Diagram
The PTP 400 Series Bridge functionality has been extended to encompass the specification
IEEE 802.1p. IEEE 802.1p and uses Ethernet packets extended by 4 bytes, as specified in
IEEE 802.1q for VLAN tagging, to prioritize packets over the wireless interface. The PTP 400
Series Bridge will forward all VLAN tagged packets regardless of the VLAN ID value.
Each unit in the link is manageable through an IP connection. Standard IP protocols are
utilized for all management functions e.g. HTTP, SNMP, etc.
The PTP 400 Series Bridge is fully software upgradeable. New software images are first
downloaded from the Motorola website http://www.motorola.com/ptp to a convenient
computer. The image is then uploaded to the ODU via the web management page described
in Section 8.3.7 “Software Upgrade”. Once the image transfer has completed successfully the
image is written to memory. On completion of this process the unit can be rebooted to use the
newly uploaded image. Should this process fail the unit will revert to a protected image
installed during manufacturing to allow the unit to be recovered.
