Figure 12 – PTP 600 Series Bridge Layer Diagram
The PTP 600 Series Bridge functionality has been extended to encompass the specification
IEEE 802.1p. IEEE 802.1p 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 600
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. HP, SNMP, etc. The unit can be configured to use
VLAN tags on the management interfaces.
The PTP 600 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 8.3.6 "Software Upgrade". The compressed image is first loaded into RAM and
check-summed. If the compressed image transfer has completed successfully the image is
decompressed and written to Flash 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 compressed image installed during manufacturing to allow the unit to be recovered.
