Transparent Ethernet service
The PTP 700 Series provides an Ethernet service between one of the Ethernet ports at a local
ODU and one of the Ethernet ports at an associated remote ODU. The Ethernet service is based
on conventional layer two transparent bridging, and is equivalent to the Ethernet Private Line
(EPL) service defined by the Metro Ethernet Forum (MEF).
The service is transparent to untagged frames, standard VLAN frames, priority-tagged frames,
provider bridged frames, Q-in-Q frames and provider backbone bridged frames. In each case,
the service preserves MAC addresses, VLAN ID, Ethernet priority and Ethernet payload in the
forwarded frame. The maximum frame size for bridged frames in the customer network is
9600 bytes.
There is no requirement for the customer data network to be connected to the same Ethernet
port at both ends of a wireless link. For example, it is possible to connect the Main PSU port to
the customer data network at one end of the link and to connect the Aux port to the customer
data network at the other end of the link.
Layer two control protocols
The Data Service in the PTP 700 Series is transparent to layer two control protocols (L2CP)
including:
Spanning tree protocol (STP), rapid spanning tree protocol (RSTP)
