Additional port allocation rules
The three Ethernet ports are generally interchangeable, except for some specific additional
rules listed below:
•
If the TDM interface (E1 or T1) is enabled, ensure that only the Main PSU port is allocated
to Data Service
•
If the system is to be used in a Synchronous Ethernet hierarchy, ensure that the upstream
timing source is connected to the Main PSU or Fiber SFP ports (downstream devices can be
connected to any port)
•
If the system is operating as an IEEE 1588-2008 Transparent Clock, ensure the data path
traverses only the Main PSU or Fiber SFP ports at both ends of the link.
Note
The Main PSU port is always used to supply power to the ODU, even when it is not
allocated to a data or management service.
Note
The procedure for configuring these ports at the web interface is described in
Note
Transparent Clock is not supported over the Aux Port and SFP port with Copper
connectivity.
