66 ALFOplus 24GHz (North America) - Release 01.05.0x - MN.00395.E - 004
The other configuration present in SIAE equipment that manage the role of the LAN interfaces (Master/
Slave) is present in the main configuration of each LAN interface. Regardless if each LAN interface is set
manually as Master/Slave or with autonegotiation, the setting of dynamic or static in the SSM configuration
is privileged. In other words if the Master/Slave are set manually in the interface configuration and in the
SSM is set “According to synch direction”, if needed, the role of the LAN changes according to synch direc-
tions.
When an electrical GE interface is in Master State (despite from the fact that it comes from a “static” or
“dynamic” setting) every synchronization signal that is coming from this interface has automatically the
quality of DNU. This does not occur for optical GE or FE interfaces (Electrical and Optical), where the “Mas-
ter” and “Slave” roles are not foreseen and so the transmitting direction for the clock can be exchanged
without any port role re-negotiation.
All the Ethernet interfaces are locked on the SETS, regardless which LAN interfaces are set as sources of
synchronization. Nevertheless the “Overwrite RX Quality” and “Overwrite TX Quality” can be applied only
on the LAN interfaces used as sources of synchronization.
