Synchronization Functions; Network Synchronized Mode - Ericsson MINI-LINK 6351 Technical Description

Synchronization Functions

By default, the packet radio works in Free Running mode. In this mode, the
packet radio is not a part of the synchronization network, and does not maintain
a SEC.
The packet radio can also be configured to work in Network Synchronized mode
where it maintains a SEC and distributes synchronization and synchronization
quality level status according to ITU-T G.8261, G.8262, and G.8264.

Network Synchronized Mode

Network Synchronized mode makes it possible to build a synchronized network
where all the NEs are synchronized to the same source. Figure 17 shows an
example of a network where the synchronization information is carried to all the
NEs through an assigned path. In case of link failures, the synchronization can
be reestablished using the unassigned synchronization paths.
Figure 17
In this mode, the packet radio uses the Node Clock on all the protocol layers
generated in the node.
