11.1.1 Appearance and functions

Appearance
The iTN2100-TSU is a clock card used by the iTN2100. It can work with the iTN2100-
NTU-4GF to provide clock synchronization.
The iTN2100-TSU supports synchronous Ethernet and 1588 V2 time synchronization
protocol, and provides the external clock synchronization interface.
The synchronous Ethernet supports the following features:
