Auxiliary Interface Function

Provide 2 external time/external clock interfaces to realize the input and output of external clock/external time information.

The external clock interface is a full-duplex interface, supporting 2Mbit/s and 2MHz modes; the external time interface is a half-duplex interface, supporting 1PPS+ time information and DCLS modes.

Provide 1 alarm output/alarm cascade common interface to realize 2-channel alarm signal output and 2-channel alarm signal cascade between subracks.

Provide 1 alarm input interface to realize 4-channel alarm signal input.

Provide one 10M/100M self-negotiating Ethernet network management interface.

Provide one 10M/100M self-negotiating Ethernet expansion interface for network management cascade.

Reserve 1 management/debugging serial port for OAM interface to PC or workstation.

Provide 1 cabinet alarm indicator output interface for outputting subrack alarm signals to cabinet indicators or other subrack cascade interfaces.

Provide 1 cabinet alarm indicator cascade interface for cascading alarm lights between subracks.

Clock Function

Synchronized Ethernet

Support

Synchronized Ethernet port SSM transmission and reception

Supports

IEEE 1588 V2 protocolb

Support

a: The service interface on the panel does not support the LAG function.

b: The 10GE service interface on the panel does not support the TC mode of the IEEE 1588 V2 clock.
