On one device, only oneAuxiliary Flexible Interface Card with 4-Port 100Base-RJ45(FIC, Supporting
1588v2) can be housed.
Service access module
– Inputs 4-channel FE electrical signals.
– Implements physical-layer interface functions and supports Medium Access Control
(MAC) address-based communications.
– Supports the signal cache function to prevent FE signal loss.
– Supports the flow control function to control the packet volume.
– Processes IEEE 1588v2 packets.
Auxiliary interface module
– Provides 4-channel alarm input interfaces.
Control drive module
– Detects the system status through the management and control bus.
– Processes alarm signals, orderwire signals, and transparent data signals.
– Supports hot swapping.
Clock module
– Provides clock signals for service access and convergence module.
– Provides clock signals for the auxiliary interface module.
– Supports synchronous Ethernet and the Synchronization Status Message (SSM)
protocol.
– Supports IEEE 1588v2.
Power module
– Inputs 2-channel -48 V/-60 V DC power.
– Supplies 3.3 V or 1.2 V power.
