Figure 8: Detailed block diagram of design PROTECTED (SLAVE mode)
The user data ports LAN 1/2, SFP 2 are deactivated (don't transmit data from IDU). Port SFP 1 is
reserved for first IDU (Master – Slave) interconnection.
It is strictly recommended to use port LAN 3 as out-of-band management access port.
Function of Packet Processor is limited to receiving direction only, but its function is not important for
system function, because complete data stream is copied from protection bus (SFP 1) directly into
digital modem. Packet Processor just adds management channels into Fiber Optic high speed stream.
Protection is solved by means of Modem Card.
Main Advantages
1+1 protection in all modes HSB, SD, FD also with interface redundancy.
Disadvantages
Two units must be used for protection mode.
