HSB Radio Protection Overview
IP-20C and IP-20S support 1+1 HSB radio protection. IP-20C also supports
2+2 HSB radio protection. In HSB radio protection, one IP-20 operates in
active mode and the other operates in standby mode. If a protection
switchover occurs, the Active unit goes into standby mode and the Standby
unit goes into active mode.
For a full explanation of 1+1 HSB radio protection and 2+2 HSB radio
protection support in IP-20C, refer to the IP-20C Technical Description.
For a full explanation of 1+1 HSB radio protection support in IP-20S, refer
to the IP-20S Technical Description.

Configuring HSB Radio Protection
You must perform the initial configuration of a 1+1 or 2+2 HSB system using a
splitter cable for each unit to provide a management connection to each unit.

Ethernet traffic must be routed to each unit via an optical splitter cable.
