5.3 Backup to Dual Kilostream Links
In a dual 64Kbit/s synchronous Kilostream link application, it is
necessary that when a failure of the link occurs, the failure is detected
and a backup is automatically initiated via the ISDN.
The unit then monitors the faulty Kilostream, to which data is
automatically restored once the link is functional and has been checked.
