Protection Switching
1+1 Transmitter and Receiver Switching
Hot-Standby Transmitter Switching
Hot-standby (HS) Transmitter protection switching is automatically caused by
a Transmitter fault or by reverse path protection and is nonrevertive.
Reverse Path Protection
Reverse path protection software enables a HS radio to automatically switch
from the on-line Transmitter to the standby Transmitter when the Receiver has
a sync loss alarm. Reverse path protection is accomplished in less than 60
milliseconds.
HS Receiver Switching
Hot-standby Receiver protection switching is automatically caused by a
Receiver fault and does not revert to the main Receiver after the fault clears.
Path and maintenance switching do not introduce errors. Switching caused by
a fault introduces errors.
Space Diversity Receiver Switching
Space diversity protected Receiver switching is automatic and nonrevertive.
Space diversity receive switching is errorless and employs an anticipatory
function which uses performance degradation as an indicator.
Maintenance
Protected Transmitters and Receivers are arranged to allow repair of a single
Transmitter or a Receiver without removing the traffic.
