Tx Switch Criteria
Switching from the online Tx to standby is initiated for the following
local
alarm
conditions:
• Software load failure
• Tx path failure:
• Tx synthesizer not locked
• Transceiver Tx failure
• Tx power failure
• Tx IF synthesizer not locked
• Tx cable IF synthesizer not locked
• ODU Tx cable IF synthesizer not locked
• ODU cable unplugged
• Tributary LIU failure. Except for IDU 20x when configured for capacities
above 20xE1 / 16xDS1 using ‘Hot Standby: Non-protected Tributary’.
• Tributary ‘n’ LOS failure (subject to no trib ‘n’ LOS on partner IDU trib).
Except for IDU 20x when configured for capacities above 20xE1 / 16xDS1 with
‘Hot Standby: Non-protected Tributary’.
A transmitter switch is also forced for an undetected ‘silent transmitter’ failure.
This occurs when both
remote
online IDUs are in
receive
alarm (path failure),
whereupon a switching command is returned to the local-end transmitter

.
Rx Switch Criteria: IDU 20x and IDU 155o
This data is applicable to hot-standby and space diversity.
Switching from the online Rx to standby Rx is initiated for the following alarm
conditions:
• Software load failure
• Tributary LIU failure. Except for IDU 20x when configured for capacities
above 20xE1 / 16xDS1 using ‘Hot Standby: Non-protected Tributary’.
• Tributary output failure. Applies to IDU 20x, except when configured for
capacities above 20xE1 / 16xDS1 using ‘Hot Standby: Non-protected
Tributary’. This alarm condition does not apply to IDU 155o.

Where both RF modules are in receive path alarm because of a path problem, no signal is received in
either direction. In such situations the ‘silent Tx’ switch command will be prompted by receive path
alarms at both ends of the link, but will not be received at the transmit ends of the link, hence no silent Tx
switch will occur on a complete (both-way) path failure.
