You can use the offset values to adjust the CPE transmit reference PSD relative to the default reference
of –140 dBm/Hz. Only reference PSD values greater than –140 dBm/Hz are supported. A zero value for
the offset corresponds to a reference PSD of –140 dBm/Hz.
The smallest offset is 30 dBm/Hz and the corresponding value is 300.
Caution Changing the noise model while the switch is functioning in a network can disrupt the network
operation.
When you enter the lre upbo command, all LRE links are reset to the up state.
Before configuring the reference TX power level, follow these guidelines:

Examples This example shows how to set the noise model to ETSI-A:
Switch# configure terminal
Switch(config)# lre upbo etsi-a
This example shows how to set the offset value to 450 (45.0 dB):
Switch# configure terminal
Switch(config)# lre upbo offset 450

Make sure all the CPEs in the production network are running the same LRE binary version. Use the
show controllers lre cpe version privileged EXEC command to display the binary version on the
all CPE device interfaces.
