– This mode is used for replacement of NPU
– Default user names and passwords are used for the NE
– It is entered by inserting the NPU in an active NE and immediately
pressing the BR button during NPU power up (Fault (red), Power
(green) and BR (yellow) LEDs on the NPU are ON).
– The BR (yellow) LED starts flashing after about two minutes.

|-- tn_backup_configuration
|-- tn_error_log
|-- tn_licenses
|-- tn_system_release
|-- ml_tn_software

Configuration page.

145. Terminal Parameters
• Terminal ID — The name or id number of the Radio Terminal
• Far End ID — Specifies the expected identity of the Radio Terminal on the
other end of the radio link. If Radio ID Check is enabled, this identity must
match the identity of the far-end terminal.
• Radio ID Check — Controls that the received traffic originates from the
correct far-end Radio Terminal; if not, an alarm is generated.
• Mode — Specifies the protection mode of the Radio Terminal.
Note: Protection modes other than 1+0 require a license.
– Not Defined — Indicates a mismatch in a protected Radio Terminal. For
example, it has been configured as 1+1 Hot and then one MMU2 H is
removed.
– 1+0 — Specifies an unprotected Radio Terminal.
– 1+1 Hot — Specifies a protected Radio Terminal in hot standby mode. Only
available if there are two units in the correct positions.
– 1+1 Work — Specifies a protected Radio Terminal in working standby mode.
Only available if there are two units in the correct positions.
