In a DSLAM-to-standalone configuration:
The devices synchronize without altering factory defaults, since the CO unit
defaults to LTU mode, and the CP unit defaults to NTU mode.
In a standalone-to-standalone configuration:
One unit must be changed to run in LTU mode, since standalone units have
a factory default setting of NTU mode.
In both cases the clocking source may have to be altered depending on network
requirements.
Choosing a Configuration Mode
You can make configuration changes either through a VT100-compatible terminal
and the unit’s Configuration menus or by manually changing switches on the
board. The unit comes configured to allow settings to be made through the
Configuration menus.
Configuring the Unit Using the Configuration Menus
Use the Configuration menu to select, display, or change configuration option
settings.
NOTE:
The 7984 Standalone Termination Unit is preconfigured as an NTU. If you
are using this unit as an NTU, the configuration options may not need to be
altered.
The 7984 Standalone Termination Unit has two sets of configuration option
settings:
The Current Configuration (the 7984 Standalone Termination Unit’s active set
of configuration options)
The Default Factory Configuration (A read-only configuration area containing
the factory default configuration options)
To display configuration options, you must first load a configuration into the edit
area. To load a configuration option set into the configuration edit area, follow this
menu selection sequence:
