Local authority: setting up the base station to grant CPEs
network access
If you establish local authority, the base station always grants CPEs network access. All CPEs
are placed on the same VLAN, which is the legacy VLAN.
To set up local authority:
1 Disable the AAA server feature:
set aaa state disabled
2 Configure the method the base station will use to grant network access to CPEs:
set aaa authority local
where local indicates the base station grants access to CPEs that want to connect to your
network.
3 To store the changes in Flash memory:
write
4 Reboot the base station. When the CPEs re-register with the base station, the base station
places them on the legacy VLAN.
Configuring the time signal used by base stations
Expedience base stations require a time synchronization signal in order to determine the
proper timing for time division duplexing (TDD).
Because most Expedience system deployments use multiple base stations, at multiple cell
sites, most service providers will configure their base stations to use the time synchronization
signal generated by the Expedience system’s global positioning system (GPS).
However, if your deployment includes only one base station or one cell site, you can disable
the use of an external GPS. Your base station will then use a time signal generated by a base
station for time synchronization.
The GPS supplied time signal is known as an external time signal, which is the default setting
of the base station when shipped from the factory.
The base station generated time signal is known as an internal time signal.
Configuring the GPS to supply the time signal
To use the GPS to supply the time signal to base stations:
1 Supply power to the entire system, as described in the section “Powering base stations” on
page 6-61 in this guide.
2 Connect the GPS to a base station, as described in the section “Connecting the GPS
equipment to a base station” on page 6-59 in this guide.
3 Connect all base stations in your cell to each other, in a daisy chain manner. For further
information, refer to the section “Connecting the GPS equipment to a base station” on
page 6-59 in this guide.
4 Configure the base station to use an external time synchronization signal:
set airlink timing external
