displayed list includes also the License ID (only BW license is applicable in the
current version) and the expiry date of the temporary grace period.
4.4.6 Chain
Future versions of BreezeMAX will enable chaining of co-located Base Stations to
fully support intra-site synchronization. When two or more Base Stations are
chained, all clocks and additional parameters required to ensure fully
synchronized operation of all sectors are sent from the Master Base Station to
other Base Stations. The Chain menu includes parameters that must be shared
by all Base Stations belonging to the same chain, where most of them should be
configured only in the Master Base Station (they will be read-only in other chained
Base Stations).
In the current release chaining is not supported yet and all Base Stations are
configured as Master Base Stations.
The Chain menu includes the following:
4.4.6.1 Chain Number
In future releases, when chaining will be fully supported, the Chain Number will
be used as a unique identifier of a chain. All Base Stations belonging to the same
chain should be configured with the same Chain Number. The Chain Number can
be used by a central management system to guarantee that certain limitations are
met: in each chain, one, and only one Base Station should be defined as Master.
Only one Base Station can be defined as Redundant (backup to the Master).
The range is from 1 to 1500.
The default is 0, indicating that a Chain Number is not configured yet. A valid
Chain Number must be configured, and this number must be unique in the
system to properly support future implementation of chaining.
4.4.6.2 GPS Supported
This is a read-only parameter indicating whether the use of GPS is supported by
the Base Station (through the Redundant CPLD in the NPU). The options are
Supported or Not Supported.
4.4.6.3 GPS Protocol
The GPS Protocol defines the communication protocol with the GPS receiver.
The available options are None, Trimble (for Outdoor GPS Receiver) and
Symmetricom (for Indoor GPS Receiver).
The default is Trimble.
