4.11.2 Configuration
The GPS Configuration menu enables managing the following:
4.11.2.1 Chain Parameters
Chaining of co-located BTSs is required to fully support intra-site
synchronization. When two or more BTSs are chained, all clocks are sent from the
Master BTS to the Slave BTSs. The Chain menu includes parameters that should
be shared by all BTSs belonging to the same chain.
The Chain menu includes the following:
4.11.2.1.1 Chain Number
The Chain Number is used as a unique identifier of a chain. All BTSs 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 BTS should be defined as
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
managed network to properly support chaining.
