4.2.3 Setting up Abis Signaling Link

After the configuration of the BTS3601C, MBPB will set up Abis signaling link
according to the configured parameters and exchange signaling with the BSC.
4.2.4 Setting up Cells
When Abis signaling link is set up, MB PB will report the configuration status of
BTS3601C resources to BSC and ask for logical configuration.
After BSC sends cell configuration data to MBPB, BTS3601C will configure the
relevant carrier attributes, set up common channel and update the overall messages.
So far the cell has been set up and MSs can access the network and originate calls.
4.2.5 Normal Operational Status
Once the BTS3601C comes into normal operation, MSs can access the network and
make calls.
However, sometimes it is found that although MTRM is in normal operation without
any critical alarms, MSs cannot access the network and make calls. To solve such
problem, the user can take the following measures:
Check whether MTRM has power output.
l
Check whether the system messages are issued normally.
l
Trace and locate the fault by using a signaling analyzer or the Abis interface
l
tracing function of the maintenance console.
During the operation, if the board ALM indicator flashes, it indicates that alarms have
been generated. In this case, the user can query at the BTS3601C terminal
maintenance console for specific alarm description and take the corresponding
measures.
4.2.6 Clock Reference Source
The cdma2000 1X is a synchronization system. A precise reference clock should be
provided for the BTS3601C.
The BTS3601C can receive the clock signal from multiple clock reference sources,
including: GPS clock reference source, GLONASS clock reference source and
external clock reference source.
