GSM Testing
When provisioning or troubleshooting GSM networks, it is necessary to verify both voice quality and connectivity.
Non-intrusively monitoring traffic—including voice conversations and service statistics from a T1 access point verify
the A
bis
interface between the Base Tranceiver Station (BTS) and Base Station Controller (BSC)—provides a
comprehensive measure of network and circuit performance. This also allows for sectionalization of trouble between
different network elements. Finally, the 2207 can be configured to simultaneously display both service and physical
layer (T1) results and provide quick and easy differentiation between GSM service problems and T1 problems. The
2207 supports the following tests and measurements:
• Full rate and enhanced full rate traffic monitoring
• GSM traffic results including TRAU frame type values
• TRAU framing results
• Speaker/Microphone or handset functionality for checking voice integrity
• GSM LAP-D signaling results
• GSM Measurement Report message results such as average uplink signal quality and signal level
