If you hear clicking during heavy data downloads, check that the DSLAM supports
quality of service (QoS) and that the ATM switch has the voice PVC provisioned for
vRT and the data at a lower priority. You may also be able to reduce or eliminate
clicking by adjusting the jitter buffer (see “Adjusting the Jitter Buffer” on page 10-4..)
The Port Monitor GUI program can show you the voice PVC and the last event
message. Use the Web GUI to verify the VPI/VCI or DLCI numbers for the data and
voice connections. Also check loop start (standard phone set) or ground start. These
values must match your Network Service Provider’s values.
