The 9500 MPR offers a SINGLE PACKET MATRIX that is able to switch, aggregate and
handle any of the possible incoming traffic types with virtually no capacity limits (up to 10
GBps).

Traffic with high priority, such as voice, will always have bandwidth available (deterministic
approach).
Broadband traffic is discriminated by QoS dynamically, with modulation scheme changes
driven by propagation conditions.
