Jitter figures of:
The Jitter SLA provides that Verizon’s Internet network (as defined in the Guide) monthly jitter performance will not exceed 1.0 millisecond on average. Performance is measured by periodically collecting data across the Internet network, from which a monthly average is derived.
Mean Opinion Score of:
Mean Opinion Score (MOS) is a measure (score) of the audio fidelity, or clarity, of a voice call. It is a statistical measurement that predicts how the average user would perceive the clarity of each call. The MOS SLA provides that the Verizon’s Internet Network (as defined in the Guide) MOS will not drop below 4.0 where MOS is calculated using the standards-based E-model (ITU-T G.107). Performance is measured by periodically collecting data across the Internet network, from which a monthly average is derived.
