Monitoring IP link voice quality of service for IP Expansion cabinets
Behavioral characteristics of the network are dependent on the factors like
Round Trip Delay (RTD), queuing delay in the intermediate nodes, packet
loss and available bandwidth. The service level of each IP link will be
measured and maintained on the Main for IP Expansion operation.
Information for latency and packet loss will be collected from the hardware
and processed.
