What is the difference between High and Low Class of Service (CoS)?
A Low CoS is when the bandwidth is not guaranteed. Your bandwidth will be dependent on how else your network is being used.
A High CoS means you will have 100Mpbs at the Network Termination Device (NTD) available at all times, no matter how else the network is being used.
High CoS costs more as you get the dedicated speed guarantee and is ideal for businesses that use data reliant applications, including voice, video conferencing and CRM database queries.
