Initial Connection
Class selector (CS): this mechanism allows for a selection of seven options which
prioritizes the data packets as per the option bits within the Type of Service (ToS) byte.
The combination of all three IP Precedence bits is used to adjust the IP packet
prioritization within the network.
Expedited forwarding: this mechanism is used when the data traffic is targeted to have
low delay, low jitter, low loss and low latency, hence prioritizing bandwidth to target a
“point-to-point” communication experience.
The recommended differentiated services setup are: AF41 (Assured Forwarding 41) or EF
(Expedited Forwarding). The AF41 shall be used whenever video related data is part of the
wireless solution and EF shall be used for any other solution which doesn't include video as part
of the package.

2. Select Save Backup.
3. The Gateway collects the configuration date and when the file download pop up
appears, select Save.
4. Enter a save location and file name.
5. Select Save.
6. Select Return to form.
Note
System backup contains user passwords and keys used for encrypting communication. Store
downloaded system backups in a secure location.
