ToS Switch Detection, Voice Switch Detection

NOTE

Vipersat Configuration

Detection of the voice and video traffic occurs in the Remote modem classifier, which looks at traffic that is passed in both directions (Hub-to-Remote and Remote-to-Hub). Once the Voice and Video Switch Detection features are enabled, the Remote modem will send an Automatic Switch Request (ASR) to the VMS when an SIP and/or H.323 call is detected. The ASR contains the destination IP address of the RTP packets. If available hardware and bandwidth exist, the VMS will establish the SCPC carrier automatically.

Note: Application switching (voice and video) must be enabled for each CDM-570/570L in a network that is going to perform application switching in order for the VMS to dynamically optimize network circuit parameters to accommodate these applications.

Load switching by the VMS is not affected by this setting.

Voice Switch Detection

This menu item appears for Remote modems only.

Voice Switch Detection is one of the Application switching commands that provides for a dedicated SCPC connection when an SIP and/or H.323 voice call is made over the satellite network.

Entering O at the command prompt toggles the Voice Switch Detection command for the CDM-570/570L between Enabled and Disabled. When enabled, a voice data-stream will be detected, causing the CDM-570/570L to send a switch request to the VMS to switch from STDMA to SCPC mode.

Video Switch Detection

This menu item appears for Remote modems only.

Video Switch Detection is one of the Application switching commands that provides for a dedicated SCPC connection when an H.323 video call is made over the satellite network.

Entering I at the command prompt toggles the Video Switch Detection command for the CDM-570/570L between Enabled and Disabled. When enabled, a video data-stream will be detected, causing the CDM-570/570L to send a switch request to the VMS to switch from STDMA to SCPC mode.
