Video Provisioning Constructs
The Video Services Provisioning Model has the following elements:
-
Logical Edge Device (LED)—a virtual edge device in the Cisco cBR-8 chassis that can be provisioned for static or dynamic sessions.
-
Virtual Carrier Group (VCG)—a collection of Virtual QAM Carriers (RF channels) provisioned on an LED.
-
Virtual Edge Input (VEI)—assigned either globally to all VCGs in the LED or optionally assigned uniquely to an individual VCG.
-
Service Distribution Group (SDG)—a collection of one or more RF ports that define the physical slot/bay/port to be used in a video service.
Connection of Virtual and Physical Constructs
The VCGs are bound to an SDG using a bind command (bind-vcg). This connects the virtual carriers to the physical ports listed in the SDG. After binding, a path from the VEI is mapped to the RF ports.
