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.
