Description
One of the four possible service flow queues that exist in the router.
Service Identifier, a 14-bit integer assigned by the CMTS to each active
upstream service flow.
The type of SID:
•
Primary—The service flow used for best-effort data traffic and MAC
maintenance messages.
•
Secondary—Secondary static service flows that are created at
power-on provisioning for voice calls when dynamic SIDs are not
active.
•
Dynamic—Secondary service flows that are created for on-demand
voice calls when using dynamic SIDs.
Service Flow Identifier, a 32-bit integer assigned by the CMTS to each
service flow on the router.
