Here is the breakdown you have a Partial T coming into a router SE0, it is
Frame you are only using 12 channels --> Port Speed 768, You have two PVC's
riding this partial T SE0.1 and SE0.2 both are 384 K through the frame
cloud, But because your traffic is bursty and you are trying to save your
company a buck or two you only have a CIR of 192K I.e. the Telco guarantees
192K get's through. This makes a lot more since when you are talking
connections with oversubsciption i.e. a T1 1.544 port speed and 24 128K PVC
speed circuits, with CIR of 64, You are not truly over subscribing here if
you are the Telco because you can still get 64 K to all customers. Sorry if
I babbled need more caffeine....
