If your CIR is 1536 then your CBR doesn't really matter because the T-1 line
will be saturated (full) when you hit your CIR. The graph you posted shows
you are using around 12% of your total capacity.
12% of a t-1 internet connection can mean only one thing. Nobody's
installed napster yet. :> Realistically though, your usage is fine, you've
got plenty of room to grow. If you are having speed problems, it's not
because of Bandwidth.

We are getting a CIR of 1536. The CBR changes all the time... we only
operate during the day since we're a school and the only statistics that I
get from our ISP is a 24/hr report which does me no good.

It means that you are only using 180kbps of your 1540kbps T-1 service. From
the information given though, we don't really know how much bandwith you
_actually_ have though because you are using Frame-Relay. To determine the
real amount of bandwith you have, you'd need to know the CIR and CBR of your
Frame-relay circuit.
(Explanation: The T-1 just connects you to a frame-relay switch in a
service providers office. If the service provider sells you a 56k CIR
circuit, then you are going to get around 56k of data through it, regardless
of how big the connection to the service provider is.)

What's up everybody.... I have just installed MRTG and am monitoring our T1.
My question is this:
The max Bytes Per Second only goes up to 180k. How does this correlate to
actual bandwidth being used up on my pipe? I have a 2600 with a built in
CSU/DSU (bandwidth set to 1536kbps).... over frame relay.
(see .gif for example)
I've been looking on CCO for the max kbps that it can actually route, but no
luck. I'm assuming that it can handle the 1536?
Cheers,
Jeff
