[mrtg] Question regarding Serial interface on 3725/DS3

I've got a 6MB DS3 on a Cisco 3725, and some of the values I've been
getting back
don't look right-

Here's what's at the bottom of the graph-

"Max  In: 100.1 kB/s (1.8%)   Average  In: 9202.0 B/s (0.2%)   Current
In: 42.4 kB/s (0.8%)  
Max  Out: 26.0 kB/s (0.5%)   Average  Out: 3040.0 B/s (0.1%)   Current
Out: 8115.0 B/s (0.1%)"  

I'm not sure why the average in is 9202K- is this 9.2 megs? (maybe I
just haven't had enough coffee yet)

The 5526.2 isn't right- but it's higher- the actual bandwidth available
top end
configured on the router is the ' dsu bandwidth 44210' that Bell South
had me put in-

They control the speed down to 6 MB on their end to meet our SLA.

Here's the relevant section of the config: built by cfgmaker
