T1 is not half-duplex! You get 1.536Mbps in each direction simultaneously on
a full T1. It is common to use Fractional T-1, where a subset of the 24
DS0s are used. (I designed T1 and FR equipment in an earlier life).

If you look at the sh int output, he has more than one QoS VLAN setup...one
for office1 (128kbps) and one for office2 (650 kbps). That's 778 kbps (I
think it should be 768 kbps, but whatever. Factoring in full duplex
communication over the T1, it's 1.5 MBps, which is what he should be
seeing...unless I'm doing the math wrong...

If he thinks he has a T1 and the CIR is 128, they had better up it then.
Otherwise you might want to check the bill. That COULD be a frac T. ;-)

Keep in mind that while you may have a physical T1, the interfaces are set
up for Frame Relay. Chances are those settings are matching the Frame Relay
"Committed Information Rate" (CIR), which is the rate at which you may send
traffic at a steady rate and expect that it will not be dropped (when you
burst over that rate it is "best effort" delivery).

The bandwidth statement on the router is purely for routing metrics on
certain protocols. Depending on your configuration, it could be painful...

Sort of off the topic but I've been frustrated with speed issues over our
LAN. I don't know much about Cisco routers but here is a snippet of "sh
int" from my Cisco 2600.
It is a T1 out and all our offices have T1 in. my question is: The "BW"
(bandwidth) entry is different on all the serial interfaces, our vendor said
it doesn't matter what is written but that the BW # is only for calculations
with the reliability or some crap like that. Anyone know the truth?
