Calculate Bandwidth Utilization for E1 Using SNMP

Hi.

I need to calculate Bandwidth utilization for E1interface via SNMP.

I tried to use information from this article http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a008009496e.shtml

Last night I've got the following data from my Cisco 3845:

TimestampifDescrifTypeifSpeedifInOctetsifOutOctetsDifInOctetsDifOutOctetsInBandwidthOutBandwidth
11/16/10 09:17:54Serial0/1/0:0propPointToPointSerial20000008432638871375140745160094353556414
11/16/10 09:18:54Serial0/1/0:0propPointToPointSerial200000085948300413776233712703184137710817
11/16/10 09:19:54Serial0/1/0:0propPointToPointSerial20000008732542581380108133229520414129217

DifInOctets = delta(ifInOctets)/delta(time)

As you can see I've got InBandwidth>100%

Why it so?

If I change ifSpeed from 2000000 to 2048*1024 bits per second (right value for E1 interface) it doesn't give me  InBandwidth<100%

In attachment you can find a part of gateway config
