in built csu on router

i hav erouter which is

Cisco 2811 (revision 53.51) with 249856K/12288K bytes of memory.

Processor board ID FTX1024A0Z1

2 FastEthernet interfaces

1 Serial interface

1 Channelized T1/PRI port

1 Virtual Private Network (VPN) Module

DRAM configuration is 64 bits wide with parity enabled.

239K bytes of non-volatile configuration memory.

250880K bytes of ATA CompactFlash (Read/Write)

it has in built csu.

when i do sh controller t1

it shows

sh controller t1

There are some aspects of your question that I do not understand well. What is the difference between csu/dsu stats and T1 stats?

The csu/dsu provides physical support for the T1 and controls functions such as clocking and framing for the data which is carried on the T1. In some sense perhaps the csu/dsu provide the lower level functions and perhaps you consider the T1 to be the packet level functions. In that case the statictics in the show command are csu/dsu stats.
