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

T1 0/0/0 is up.

Applique type is Channelized T1

Cablelength is long gain36 0db

No alarms detected.

alarm-trigger is not set

Soaking time: 3, Clearance time: 10

AIS State:Clear LOS State:Clear LOF State:Clear

Version info Firmware: 20060711, FPGA: 13, spm_count = 0

Framing is ESF, Line Code is B8ZS, Clock Source is Line.

CRC Threshold is 320. Reported from firmware is 320.

Data in current interval (749 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

66 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

66 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

Total Data (last 24 hours)

0 Line Code Violations, 11 Path Code Violations,

7394 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 11 Degraded Mins,

7404 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

what are these stats doe it show csu /dsu stats or T1 stats

thanks

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.

Hi rick,

thanks for reply

so sh controller T1 always show stats of inbuilt csu/dsu?
