RE: Serial Inteface w/ builtin CSU/DSU question

[Taylor, Don]

It will run a self-test every time you reboot the router and you can view the results with a "show service-module" command. Here's the output from mine (the salient line is surrounded by asterisks that I added):   Bravo#sho service-module Module type is T1/fractional     Hardware revision is 0.80, Software revision is 1.07,     Image checksum is 0x8510A6B6, Protocol revision is 0.1 Receiver has no alarms. Framing is ESF, Line Code is B8ZS, Current clock source is line, Fraction has 24 timeslots (64 Kbits/sec each), Net bandwidth is 1536 Kbits/s *****Last module self-test (done at startup): Passed***** Last clearing of alarm counters 5d16h     loss of signal        :    0,     loss of frame         :    0,     AIS alarm             :    0,     Remote alarm          :    1, last occurred 5d16h     Module access errors  :    0, Total Data (last 96 15 minute intervals):     0 Line Code Violations, 0 Path Code Violations     0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins     0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs Data in current interval (262 seconds elapsed):     0 Line Code Violations, 0 Path Code Violations     0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins     0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs -----Original Message----- From: Raul Fernandez [mailto:[EMAIL PROTECTED]] Sent: Saturday, November 25, 2000 3:28 PM To: 'Cisco group study' Subject: Serial Inteface w/ builtin CSU/DSU question Dear Group,   Are there any built in test in CISCO routers with built in CSU/DSU that will let you test the CSU/DSU? I know about loop back test ect and debuging the serial interface itself but I am looking for commands that test the internal CSU/DUS specifically. Thank you for time.   Sincerely,   Raul
