Chapter 5 Configuring the Channelized Mode
Configuring a Channelized T3 Link
The following table explains the output of the preceding command, line by line:
Note
Unless unframed is selected, the BER test runs over the currently configured framing option for the
specified T1 line (SF or ESF). Before running a BER test, you should configure the framing option that
is appropriate to your application. (Refer to the
“Setting the Framing Format on a T1 Line” section on
page 5-15
.)
Terminating a BER Test
You can terminate a BER test with the
no t1
t1-line-number
bert
controller command, where:
t1-line-number
is 1 to 28.
Examples follow:
The following example terminates the BER test running on T1 line 10.
The example that follows is for a port adapter in slot 1 of a Cisco 7200 VXR router:
Router(config)#
controller T3 1/0
Router(config-controller)#
no t1 10 bert
To check your configurations using
show
commands, proceed to the
“Checking the Configuration”
section on page 5-25
; otherwise, proceed to the
“Performing a Basic Serial Interface Configuration”
section on page 5-24

Output Display Line
Explanation
BERT test result (running)
This line indicates the current state of the test. In this case,
“running” indicates that the BER test is still in process. After
a test is completed, “done” is displayed.
Test Pattern : 2^11, Status : Sync, Sync Detected : 1
This line indicates the test pattern you selected for the test
(2^11), the current synchronization state (sync), and the
number of times synchronization has been detected during
this test (1).
Interval : 5 minute(s), Time Remain : 5 minute(s)
This line indicates the time the test takes to run and the time
remaining for the test to run.
Interval : 5 minute(s), Time Remain : 2 minute(s)
(unable to complete)
For a BER test that you terminate, this line indicates the time
the test would have taken to run and the time remaining for
the test to run had you not terminated it; “unable to complete”
signifies that you interrupted the test.
Bit Errors(since BERT started): 6 bits,
Bits Received(since BERT started): 8113 Kbits
Bit Errors(since last sync): 6 bits
Bits Received(since last sync): 8113 Kbits
These four lines show the bit errors that have been detected
versus the total number of test bits that have been received
since the test started and since the last synchronization was
detected. Bits and errors are only counted when the test status
is “sync”.
