Access Navigator - Release 1.8 August 2003 18-67
CLI Language Reference
CLI Command List
Example:
set ds1 9 line p2e15
The CLI will provide a progress message indicating the progress of the command, as
in the following example:
Message:
Sending pattern. Use 'send ds1 <n> off' to stop.
Send DS1 Line <pattern> Test
NOTE:
The DS1 must be set Out of Service, using the
set ds1 <n> down
command, before you can use loopbacks or test patterns.
NOTE:
Sending an unframed pattern will cause a DS1 Loss of Frame (LOF).
NOTE:
This command works with ESF and D4 (SF) framing.
NOTE:
The p2e patterns are intended only for Access Navigator loop tests
and for tests between two Access Navigators. Other test equipment will not
recognize these patterns.
NOTE:
Put the remote CSU or NIU in line loopback mode before using this
command for BER testing. (See Send DS1 CSU Loopup , Send DS1 Network
Loopup , and Send DS1 NIU Loopup .)
NOTE:
The internal Bit Error Rate Testers (BERTs) are always monitoring
the DS1 inputs. Anytime a BER test pattern is present, whether internally or
externally generated, the BER for the last one-second interval can be displayed
using the
status ds1
command (see Status DS1 on page 18-159 ). Bit errors
are also recorded in the BERT log (see Log BERT on page 18-40 ).
Purpose:
Transmits an unframed test pattern and performs a Bit Error Rate Test (BERT) to verify
the quality of the DS1 signal reaching far-end CSU equipment, such as the Access
Bank II.
When the operator enters the test command, the Access Navigator generates and
transmits the selected PRBS or QRSS test pattern while using its internal Bit Error Rate
Tester to measure the bit error rate (see Figure 18-6). Sending an unframed pattern will
cause a DS1 Loss of Frame (LOF) on both the Access Navigator and the remote CSU
for the duration of the test.
After 10 seconds the pattern is turned off and the test results from the BERT are
displayed in a CLI message. (The
send ds1 <n> off
command is not required to
turn off the pattern.)
qrss Send QRSS pattern (a modified 220–1) with a maximum of 14
consecutive zeros and 20 consecutive ones. (Common stress test
for T1 data applications.)
