Notes:
1. The
lp-up
(loop-up) and
lp-dn
(loop down) codes are not supported for CEPT or HDSL
WANs. Turning any of these tests on or off will cause a temporary interruption of data
transmission on the DS0 time slots as well as on the FDL bit of the corresponding port.
BERT
The Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected WAN port. The patterns that can be selected are
off
,
mark
(all ones),
space
(all zeros),
1:1
(0101),
1:7
(0100 0000),
3:24
(this pattern requires 3 bytes to display),
qrss
(quasi-random signal source),
lp-up
(which sends a T1 loop-up code to the remote end) and
lp-dn
(which sends a loop-down code to the remote end). The last two options are not
available for WAN cards with CEPT or HDSL modules.
Action Function
Save Saves changes to settings.
Undo Returns all settings to the last saved state.
Refresh Updates certain time-related information fields that are not automatically
updated (i.e., performance and test data).
Insert Err Allows you to manually insert a single bit error into the data signal. This does
not cause a CRC error.
Clear Clears the Test Screen and resets all counters to zero.
Main Returns to the WAN Card Main Screen. If changes are made to settings and
not saved, you will be prompted to save or abandon those changes.
