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.
SYNC
The Synchronization (SYNC) field tells you if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test equipment.
Since this is an information-only field, there are no user-selectable parameters.
BE
The Bit Error (BE) field shows the total number of bit errors logged. Since this is an
information-only field, there are no user-selectable parameters.
ES
The Errored Seconds (ES) field shows the total number of seconds in which any errors were
detected. Since this is an information-only field, there are no user-selectable parameters.
