GENERAL
INFORMATION
Channel drop feature displays user-selected DS0
channel signaling bits, data bits, and VF frequency/
level measurements. In addition, the selected DS0
channel is dropped to the internal speaker and the VF
OUT jack for analysis by an external TIMS test set.
SUMMARY category displays either ALL RESULTS
OK or any out-of-specification or non-zero results,
eliminating the need to search through long lists of
test results.
AUTO mode lets the T-BERD 107A configure itself
to the proper framing, coding, and pattern. No setup
is required when monitoring live circuits.
Logic error and bipolar violation (BPV) insertion
enables the T-BERD 107A to simulate span and
equipment errors.
Line Build-Out selections add troubleshooting
capability to uncover marginal problems such as
cable crosstalk and bridge taps.
Rechargeable battery and AC power adapter
provide operating flexibility to meet different testing
needs. The lead-acid battery provides four hours of
continuous cord-free operation and can be recharged
from the T-BERD 107A AC power adapter.
VF OUT jack enables the T-BERD 107A to drop a
voice frequency signal from one channel to an exter-
nal test set for analysis.
RS-232 Interface connector enables the T-BERD
107A to print test results and test setup for various
tests.
