ESTING WITH
The H2TU-R BERT Generator screen allows transmission of a test signal from the H2TU-R towards either the
network (NET) or customer (CPE). Bit error rates are calculated and display on the Monitor screen.

The test pattern is sent out either from the line unit towards the network (toward NET) or from
the remote unit towards the customer (toward CPE). Both test payloads must be looped back so
they can be returned to the unit for BER detection. BER detection is performed in the line unit
for both switch settings.
Tests done towards the NET must be looped at some point external to the higher circuit. Tests
done towards the CPE can either be looped back at some external point beyond the remote unit,
or they can be looped back internally by a higher loopback, such as NREM. The test payload,
for the CPE direction, also passes back and forth over the HDSL2 link to the H2TU-C before it is
analyzed for errors.
