Date and time must be set.

•

Actual pair loss for HDSL and HDSL2 should not exceed -35 dB at 196 kHz using a 135 # termination per link or

section. This is not a required test.

•

Actual pair loss for HDSL4 should not exceed -44 dB at 196 kHz using a 135 # termination for circuits not using a

regenerator or on the first link ( CO to regenerator) of a circuit using regeneration. Actual pair loss on the second

link ( regenerator to premise) should not exceed -41 dB at 196 kHz using a 135 # termination.

•

Sync light should be green for Adtran units. For ADC/Pairgain, reading should be between -64 to +64 for good

synchronization.
