3. Use VALUE to select from which DS3 signal the test set drops and
inserts DS1 channels (DS1 From DS3).
4. Press FIELD and then use VALUE to set the operation of the
front-panel DS3 LED indicators.
5. Next use FIELD and VALUE to set the signal parameters for DS3-B
as you did for DS3-A (see Configure the DS3 Signal, page 6–4).
Note: For test sets with receiver-only dual DS3, the DS3-B parameters apply only to
the receiver. The DS3-B transmit signal is a passthrough of the receive signal.

After you finish configuring both DS3 signals, you are ready to begin
the test. See Run the DS3 Test, page 6–10.
