E1 and Timeslot Network Testing
Configure the DS3 and Higher-rate Signals
Configure the DS3 and Higher-rate Signals
If you are testing E1 signals mapped to and from a DS3 signal, you need
to set the DS3 signal parameters after you have configured the E1
parameters. You also must configure any higher-rate signals on which
the DS3s are carried.

1. Use FIELD and VALUE to configure the DS3 transmit and receive
levels (Rx and Tx). These fields are not displayed when the DS3 is
carried on a higher-rate signal.
E1/TS
For information on DS3 setup,
see DS3 Setup Parameters,
page 7–2.
2. Next set the DS3 timing source (TxClk), framing format (Frm),
transmit X-bit status (XBit), and transmit FEBE bits (FEBE).
3. Configure the SONET parameters as appropriate for your
application. Set the transmit timing source (TxClk), scrambling,
and transmit and receive levels (Tx and Rx).

If you are testing timeslot traffic on the E1 signal, you can configure
the TS parameters now. See Configure the Timeslot Parameters,
page 14–7.
•
If you are not testing the TS signals, you can begin the test right
now. See Run the E1 Test, page 14–10.
