3 If you need to specify other settings for the test, press Cancel to return to
the Configuration menu.
The test mode is specified.
Configuring test settings
automatically
You can use the Auto Configure feature to configure the interface, framing, and
pattern settings automatically.
To configure the interface, framing, and pattern settings automatically
1 If you haven’t already done so, launch your test application (see
“Launching an E1 test application” on page 28).
2 Connect the E1Tester to the circuit.
3 On the test menu, select Action.
The Action menu appears.
4 On the Action menu, select Auto Configure.
The SmartClass E1 will attempt to automatically configure the interface,
framing, and pattern. If this attempt fails, the E1 tester will set the framing
to Unframed and the pattern to Live. You can also configure the framing
and pattern settings manually. See “Specifying E1 framing settings” on
page 31 and “Specifying a BERT pattern” on page 33.
The interface, framing, and pattern settings are automatically configured.
Proceed to configure the following settings for the test:
– VF settings, see “Specifying VF settings” on page 37.
– E1 signaling settings, see “Specifying E1 signaling (ABCD/Sa) settings” on
page 32.
– Defect and anomaly settings, see “Specifying Error/Alarm settings” on
page 35.
– Performance settings, see “Specifying performance settings” on page 36.
Specifying interface settings
Before you transmit E1 traffic, you can specify the characteristics of the inter-
face you want to transmit the traffic on, such as the line coding for the signal
you want to transmit, the transmit clock, and the slip reference for the receiver.
To specify interface settings
1 If you haven’t already done so, launch an E1 BERT application (see
“Launching an E1 test application” on page 28).
2 On the Configuration menu, select Interface Settings, and then specify
values for the following settings:
Setting Parameter
Line Coding Select one of the following line coding
options:
– HDB3: High Density Bipolar 3
– AMI: Alternate mark inversion
