Monitor Rx from Customer

The Rx of the monitor BERT receives data from the RX point of the test jack,
monitors the data that the customer's equipment is transmitting to the network equipment.
To set up the QDFR for this mode, the following sequence must be performed:
1. Select the correct T1 channel to monitor.
This selection is accomplished by accessing the front panel switch or from the craft port
interface.
2. After the correct port Is Selected, Verify That The Test Jack Mode is set to "Monitor".
If the Test Jack Mode is not set to "Monitor", change this parameter via the Loopbacks and
Test\Test Port (Bantam Jack) Control\Test Jack Mode screen.
The Intrusive Test Direction parameter is not applicable for this mode. In this mode the
data has a monitor jack impedance of 432 ohms. The BERT should be set to a monitor
mode. The BERT Tx is not used. This test is non-intrusive.
