Monitor Tx to Customer
The Rx of the monitor BERT receives data from the TX point of the test jack, Figure B-1. This
monitors the data that the customer’s equipment is receiving from the network equipment.
Figure B-1. DSX MON, Tx to Customer
To set up the QDFR for this mode the following sequence must be performed:
1. Select the correct T1 channel to monitor.
This is accomplished by accessing the front panel switch or from the craft port interface.
2. After the correct T1 channel 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.
