TERMINATE MODE

Intrusive Tx to Customer and Rx from Customer

NOTE

This is an intrusive test and the original data path will be dis-
rupted.

The Tx of the BERT connects to the Tx of the test jack. The Rx of the BERT connects to the Rx 
of the test jack, 

Figure B-3

. The Tx data of the test jack is transmitted to the customer’s 

equipment while the Rx data from the customer is monitored. In this mode the monitor jack 
impedance of 432 ohms is removed from the data path. The BERT should be set to terminate 
mode.

Figure B-3.  Terminate Mode

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 T1 channel is selected, verify that the Test Jack Mode is set to “Intrusive”. 

If the Test Jack Mode is not set to “Intrusive”, change this parameter via the Loopbacks 
and Test\Test Port (Bantam Jack) Contro\Test Jack Mode screen. 

3. Verify the Intrusive Test Direction parameter is set to “Customer”. 

If the Intrusive Test Direction parameter is not set to “Customer”, change this parameter 
via the Loopbacks and Test\Test Port (Bantam Jack) Control\Toggle Intrusive Test 
Direction screen.
