All controls and indicators of the RTAU including the jack accesses for a selected DS1 signal 
are located on the front panel (Figure 3). The controls and indicators are described in Table 2. 

STATUS  

Red 

Module failure. 

 Yellow 

LED 

test. 

 

Green 

Module operating normally. 

B8ZS / AMI 

Green 

Indicates that the user has selected B8ZS line code for the bipolar 
interface. 

 

Yellow 

Indicates that the user has selected AMI line code for the bipolar 
interface. 

 

Off 

Indicates that the user has selected the internal signal monitor 
generator at the RTAU. 

Intrusive Test 

Yellow 

LED test. 

 

Green 

Indicates that the selected test mode of the RTAU is intrusive. 

 

Off 

No intrusive testing in progress. 

LINE CODE 

This is a pushbutton switch that toggles the DS1 interface between B8ZS, AMI, or 
the internal signal monitor generator at the RTAU. When B8ZS has been selected, 
the B8ZS/AMI LED will turn green; when AMI has been selected, the B8ZS/AMI 
LED will turn yellow; when the internal signal monitor generator at the RTAU is 
selected, the B8ZS/AMI LED will turn off. Using this switch overrides the Craft 
Interface RTAU Line Code field setting. 

DS1 RX 

Bantam jack connection from DS1 receive to test equipment. Bipolar DS1 signals 
from external test equipment can be applied to the RX jack for testing. 

DS1 TX 

Bantam jack connection from DS1 transmit to test equipment. Bipolar DS1 signals 
from external test equipment can be applied to the TX jack for testing. 

 

Note: The DS1 RX and DS1 TX jacks may be used with 22 AWG Plastic Insulated 
Cable (PIC) up to 655 feet in length. Access for drop or insert of DS1 signals 
towards the network (DS3 interface) or toward the customer (DS1 distribution 
modules) for monitoring and intrusive testing is configured through the Craft 
Interface or the TL1 interface.
