DESCRIPTION  
LED INDICATOR FUNCTIONALITY  
The AC powered ADTRAN 6540 SHDSL 2-Wire/4-Wire NTU (P/N 1230001L1) functions as an  
interface between the SHDSL network and the Data Terminal Equipment (DTE) for applications such  
as LAN-to-LAN bridging, Frame Relay circuit, and PABX termination. The 6540 is designed to be  
used either as a remote unit to the ADTRAN Total Access® 3000 multiservice platform, or as a pair of  
units in a point-to-point limited distance campus configuration, with one 6540 configured to “LT”  
mode.

LOCAL LOOP/  
ERR INJ  
If a port is selected, and a Bit Error Rate Test (BERT) is not in progress, press the LOCAL  
LOOP/ERR INJ button to initiate or terminate a local loop on the selected port. If a BERT is  
in progress, press the button to inject a single bit error.  
Yellow Active BERT and one or more test pattern bit errors have been received  
Red Active BERT but the test pattern detector is not synchronized  
REMOTE LOOP  
1. Minor SHDSL port alarms: CRC errors, Loop Attenuation Threshold Alarm, SNR Margin Threshold Alarm, Segment  
Anomaly, and any ES, SES, UAS, CVC, and LOSWS 15-Minute Threshold Alarm  
2. Major SHDSL port alarms: LOS, LOSW, or Segment Defect  
3. Minor G.703 port alarms: Rx RAI, Frame Slip, CRC-4 errors, LBER, and any ES, SES, UAS, and CVC 15-Minute  
Threshold Alarm  
If the SHDSL port is selected, press the REMOTE LOOP button to place or remove a remote  
loop on the port by sending a EOC request message to the LTU (or NTU in campus mode). If  
the Nx64K port or G.703 port (with only one service defined) is selected, press this button to  
place or remove a remote loop on the selected port's single data service by sending respective  
inband loop up or loop down patterns to the far end (in the associated data service timeslots).  
4. Major G.703 port alarms: LOS, LOF, LOMF, Rx AIS, or HBER  
5. Nx64K port alarms: Clock Slip, Loss of External Clock, FIFO Underflow/Overflow, and Inactivity Alarm  
BERT  
If a port is selected and there are no local loops, press the BERT button to start or stop a  
BERT on the selected port.
