239 H4R RESISTANCE  
Tip-to-Ring resistance is approximately 6 Ω for each pair (with no power applied).  
z Solid Yellow  
Synchronized with a SNR margin greater than 0 dB,  
but less than the SNR Margin Alarm Threshold  
4 Flashing Yellow  
Synchronized with a SNR margin greater than 0 dB,  
but less than the SNR Margin Alarm Threshold;  
attenuation is greater than the Loop Attenuation  
Alarm Threshold  
LOOPBACK AND CONTROL CODES  
Refer to the Installation and Maintenance Practice of the H4TU-C or H4TU-R used in the  
circuit for a list of loopback codes.  
z Solid Red  
Synchronized with a SNR margin of 0 dB  
HDSL4 LOOP SPECIFICATIONS FOR OPTIMUM OPERATION  
4 Flashing Red  
Flashing once per second indicates synchronization  
with a SNR margin of 0 dB; attenuation is greater than  
the Loop Attenuation Alarm Threshold  
NOTE: The H4TU-Cs (P/N 1221401L6, 1221403L6, 1221404L6) support only one  
repeater in the HDSL4 circuit.  
Refer to the H4TU-C or H4TU-R Installation and Maintenance Practice for loop  
parameters, including Attenuation and Resistance Budgets for span powering.
