Notes:  
1. Adaptive linefeed is enabled when the VOCDELTA RAM address is set to a non-zero value and is disabled when  
VOCDELTA is set to 0.  
2. RDC,MAX is the maximum dc resistance of the CPE; hence the specified total loop resistance is RLOOP + RDC,MAX  
.
3. Ringing amplitude is set for 93 V peak using the RINGAMP RAM address and measured at TIP-RING using no series  
protection resistance.
