LCD[1:0]:  
The LCD[1:0] bits represent the 2 bit programmable RDI code generated when a Loss of ATM  
Cell Delineation (LCD) event is detected.  
RDIPRIMID[1:0]  
The RDIPRIMID[1:0] bits specify which two-bit alarm code point (RDI) will be treated as the  
second highest priority code. These bits combined with the RDIPRIHI bits allow almost any  
priority scheme to be specified. The bits are interpreted as shown in RDIPRIHI[1:0]  
The RDIPRIHI[1:0] bits specify which two-bit alarm code point (RDI) will be treated as the  
highest priority code. High priority codes will replace low priority codes at the next transmit  
G1 byte, instead of allowing 10/20 copies to be sent. The highest priority alarm is sent 10/20  
times before replacement is allowed.  
Table 16.  
RDIPRIHI[1:0]  
The RDIPRIHI[1:0] bits specify which two-bit alarm code point (RDI) will be treated as the  
highest priority code. High priority codes will replace low priority codes at the next transmit  
G1 byte, instead of allowing 10/20 copies to be sent. The highest priority alarm is sent 10/20  
times before replacement is allowed.
