Table 4-3. HDSL Receive Write Registers
Three identical groups of write-only registers configure the HDSL receivers, and control the mapping of HDSL
payload bytes into the receiver elastic stores (RFIFO). Configuration registers define each HDSL receive
framer’s criteria for loss and recovery of frame alignment by selecting the number of detected SYNC word
errors used to declare loss of sync or needed to acquire sync. Refer to the Framer Synchronization State
Diagram,
