Bit #
Name
Default
Bit 0/Receive SS7 Fill-In Signal Unit Delete (RSFD)
Bits 1 to 5/Unused, must be set to 0 or proper operation
Bit 6/Receive HDLC Mapping Select (RHMS)
Bit 7/Receive HDLC Reset (RHR). Resets the receive HDLC controller and flushes the receive FIFO. Must be
cleared and set again for a subsequent reset.
0 = normal operation; all FISUs are stored in the receive FIFO and reported to the host.
1 = When a consecutive FISU having the same BSN the previous FISU is detected, it is deleted without
host intervention.
0 = receive HDLC assigned to channels
1 = receive HDLC assigned to FDL (T1 mode), Sa bits (E1 mode)
0 = normal operation
1 = reset receive HDLC controller and flush the receive FIFO
