28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
through 1, function as a 32 bit counter, which is incremented anytime the Receive STS-1/STS-3 TOH Processor block
detects a Line - Remote Error Indicator event within the incoming STS-1 or STS-3 data-stream.

OTES
:
1.
If the Receive STS-1/STS-3 TOH Processor block is configured to count REI-L events on a per-bit basis,
then it will increment this 32 bit counter by the nibble-value within the REI-L field of the M0 byte (or the
contents within the M1 byte) within each incoming STS-1 (or STS-3) frame.
2.
If the Receive STS-1/STS-3 TOH Processor block is configured to count REI-L events on a per-frame
basis, then it will increment this 32 bit counter each time that it receives an STS-1 or STS-3 frame that
contains a non-zero REI-L value.
BIT [7:0]Filtered/Accepted K1 Byte Value
These READ-ONLY bit-fields contain the value of the most recently filtered K1 byte value that the Receive STS-1/STS-
3 TOH Processor block has received. These bit-fields are valid if the K1/K2 pair (to which it belongs) has been received
for 3 consecutive STS-1 or STS-3 frames.
This register should be polled by Software in order to determine various APS codes.
BIT [7:0]Filtered/Accepted K2 Byte Value
These READ-ONLY bit-fields contain the value of the most recently filtered K2 Byte value that the Receive STS-1/STS-
3 TOH Processor block has received. These bit-fields are valid if the K1/K2 pair (to which it belongs) has been received
for 3 consecutive STS-1 or STS-3 frames.
This register should be polled by Software in order to determine various APS codes.
BIT [7:0] - Filtered/Accepted S1 Byte Value
These READ-ONLY bit-fields contain the value of the most recently filtered S1 byte value that the Receive STS-1/STS-
3 TOH Processor block has received. These bit-fields are valid if it has been received for 8 consecutive STS-1 or STS-
3 frames.
