Tx Payload Type Machine Status 0x200+n*4
Bits Data Element Name R/W
Reset
Value
Description
[1] Tx_HDLC_align_err R/W None HDLC – received frame from TDM with alignment error
[0] Tx_AAL1_framing_mismatch /
Tx_HDLC_CRC_err /
Tx_SAToP/CESoPSN_framing_
mismatch
R/W None AAL1 – Start of TDM frame or start of TDM multiframe
mismatch
HDLC – received frame from TDM with CRC error
SAToP/CESoPSN – Start of TDM frame or start of TDM
multiframe mismatch
Tx Buffers Status 0x400+n*4
Bits Data Element Name R/W
Reset
Value
Description
[31:1] Reserved - None Must be set to zero
[0] TDM_to_ETH_buff_err R/W None Frames received from TDM were discarded due to lack of
Tx buffers
Packet Classifier Status 0x600+n*4
Bits Data Element Name R/W
Reset
Value
Description
[31:8] Reserved - None Must be set to zero
[7] Packet_length_error R/W None Packet discarded due to mismatch between IP_length/
Control_word_length (for MPLS/MEF) and the actual
length according to the following rules:
IP packets – If IP_length > (actual payload + ip_hdr + CW
+ RTP)
MPLS/MEF packets – If Control_word_length > actual
payload length + CW + RTP
[6] Rx_sync_loss RO None received packet with “L” indication
[5] Rx_remote_fail RO None received packet with “R” indication
[4:3] Rx_Lbit_modifier RO None received packet with “M” indication
[2:1] Fragmentation_bits RO None Relevant for SAToP/CESoPSN payload type machine:
00 = Entire (unfragmented) multi-frame structure is carried
in a single packet
01 = Packet carrying the first fragment
10 = Packet carrying the last fragment
11 = Packet carrying an intermediate fragment
[0] Rx_length_mismatch_discard R/W None Packet discarded due to mismatch between the packet
length and the configuration (for AAL1 and SAToP/
CESoPSN bundles only)
11.4.4.2 Per JBC Index Tables
In the register descriptions in this section, the index n indicates the jitter buffer number: 0 to 255.
Rx JBC Status 0xC00+n*4
Bits Data Element Name R/W
Reset
Value
Description
[31:1] Reserved - None Must be set to zero
[0] JBC_overrun R/W None AAL1 – overrun has occurred
HDLC – overrun has occurred
SAToP/CESoPSN – overrun has occurred
