Value
Description
[31:22] Rx_max_buff_size R/W None
The size of the jitter buffer. See section 10.6.10. Also the
maximum time interval for which data is stored. The
resolution is determined by the interface type as follows:
For framed E1/T1: 0.5 ms.
For unframed E1/T1 or serial bundles: 1024 bit periods
For high-speed interface: 4096 bit periods.
Allowed values:
For T1-SF: Rx_max_buff_size
≤
0x2FC
For T1-ESF: Rx_max_buff_size
≤
0x2F9
For E1-MF: Rx_max_buff_size
≤
0x3FB
For all interface types, the Rx_max_buff_size must be
greater than Rx_PDVT + PCT (Packet Creation Time).
Note: For unframed, the Rx_max_buff_size resolution is
different than PDVT resolution.
[21:20] Payload_type_machine R/W None
00 = HDLC
01 = AAL1
10 = Reserved
11 = SAToP/CESoPSN
[19]
Tx_RTP
(Tx is toward Ethernet MAC)
R/W None
0 = RTP header does not exist in transmitted packets
1 = RTP header exists in transmitted packets
[18] Control_Word_exists R/W None
0 = Control word does not exist
1 = Control word exists (default, standard mode)
[17:16] Tx_dest R/W None
Destination of packets:
00 = Reserved
01 = Ethernet
10 = CPU
11 = TDM (Cross-connect). See section 10.6.11.10.
[15:9] Rx_max_lost_packets R/W None
The maximum number of Rx packets inserted upon
detection of lost packets
[8:4] Number_of_ts R/W None
One less than number of assigned timeslots per bundle.
When Rx_AAL1_bundle_type=’00’ (unstructured) then
Number_of_ts=31; this applies also to high speed mode.
[3] Rx_ discard_sanity_fail R/W None
0 = Discard AAL1 packets which fail the sanity check
1 = Don’t discard the above packets
See section 10.6.13.8.
[2:1] Header_type R/W None
00 = MPLS
01 = UDP over IP
10 = L2TPv3 over IP
11 = MEF
[0] Tx_R_bit R/W None
0 = Don’t set R bit in header of transmitted packets
1 = Set R bit

0 = Regular operation
1 = Use conditioning octet specified by
Tx_cond_octet_type for transmitted packets
[29] Tx_dest_framing R/W None
Only applies to T1 framed traffic. See section 10.6.5.
0 = Destination framer operates in SF framing
1 = Destination framer operates in ESF framing
[28] Tx_CAS_source R/W None
Source of transmit CAS bits:
0 = TDMoP block’s RSIG input
1 = Tx software CAS table (section 11.4.9)
