IEEE P802.3av 10GEPON Task Force

Baseline Proposals

# Feature Details Motion Reference File
March 2007
1 Accommodation of FEC overhead 10GEPON shall accommodate FECís parity bandwidth by reducing the MACís effective data rate (sub-rating). See Motion 3
2 Upstream FEC framing and synchronization Accept the scheme outlined in slides 3-7 in 3av_0703_mandin_2.pdf as the baseline scheme for upstream FEC framing and synchronization. See Motion 4 3av_0703_mandin_2.pdf
3 Downstream FEC codeword structure Accept as a baseline scheme the FEC codeword structure depicted in the illustration on slide 5 in 3av_0703_mandin_2.pdf for the downstream (so that the FEC codeword structures on the upstream and downstream are identical). See Motion 5 3av_0703_mandin_2.pdf
4 P802.3av document structure The 802.3av Task Force approves the creation of two clauses as presented in 3av_0703_remein_1.pdf slides 7, 8, & 9. Outline of the clauses may be modified as necessary. See Motion 6 3av_0703_remein_1.pdf
5 10G/1G coexistence using upstream TDMA at 1310 For the 10GEPON upstream, the TDMA at 1310nm coexistence method is conditionally selected as baseline, unless technically and economically feasible link budgets cannot be found for all cases. See Motion 7 3av_0703_effenberger_4.pdf
May 2007
6 10 Gbps upstream signal 10 Gbps upstream signal to have a pass band of 20 nm. See Motion 3 3av_0705_tanaka_1.pdf (slide 14)
7 Handling of XAUI errors 802.3av shall not support a physical XAUI interface between PHY and MAC in the ONU. See Motion 5
8 FEC Codeword Structure The FEC algorithm shall accept as its input Nx65bit payloads (the second bit of the sync header plus 64 bits of data) pre-pended with padding consisting of zeros to bring the input codeword to the required size; notwithstanding, both bits of the sync header shall be transmitted, while the padding shall not be transmitted, as illustrated in 3av_0705_effenberger_4.pdf. See Motion 6 3av_0705_effenberger_4.pdf
9 FEC Framing To accept as a baseline for FEC framing the presentations 3av_0701_effenberger_1.pdf, 3av_0703_kramer_1.pdf, and 3av_0705_lynskey_1.pdf. See Motion 7 3av_0701_effenberger_1.pdf
July 2007
10 10G Broadcast MAC There shall be a Broadcast MAC instance for 10G distinct from the 1G Broadcast MAC instance See Motion 3
11 Upstream power budget target For the B++ case, adopt a baseline proposal for the upstream specifications corresponding to an APD with high output power DML. See Motion 8
12 Start-of-Packet Alignment Idle Deletion State machine should align /S/ character of the first frame in the burst to the byte-0 position as shown in FSM1 on slide 7 in 3av_0707_kramer_1.pdf. See Motion 9 3av_0707_kramer_1.pdf
13 Idle Insertion Adopt as a baseline proposal the idle insertion mechanism set forth in 3av_0707_lynskey_2.pdf. See Motion 10 3av_0707_lynskey_2.pdf
14 10G upstream wavelength 10Gbps upstream signal shall be centered at 1270 nm for all power budget classes. See Motion 12
15 Broadcast MAC LLIDs Each broadcast MAC instance shall be associated with a unique LLID. The 10G broadcast channel shall be associated with LLID 0x7FFE. The 1G broadcast channel shall be associated with LLID 0x7FFF. The ONU transmits REGISTER_REQ with an LLID according to its upstream rate. A 10G/1G ONU receives broadcasts on LLID 0x7FFE and REGISTER_REQ to 0x7FFF. See Motion 22 3av_0707_mandin_3.pdf
