NOTE
You can also create a SAToP connection by configuring the MAC address statically. If the remote MAC address
(the MAC address of the EDTB board on the OLT) is 0800-3E32-5310, create a SAToP connection in static
mode as follows:
huawei(config)#cesop-connect tdm 10 vlan 300 local-udp 50048 remote-mac
0800-3E32-5310 remote-ip 10.10.50.10 remote-udp 50048
Step 4 (Optional) Configure attributes of the SAToP connection.
NOTE
The attributes of the SAToP connection on the OLT must be consistent with those on the ONU. Generally, use
the system default values.
l Run the cesop rtp command to configure whether the SAToP packet carries the RTP header.
The SAToP packet carries the RTP header by default.
l Run the cesop encap command to configure SSRC, payload type, and SN of the SAToP
packet. The default value of these parameters is 0.
l Run the cesop jitter-buffer command to configure the buffer depth of the SAToP packet.
The default buffer depth is 2000 μs.
l Run the cesop loadtime command to configure the load time of the SAToP packet. The
default load time is 125 μs.
l Run the cesop priority command to configure the priority of the SAToP packet. The default
priority is 7.

ONU
Issue 01 (2014-04-30)
OLT_A traces the upstream E1/T1 line clock of the EDTB board as the system clock.
OLT_B Obtains the system clock by GICK/X2CS boards in synchronous Ethernet mode.
The ONU uses the line clock of the GPON upstream port as the system clock.
The Tx clock of ONU is synchronized to the system clock of the ONU.

Description
OLT_A Obtains E1/STM-1 line clock from SDH as
the system clock. and then transmits it to the
cascading OLT_B over GE/10GE interface.
OLT_B Obtains the system clock in synchronous
Ethernet mode. The clock is transmitted to the ONU
over the GPON line.
