Parameter Value Remarks
T-CONT It is recommended that the number
of T-CONTs do not exceed 3. The
T-CONT ID ranges from 1 to 3.
It is recommended that all E1 lines
of the same ONU use the same T-
CONT.
DBA type Fixed bandwidth and minimum
delay
The DBA must be configured
properly to achieve low delay, low
jitter, and zero packet loss so that
the quality of the T1 base station
access service can be ensured.
DBA bandwidth
l E1 access: Nx8 Mbit/s is
recommended. (N is the
number of E1 lines.)
l T1 access: Nx6 Mbit/s is
recommended. (N is the
number of E1 lines.)

Enterprise E1/T1 unified access (OLT Cascading)
The QoS policies for this scenario are the same as those for the Enterprise E1/T1 unified
access scenario.
13.2.4 Principle of Protocol Transparent Transmission Data Plan
The enterprise access service involves transparent transmission of protocol packets. Different
equipment configurations are required for transparently transmitting different protocol packets.
Configurations for Protocol Transparent Transmission
Protocol Type Protocol Description Configuration (remarks 1)
BPDU STP, MSTP, RSTP, IS-
IS
The function of transparently transmitting
BPDU packets must be enabled.
Configuration example:
huawei(config)#vlan service-profile
profile-id 1
huawei(config-vlan-srvprof-1)#bpdu
tunnel enable
ETH OAM IEEE 802.1ag No configuration is required because packets
are transparently transmitted by hardware.
Broadcast ARP No configuration is required because packets
are transparently transmitted by hardware.
Layer 2/Layer 3
protocol
NTP, BGP, LDP, RSVP,
IGMP, PIM
No configuration is required because packets
are transparently transmitted by hardware.
