l
The VoIP services of user M and user N are sent to the transmission network at NE2 and
NE4 respectively and to the VoIP server at the convergence node NE1. The services share
a 20 Mbit/s bandwidth.
l
The HSI services of user M and user N are sent to the transmission network at NE2 and
NE4 respectively and to the HSI server at the convergence node NE1. The services share
a 40 Mbit/s bandwidth.
l
The VoIP services need to be isolated from the HSI services.
l
The data communication equipment of user M and user N provides 100 Mbit/s Ethernet
electrical interfaces of which the working mode is auto-negotiation, and does not support
VLAN.
–
C-VLAN ID of the VoIP services: 10
–
C-VLAN ID of the HSI services: 20
NOTE
The application scenarios where one branch needs to communicate with other branches are as follows:
l
User M needs to communicate with user N.
l
User M need not communicate with user N.
If user M and user N need to communicate with each other, skip
Spoke attributes of ports connected to the bridge.
Requirement of the operator: The operator requires that all services received from the user side
should be uniformly labeled and groomed through planned S-VLANs.
l
S-VLAN ID of the VoIP services: 100

S-VLAN ID of the HSI services: 200
