Configuration roadmap
The configuration roadmap is as follows:
1. Create the channel.
2. Create the bound group.
3. Configure the channel to join the bound group.
Data preparation
To configure the CPOS interface, you need the following data:
• Channel number and slot number of each E1 channel
• Number of the bound group on each interface
CD
NOTE
• The numbering of the Mp-group interfaces of the Secure Router 8000 follows certain limitations.
The slot number and card number must be 0.
• The interfaces added to the MP-group can only be the physical interfaces or the serial interfaces
instead of other interfaces.
Configuration procedure
CQ NOTE
• High-speed CPOS interfaces support MP binding only when the E1/T1 channels are working in the
clear channel mode.
• The MP binding mode of the high-speed interface is different from that of the low-speed interface.
Choose the following configurations as required:
• For the low-speed CPOS interface, do as follows:
