Configure IP Header Compression (IPHC)
IPHC reduces the number of bytes transmitted across the WAN, thus 
conserving bandwidth. 
To enable or disable IP header compression, follow the steps below:
1
On the Router Configuration menu (Figure 4.51), type “Q”.
2
The IAD displays the port table and prompts you to enter a port.
3
Type the port number and press Enter. The IAD displays the header 
compression status and prompts you to enable or disable IP Header 
Compression for SDSL.
4
Type “E” to enable IP header compression on this port, or “D” to disable it. 
If you enable IP header compression, the IAD displays a message similar to 
the following:
Springtide Compatibility mode ENABLED (currently not 
selectable)
The IAD saves the changes and displays the Router Configuration menu 
(Figure 4.51). Continue with other configuration tasks, or press Escape to 
return to the Main menu.
