IPHC reduces the number of bytes transmitted across the WAN, thus
conserving bandwidth.
To enable or disable IP header compression, follow these steps:
1. On the Router Configuration menu, type Q.
2. The IAD displays the port table and prompts for a port:
Port VPI VCI Encapsulation Type PCR Service
1 0 40 RFC 1483 (with LLC Encap)3641 UBR
Total = 3641 cps
Maximum PCR this interface can support = 3622 cps
Select Port: [1-8]
Type the port number and press Enter.
3. The IAD displays the header compression status and prompt:
IP Header Compression for SDSL, Port 1 is currently
DISABLED
Enter E to Enable, D to Disable:
Type E to enable IP header compression on this port, or D to disable it.
If you enable IP header compression, the IAD displays the following
message:
Springtide Compatibility mode ENABLED (currently not
selectable)
The IAD saves the changes and displays the Router Configuration
menu.
4. Continue with other configuration tasks, or press Escape to return to
the Main menu.
5. Reset the IAD (page 15) when you finish configuration.
