Sequenced Predictor Compression
Packet data can be compressed to provide better throughput across slower
WAN links. Sequenced Predictor is a compression algorithm used in some
Compatible Systems routers.
If checked this router will compress packet data being sent on this inter-
face using the Sequenced Predictor algorithm.
v Note: A general rule of thumb for Compatible Systems routers would be to
use Sequenced Predictor on uncompressed links at up to 128K rates, but to
turn it off at higher speeds or if other means of compression (such as the V.42
compression built into modems) are in use. A few simple file copy transfer
tests over your particular WAN setup will yield a more exact answer.
PPP Link Quality Configuration Dialog Box
PPP Link Quality Configuration Dialog Box
You can access the PPP Link Quality Configuration Dialog Box by selecting
On Demand PPP Link or Dedicated PPP Link from the Link Type pull-
down in the Link Configuration: WAN Dialog Box (under WAN/Link
Configuration), and then clicking on the PPP Options button at the bottom
of the dialog box, and then clicking on the Link Quality button at the bottom
of the PPP Options Dialog Box.
This dialog box is used to set parameters which allow a router using PPP to
monitor the quality of an on-demand WAN link. If poor link quality is
detected, the line can be dropped and redialed to improve performance.
> Echo Packets On
This checkbox controls whether this router will use an echo protocol to
monitor the quality of the line.
