The Type of Service or “TOS” field

01234567

PRECEDENCE D T R

unused

The three precedence have eight values, 0-7, ranging from “normal” precedence (value of 0) to “network control”

(value of 7). When set, the D bit requests low delay, the T bit requests high throughput, and the R bit requests

high reliability.

Routers that support DiffServ can examine the six DSCP bits and prioritize the packet based on the DSCP value.

The Diff Serv Parameters fields in the IP Parameters screen allow you to configure the DSCP bits to values

supported by the router. Specifically, the Voip Media PHB field relates to the prioritizing of audio packets (RTP

and RTCP packets) and the Call Control PHB field relates to the prioritzing of non-audio packets (packets

concerning call set-up and tear-down, Gatekeeper registration, etc.).

The Call Control PHB parameter defaults to 34 decimal (22 hex; 100010 binary – consider vis-à-vis TOS field

above) for Assured Forwarding behavior. The Voip Media PHB parameter defaults to the value 46 decimal (2E

hex; 101110 binary – consider vis-à-vis TOS field above). To disable Diff Serv, configure both fields to 0 decimal.
