Configuration

The following configuration task list details the necessary steps to enable QoS configuration and IPNC systems. QoS interoperation with Third party router relies on the successful negotiation of the PPP protocol options.

QoS interoperation with 3rd Party routers

IPNC 3.2 software has the following operating characteristics

Description

Value

Voice UDP port numbers range

0xC000 to 0xCFFF

Signalling TCP port number

1720

DSCP (TOS/Diffserv) value

0xA0

The “enabling protocols” for low speed WAN links is the PPP options for IP Header Compression (RFC 2508) and PPP Multilink (RFC1990). As long as these options are agreed on the PPP link then each router can “locally” apply QoS to their respective end of the link.

The DSCP value is configured on the system/gatekeeper tab and the PPP multilink and IPHC option is configurable under the Service/PPP tab.

Step 4 - Test IP Connectivity

The IPNC Monitor Tool is a powerful debugging and diagnostic tool. Using the IPNC System Monitor application options, it is possible to debug all aspects of the IPNC's functions and features. Generally, outputs are associated directly to any related standard. E.g. PPP monitor outputs will reference RFC terms relating to the PPP protocol.

The section IPNC debugging contains details on further monitor options useful for debugging QoS, call setup and protocol negotiations issues on IPNC.
