5.1.3

Priority Control

Some routers permit the configuration of priority control features. This allows the router to be 
configured to give higher priority to packets with high priority flags. The priority control feature 
should be used when available. 

To configure, please refer to Section 4.9.1 Configure Gateway Units (KX-TDA0480) of IP 
Gateway Card Installation Manual.

5.1.4

Recovery Delay and Jitter Buffer

When voice signals are packetised and transmitted, individual packet can take different paths 
through the network and arrive at the destination at varied timings (Jitter). The IP Gateway 
Card supports a secondary Jitter Buffer (max. 1920 ms) in which the packets are accumulated 
temporarily for processing to compensate for network congestion problems.

To configure, please refer to 4.9.1 Configure Gateway Units (KX-TDA0480) of IP Gateway 
Card Installation Manual.

5.1.5

Internet, Intranet, and Virtual Private Networks (VPN)

Manageable networks (e.g., Intranet, Leased Lines, VPN) provide better quality of service 
compared to unmanageable networks such as the Internet. 

When implementing a VoIP network, care must be taken when assessing bandwidth 
requirements. The IP Gateway Card uses 12 k per port when in use. Serialisation delays to the 
WAN are lower when higher bandwidths are used. 

When using the Internet/VPN, the ISP plays an important role in reducing the variable delay in 
the WAN. A regional or national ISP will usually have better connectivity with the backbone and 
will be able to guarantee greater service reliability than a local city ISP. When using VPN 
facilities, delays may be introduced due to the additional processing time required for 
encryption processing.
