CLAN and processor CLAN QoS and CIDR support
Issue 5 October 2002 1637555-233-506
CLAN and processor CLAN QoS and
CIDR support
Previous IP packet addressing and routing procedures for the TN799
Control-LAN circuit pack have not always been compatible with Avaya
MultiVantage customers’ evolved networks. Quality of Service (QoS) features are
necessary to provide superior call quality for voice-over-IP (VoIP) signaling.
Although classful IP addressing structures were used in the beginning of VoIP
development, enhancing C-LAN support of Classless Inter-Domain Routing
(CIDR) and the closely-related Variable Length Subnet Mask (VLSM) paradigms
provide the Avaya MultiVantage platforms with enhanced IP addressing and
routing flexibility, while ensuring customer-network compatibility.
Configurations/Platforms
To use CIDR and IP QoS, the TN799DP Control-LAN circuit pack is required for:
■ Avaya Media gateways (DEFINITY CSI, DEFINITY SI, DEFINITY R,
S8700 Media Server, and S8700 Media Server)
■ Avaya™ S8100 Media Servers
To use CIDR and IP QoS, the TN799DP C-LAN circuit pack is not required for:
■ S8300 Media Server
The S8300 Media Server uses the its processor CLAN feature. The S8100 Media
Server with a CMC1 and S8100 Media Server with a G600 can use either its
processor CLAN feature or a TN799DP Control-LAN circuit pack.
