The SmartNode 5490 Enterprise Session Border Router with built-in WAN broadband access is a single integrated session-border-controller platform that bridges the wide range of IP PBX products to their service providers ensuring security and a high level of efficiency in the VoIP network. Connecting the Enterprise’s LAN to an Internet TelephonyService Provider (ITSP), the SN5490 session border controller creates a single conduit for multimedia components including voice, video and data. Evolving from Patton’s award winningSmartNode 5400 Series, the next generation SmartNode 5490 Series comes now with IPv6 upgradeable hardware.

Through the SIP Back-to-Back User Agent, the SN5490 provides a common interface into the service provider network providing resolution of any differencesbetween the SIP from the IP PBX and the service provider softswitch. Additionally, the SN5490 provides CODEC transcoding for up to 64 SIP sessions insuring themost efficient use of available bandwidth for both voice and data. Reduce WAN-access bandwidth requirements by converting high-bandwidth G.711 calls on yourLAN into lower-bandwidth G.723 calls for WAN transport.

For additional security, the SN5490 includes SIP-aware NAT and access controlled lists (ACLs) for maintaining secure communications when SIP traffic crosses theEnterprise edge. In addition, routing capabilities include RIP v1/v2, virtual router redundancy protocol (VRRP), loopback interfaces as well as advanced techniqueslike policy based routing (PBR). Furthermore, QoS keeps malicious traffic from effecting bandwidth requirements of PBR-marked essential traffic and DownstreamQoS ensures important voice and fax calls do not get bogged down by such resource hungry lower priority TCP traffic as FTP downloads.

For survivability, the SN5490 is equipped with a link status based routing function. This function, together with SIP registrar, enables survivable telephony servicesto be deployed between intra-office SIP clients in case there is a failure at the SIP provider.
