SN5481/32P/EUI - SmartNode eSBC, 32 transcoded SIP Sessions (SIP b2b UA) upgradeable only for non transcoded SIP calls (max. 80)
by PATTON

The Patton Model SN5481-32P-EUI Enterprise Session Border Controller + Router is a high performance solution that bridges a 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 Telephony Service Provider (ITSP), the SN5480 creates a single conduit for multimedia components including voice, video and data. Evolving from Patton’s award winning SmartNode 5400 Series, the next generation SmartNode 5480 Series comes now with IPv6 upgradeable hardware.

Through the SIP Back-to-Back User Agent, the SN5480 provides a common interface into the service provider network providing resolution of any differences between the SIP from the IP PBX and the service provider softswitch. Additionally, the SN5480 provides CODEC transcoding for up to 64 SIP sessions insuring the most efficient use of available bandwidth for both voice and data. Reduce WAN-access bandwidth requirements by converting high-bandwidth G.711 calls on your LAN into lower-bandwidth G.723 calls for WAN transport.

For added security, the SN5480 includes SIP-aware NAT and access controlled lists (ACLs) for maintaining secure communications when SIP traffic crosses the Enterprise edge.

In addition, routing capabilities include RIP v1/v2, virtual router redundancy protocol (VRRP), loopback interfaces as well as advanced techniques like policy based routing (PBR). Furthermore, QoS keeps malicious traffic from effecting bandwidth requirements of PBR-marked essential traffic and Downstream QoS 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 SN5480 is equipped with a link status based routing function. This function, together with SIP registrar, enables survivable telephony services to be deployed between intra-office SIP clients in case there is a failure at the SIP provider.
