For the Internet Service Providers or Enterprises that need a high precision clock source for DECT or legacy ISDN PBXs, the SmartNode 4961 High Precision models provide a cost effective solution with superior interoperability and VoIP functionality. High Precision SmartNode 4961 models are capable of providing Stratum III 5 ppm clock for those ISDN PBXs that normally rely on PSTN clock accuracy. High precision models also greatly improve the fax performance when both transmit and receiving ends are synchronized to high precision clock sources. Like standard SN4960s, the SN4961 is ideal for PBX business trunking or corporate VoIP access. Offering up to four software configurable T1/E1/PRI interfaces the SN4961 connects to any switch, PBX and data network with up to 120 simultaneous calls using SIP, T1, E1 or PRI signaling. The dual gigabit Ethernet ports connect to the network for the highest throughput with its integrated QoS router. With its built-in CSU/DSU, any T1/E1 port can be selected as a WAN port for truly integrated voice and data access.

Patton SmartNode SN4961/1E24V/UI – 1 T1/E1/PRI VoIP IAD, 2x GigEthernet, 24 VoIP Channels, upgradeable to 30, Internal UI Power, High Precision Timing.

Like every SmartNode, the SN4960 delivers toll-quality voice with all industry standard CODECs including low-bandwidth G.723/G.729. Business class services are supported with T.38 fax, fax bypass and modem bypass features.

Many business class features are provided in the SmartNode 4960 product line, including Failover Relay for increased call reliability. Multi-link PPP and Frame Relay are provided as configurable software options for customers who need to bond E1/T1 lines. An X.21 WAN port is also available for serial WAN services.

The SmartNode 4960 is ready for SIP TLS and SRTP through software upgrades. Exclusive DownStreamQoS and Voice-over-VPN features give the clear advantage of uninterrupted and secure voice communication for any call today.
