Patton’s SmartNode BRI VoIP Line Now Available

GAITHERSBURG, MD: Patton have announced general availability for two new members of the SmartNode family: the SmartNode 4120  Single/Dual-Port BRI VoIP gateway series and the SmartNode DTA Singe/Dual-Port BRI VoIP Digital Terminal Adapter series for ISDN BRI VoIP users and service providers.

Announced June 2011, the SN-DTA and SN4120 product lines are now in full production, as Patton ships hundreds of units on a monthly basis. The new SmartNode SKUs expand the range of NT/TE port combinations and add the following enhanced features: PSTN fallback, phantom power, and a high-precision clock that eliminates common interoperability problems with DECT, PBX, and FAX in VoIP implementations.

  • The new single-port TE gateway (SN4120/1BIS2V) and dual-port NT gateway (SN-DTA/2BIS4V) provide cost-effective solutions for specialized customer applications.
  • The dual-port SN-DTA/2BIS4VHP offers Patton’s high-precision clock, enabling first-line IP-telephony performance with reliable fax and modem services in often-troublesome ISDN and DECT environments. 
  • The SN-DTA/2BIS2V offers a fallback port with built-in phantom power that delivers power to connected ISDN devices whenever the fallback port is not in use or if an existing fallback line is removed.

ISDN users are notoriously picky,” observed Bernhard Fluehmann, Patton’s Converged-IP Product Manager. “Yet SmartNode quality and reliability have earned great respect within the ISDN community. The new BRI solutions are very well received. We expect similar enthusiasm for the new digital-analog hybrid due out soon.

Patton is currently developing an 8-to-24 call VoIP router offering up to 8 BRIs, up to 8 analog FXS/FXO interfaces, and 4 Ethernet ports. The enterprise-class SmartNode is designed to IP-enable legacy ISDN-PBXs, analog phone/fax/answering machines, and/or analog audio-intercom systems with a single device.

Two weeks ago Patton unveiled the SmartNode 10200 carrier-grade VoIP media gateway series, supporting up to 2048 voice or fax calls over T1/E1, DS3 or STM-1/OC3 trunks with SS7 signaling. Last year, Patton expanded the SmartNode PRI gateway line by adding three new model series.
