Patton Releases Carrier-Grade BRI VoIP Adapter for ISDN SOHO and Residential Markets


Connecting ISDN phones to any VoIP system, the award-winning SmartNode™ S-DTA is the only two-call VoIP CPE on the market suitable for carrier-network deployment.

SmartNode™ VoIP... more than just talk.

BERN, SWITZERLAND: Patton-Inalp Networks—creator of the SmartNode™ brand of industry-leading VoIP technology solutions—announces their award-winning SmartNode™ Smart-Digital Telephone Adapter (S-DTA) is fully released and generally available.
As the only two-call ISDN VoIP CPE on the market that runs carrier-grade software— Patton’s SmartWare™—the S-DTA is the obvious choice for double and triple-pay service providers seeking an ISDN termination device. With touchless auto-provisioning and proven reliability in numerous carrier deployments, SmartWare™ offers proven interoperability with all major-brand softswitches and IP-PBXs.
Designed for deployment in ISDN homes and small offices, the device supports two concurrent voice or T.38 fax calls (Super G3 and V.34 capable). The very-low-cost, feature-rich S-DTA seamlessly connects up to 8 ISDN terminals over the S-bus to a service provider or private VoIP network.

Service providers can use the S-DTA to roll out profitable Internet-telephony, double-play, and triple-play services in the demanding ISDN residential market. Built-in So line power reduces overall CPE costs by eliminating the need for an external power supply.

Subscribers can enjoy the cost-saving benefits of VoIP technology using their existing ISDN terminals (up to 8 phones). The device’s powered So port connects to the S bus in the subscriber’s home or office.
Enterprises and integrators can use the S-DTA to seamlessly extend corporate PBX services to remote and home-office workers. Number plan adaptation, inter-protocol mapping, and other advanced features ensure users can communicate they way they’re used to—but without the high PSTN charges.

“This market demands a high standard of quality,” said John Wu, Product Manager. “ISDN users are extremely picky. With the S-DTA, the only thing ISDN callers will miss is the big phone bill.”
The advanced VoIP technology in SmartNode™ equipment preserves all the ISDN telephony features that ISDN users depend on and network operators require (AOC, CLIP, CLIR, UD64, overlap dialing, and fax, as well as MSN and DID). Built on the industry’s most interoperable VoIP platform, the SmartNode™ S-DTA supports ISDN, SIP, H.323, and MGCP/IUA signaling.

Patton’s S-DTA won INTERNET TELEPHONY magazine’s ( 2007 Product of the Year, the third consecutive year SmartNode won the award.
