VoIP Gateways

Patton (News - Alert), a provider of business and carrier-class network access, connectivity, Voice over Internet Protocol (VoIP) and mobile video-surveillance equipment, announced the launch of two new SmartNode product series for ISDN BRI VoIP users and service providers.

The SmartNode 4120 Single/Dual-Port BRI VoIP gateway and the SN-DTA Singe/Dual-Port BRI VoIP Digital Terminal Adapter are added to the range of NT/TE port combinations available from SmartNode.

“The ISDN market demands exceptional service quality,” said Bernhard Fluehmann, Patton's Converged IP product manager, in a statement. “ISDN users are notoriously picky, yet SmartNode has a strong reputation for high quality among ISDN customers.”

“With our expanded portfolio of BRI VoIP gateways we will satisfy a greater share of ISDN service-provider requirements to meet the true business needs of many more satisfied customers.”

The SN-DTA and SN4120 products include features such as Public Switched Telephone Network (PSTN) fallback, phantom power and high-precision clock that solves VoIP interoperability issues with DECT (News - Alert), PBX, and FAX, company officials said.

The high precision clock (&5ppm) provided with the dual-port SN-DTA/2BIS4VHP enables first-line IP-telephony performance-including reliable fax and modem services-in demanding ISDN and DECT environments.

SN-DTA/2BIS2V offers a fallback port that comes with built-in phantom power. This feature enables the connected ISDN devices to remain powered up in cases where an existing fallback line is removed or the fallback port is not utilized.

The new models also provide replacement options for Patton's S-DTA, SN4552, and SN4554, which are approaching end-of-life, company officials said. Initial shipments of the new products are expected during Q3 and Q4.

Earlier this year, Patton announced the expansion of its SmartNode T1/E1/PRI line of VoIP solutions to include SN4940 Gateway (News - Alert), SN4950 Gateway-Router, and enhanced SN4960 Enterprise Session Border Router (ESBR).
