Smart-DTA Residential Digital Telephone Adapter

Model S-DTA

The S-DTA brings all advantages of VoIP to ISDN users. It connects multiple terminals to its
BRI So bus, and converts 2 concurrent voice or fax calls to SIP or H.323 —at an incredibly
low price.

The Smart-DTA enables integration of ISDN network users

into a local VoIP phone service, or extends an ISDN line of

a PBX to a remote site over IP. It offers a simple end-user

configuration interface and connects both to a PBX in point-

to-point mode and an So bus in point-multipoint mode.

Unlike most other products on the market, Patton’s intelli-

gent call routing technology does not only offer simple ISDN

to VoIP, but also advanced features like number plan adap-

tations, mappings between ISDN and SIP/H.323, manipu-

lation of call properties through regular expressions, routing

calls based on time-of-day or bearer capability criteria and

much more.

Providing power to the ISDN line, the S-DTA eliminates the

need for an external power supply to provide power to the

terminals. Gateway functions use standard CODECs such as

G.723, G.729, and T.38 fax as well as industry standard

SIP, H.323 and MGCP/IUA signaling protocols to ensure

seamless connection and compatibility for all voice services.

Quality of service (QoS) features complete the offering with

advanced voice prioritization and traffic management includ-

ing VLAN and 802.1p/Q tagging.
