Introduction
Patton’s Smart-DTA Residential VoIP Digital Telephone Adapter provides home and home-office ISDN users
a quick and easy migration path to the cost-saving world of IP telephony. This chapter describes typical appli-
cations for which the Smart-DTA is uniquely suited.
Whether you are connecting to an Internet Telephony Service Provider (ITSP) or the phone system at your
main office, Smart-DTA provides the features you need for high-quality, state-of-the-art Voice-over-IP. In
either scenario, Patton’s robust and mature software provides call-property adaptation with regular-expression
mapping between ISDN and SIP/H.323 signaling schemes. In the corporate private network, intelligent and
configurable call-routing supports existing numbering plans for ultimate useability.
Note
Detailed configuration information for the applications can be found on the
CD-ROM that was included with your Smart-DTA device or online from
the Patton webserver at www.patton.com.
Connect ISDN terminals to an Internet Telephony Service
Provider (ITSP)
Residential users can connect the Smart-DTA’s built-in BRI/NT port directly to an ISDN phone, or to the
ISDN S-bus in the home for two-channel VoIP calling using an ITSP VoIP service. (see
figure 4
).
The Smart-DTA replaces the network terminal adapter while providing an Ethernet connection to the home
LAN for Internet access.
The Smart-DTA supports three types of Internet-access service, including fixed-IP address, DHCP, and
PPPoE.
