ISDN telecommuter connection to a PBX via a corporate-
private network
For a SoHo/telecommuter, the Smart-DTA can provide a home-office extension to the ISDN PBX at the cor-
porate headquarters. The S-DTA routes the ISDN calls through the corporate-private network (see
figure 5
)
using Voice-over-IP, so a home user avoids toll charges when making calls to headquarters. Remote users can
make and receive calls as though located in the main office, with all the calling features and services available to
callers connected directly to the PBX (such as station-to-station dialing, outside trunk access, and voice mail).
