Application—Analog line extension over IP
A virtual analog line can be created using an FXO and FXS model (see figure 9 ). The complete signaling and
media (voice, fax, or modem) of the analog phone line is extended over IP. This enables a PBX analog exten-
sion line to be extended to a home office or satellite office. The analog line extension relays DTMF, hook-flash
and CLI to provide full PBX feature access over the IP network (checking voice mail or joining a calling group,
for example).

Application—ITSP dial-in access
An ITSP can use the SmartNode FXO gateways as dial-in access points to his Internet telephony services (see
figure 10 ). A user calls a local number, the FXO SmartNode picks up the call and uses a second dial-tone to
dial the remote number. The system can be enhanced with a central call control server providing IVR
announcements, PIN checking, and accounting for the calls.
