Electrostatic Discharge (ESD) can damage equipment and
impair electrical circuitry. It occurs when electronic printed circuit
cards are improperly handled and can result in complete or intermittent failures. Do the following to prevent ESD:
• Always follow ESD prevention procedures when removing and
replacing cards.
• Wear an ESD-preventive wrist strap, ensuring that it makes good
skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground.
• To properly guard against ESD damage and shocks, the wrist strap
and cord must operate effectively. If no wrist strap is available,
ground yourself by touching the metal part of the chassis.

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 o
ver IP. This enables a PBX analog extension
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.

Application—Private line automatic ringdown (PLAR)
A private hot-line can be created by using two
FXS models back-to-back (see figure 11). These can be found
in use as courtesy phones at ATM’s, information kiosks, and emergency assistance pedestals. In this application, when one handset is picked-up, the remote handset immediately begins
ringing. When the remote
handset is picked-up, the speech path is completed. The end-to-end link supports voice, fax Gr.3 (2.4–14.4
kbps) with T.38 or fax- and modem bypass using a G.711 codec.

Application—Enterprise campus BRI to FXS telephony extension
In combination with the Patton SmartNode 1000 and 2000 Series models the FXS gateways provide ISDN
to FXS extensions over IP (see figure 12).

Application—PBX toll bypass gateway
The gateways can be used to provide toll bypass over an IP WAN (see figure 13). The call routing in this case
is
provided by the PBX systems. A call routed to the FXS gateway can be relayed on a port-to-port basis or

Applications for SmartNode 4520 Series
SmartNode 4520 Series devices have dual 10/100Base-T Ethernet ports. The two Ethernet ports provide full
featured IP routing between LAN and WAN plus Ethernet and IP layer QoS services. Voice prioritization and
traffic management avoid network congestion and provide optimal voice quality. With these additional features
the SmartNode 4520 series can add Internet access and data networking to any of the SmartNode 4110 Series
applications described previously. The following sections show some typical combined voice-data applications.
