SmartNode 4400 Series applications
SmartNode 4400 Series devices have dual 10/100Base-T Ethernet ports. The two Ethernet ports provide full
featured IP routing plus Ethernet and IP layer QoS services. Voice prioritization and traffic management avoid
network congestion and provide optimal voice quality. The following sections show two typical converged
voice-and-data applications.
Like all members of the SmartNode family of VoIP solutions, the SmartNode 4400 Series supports all indus-
try-standard VoIP signaling protocols, including SIP, H.323, T.38 fax-relay, plus fax- and modem-bypass. The
SmartNode 4400 is interoperable with leading softswitches and VoIP servers
Enterprise FXS concentration and extension over IP and T1/E1
The SN4400 Series IpChannel Bank can be used with a T1/E1 gateway to extend a T1 or E1 line over IP and
split it into FXS ports—providing operators and enterprise network administrators with a simple and cost-
effective option to provide a large number of FXS ports in a remote location (see figure 4).
