The SmartNode 4630 series consists of two models: the SN4634 and SN4638. Both models come equipped with two 10/100Base-T Ethernet ports.

The SmartNode 4638 Gateway-Router performs the following major functions:

•Eight channels of Voice over IP and local voice switching via 5 ISDN BRI S0 ports. Each port can be switched between NT and TE per software. One port can be used a clock source.

•For each ISDN S0 port in NT mode a Phantom power supply can be switched on. The total delivered power is 4W.

•A fallback cut-through relay between ISDN BRI ports 0/0 and 0/1 electrically connects the NT and TE port in case of power failure and enables life-line calls to the public ISDN network (PSTN-supplied ISDN line must be used).

•Standard compliant VoIP in accordance with SIP or H.323 protocols.

•Internet access and IP Routing with IP Quality of Service (QoS) support for mixed voice and data traffic. The SN4634 is the same as the SN4638 except that it supports 3 ISDN BRI S0 ports and 4 VoIP channels.
