SmartNode Installation

into an IP Network
10.7.3 IP Access to the WAN
In Figure 10-3 through Figure 10-7 a wide area transmission modem is shown as attached to the IP
access network of the operator via Ethernet port ETH 0 for SmartNode 1000 series or ETH 0/0 for
SmartNode 2000 series.
Data traffic from the LAN attached to ETH 1 for SmartNode 1000 series or to ETH 0/1 for SmartNode
2000 series is routed to the WAN via Ethernet ports ETH 0 or ETH 0/0 respectively. Either standard
IP routing or Network Address Port Translation (NAPT) can be configured on the SmartNode
according to requirement.
10.8 ISDN Gateway; LAN based PBX or Call Center Applications
10.8.1 LAN based Telephony Gateways (GW)
The SmartNode 1400 GW depicted in Figure 10-8 is utilized as a LAN Voice Gateway. On the local
LAN that is shown connected to Ethernet port ETH 0, H.323 compliant voice applications are
installed on hosts acting as H.323 terminals. An H.323 terminal is an endpoint in the network that
provides for real-time, two-way communications with another H.323 terminal or gateway.
Outbound voice traffic is forwarded via the integrated voice gateway of the SmartNode 1400 (see
Figure 1) to the PSTN. Inbound voice traffic from the PSTN is terminated on the respective host
running the H.323 compliant client application according to the dialed calling number.
The H.323 gatekeeper is responsible for the translation of IP addresses into E.164 phone numbers and
vice versa. Note that hosts on the local LAN need to be connected to Ethernet port ETH 0 using a
hub.
