Applications
The Patton SmartNode product family consists of highly flexible multi-service IP network devices, which fit a
range of networking applications. This section provides an overview of the following SmartNode applications
and the main elements in a SmartNode network.
• Carrier networks—SmartNodes are used as customer gateways or integrated access devices at the customer
premises. These applications are also called Integrated Service Access (ISA).
• Enterprise networks—SmartNodes are used as WAN routers and voice gateways for inter-site networking.
These applications are also called multiservice intranets (MSI).
• LAN telephony—SmartNodes serve as gateways between the LAN and the local PBX or PSTN access.
These applications are also called LAN voice gateway (LVG).
Carrier networks
The network termination (NT) device in a multi-service IP based provider network plays a vital role. It pro-
vides the service access point for the subscriber with respect to physical connectivity and protocol interopera-
bility.
Since the access bandwidth in most cases represents a network bottleneck, the NT must also ensure traffic clas-
sification and the enforcement of service level agreements (SLA) on the access link. In broadband access net-
works, this NT is also called an Integrated Access Device (IAD) or customer gateway.
SmartNode products offer unique features as customer gateways for business services. It provides amongst oth-
ers full ISDN feature support, local switching and breakout options and mass provisioning support.

Figure 2 shows the deployment of SmartNodes in carrier networks. Each subscriber site is equipped with a
SmartNode that connects the subscriber LAN on one side with the provider network and services on the other.
