1 • System overview
• 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 4 shows the deployment of SmartNodes in carrier networks. Each subscriber site is equipped with a
SmartNode that connects the subscriber CPE on one side with the provider network and services on the other.
Typical services in these networks are softswitch-based telephony, PSTN access through V5.2 gateways, PBX
networking services, and LAN interconnection.
Typical access technologies for these networks include xDSL, WLL, PowerLine, and conventional leased lines.
With the use of an external modem, the SmartNode can connect to leased lines or any bridged-Ethernet broad-
band access.

Enterprise networks

In company-owned and operated wide area networks, SmartNodes can be used to converge voice and data
communications on the same IP link.
In combination with centralized services such as groupware and unified messaging, the SmartNodes provide
migration and investment protection for legacy telephony systems.
