Small Network Equipment: A device whose primary function is to pass Internet Protocol (IP) traffic among various network interfaces / ports intended for use in residential and small business settings.
Broadband Access Equipment
Broadband Modem: A device that transmits and receives digitally–modulated analog signals over a wired or optical network as its primary function. The Broadband Modem category does not include devices with integrated Router, Switch, or Access Point functionality.
Integrated Access Device (IAD): A network device with a modem and one or more of the following functions: wired network routing, multi–port Ethernet switching and/or access point functionality.
Optical Network Termination Device (ONT): A type of device that converts signals between copper (wired) or wireless connections and an optical fiber connection. ONTs are available in either desktop or building–mounted versions with different connectivity options.
Local Network Equipment
Access Point: A device that provides wireless network connectivity to multiple clients as its primary function. For the purposes of this specification, Access Points include devices providing only IEEE 802.11 (Wi–Fi) connectivity.
Router: A network device that determines the optimal path along which network traffic should be forwarded as its primary function. Routers forward packets from one network to another based on network layer information. Devices fitting this definition may provide both Router functionality and wireless network capability.
Switch: A network device that filters, forwards, and floods frames based on the destination address of each frame as its primary function. The switch operates at the data link layer of the OSI model.

External Proxy Capability: The ability of an SNE device to maintain Full Network Connectivity on behalf of an End Point Device. Must include an implementation of a standard protocol for communicating between the End Point Device and the SNE device. Note: A known such protocol is mDNS. Waking the sleeping End Point Device is typically accomplished by Wake–On–LAN, a wireless equivalent, or some other directed traffic.
Full Network Connectivity: The ability of an End Point Device to maintain network presence while in Sleep Mode or another low power mode (LPM) of equal or lower power consumption and intelligently wake when further processing is required (including occasional processing required to maintain network presence). Presence of the End Point Device, its network services and applications is maintained even though the End Point Device is in a LPM. From the vantage point of the network, an End Point Device with full network connectivity that is in LPM is functionally equivalent to an idle End Point Device with respect to common applications and usage models. Full network connectivity in LPM is not limited to a specific set of protocols but can cover applications installed after initial installation. Also referred to as "network proxy" functionality and as described in the Ecma–393 standard.
- Network Proxy – Base Capability: To maintain addresses and presence on the network while in LPM, the system handles IPv4 ARP and IPv6 NS/ND.
- Network Proxy – Full Capability: While in LPM, the system supports Base Capability, Remote Wake, and Service Discovery/Name Services.
- Network Proxy – Remote Wake: While in LPM, the system is capable of remotely waking upon request from outside the local network. Includes Base Capability.
- Network Proxy – Service Discovery/Name Services: While in LPM, the system allows for advertising host services and network name. Includes Base Capability.
