The Access Gateway provides an access interface between multiple types of line side services and devices and the packet network. Examples of these services and devices are Plain Old Telephone Service (POTS) telephones, Basic Rate Interface (BRI) sets, Coin telephones, as well as some Digital Subscriber Line (DSL) and private lines/special services on 2 and 4 wire DS0, DS1 interfaces,… (Read More →)

Historically, one of a set of gateways (routers) operated by the Internet Network Operations Center at BBN.
Note: The core gateway system forms a central part of Internet routing in that all groups must advertise paths to their networks from a core gateway, using the exterior gateway protocol (EGP). [Bahorsky]

A device implementing the Delivery Network Gateway Function. The DNG may also be termed the RG (Residential Gateway) in other standards bodies.

Synonym dual-homed host.

Software and hardware interfacing merchants and credit-card authorization networks. [Mattila]

1. In a communications network, a network node equipped for interfacing with another network that uses different protocols.
Note 1: A gateway may contain devices such as protocol translators, impedance matching devices, rate converters, fault isolators, or signal translators as necessary to provide system interoperability. It also requires that mutually acceptable administrative procedures be established between the two networks.

The LPG is a signaling and media interconnection point between the NG9-1-1 Emergency Services Network and legacy PSAPs. It is responsible for interworking the SIP signaling to the Traditional MF or Enhanced MF (E-MF) signaling supported by the legacy PSAP and is responsible for providing emergency services-specific processing associated with transfer requests to and from legacy PSAPs and for processing… (Read More →)
