Glossary

A Gateway (GW) in telecommunications context is a boarder element that bridges between one network to another translating between transmission formats and communication procedures (protocols). A typical GW will bridge between an IP based network to a Public Switched Telephone Network (PSTN) or between one IP based network to another (IP-to-IP Gateway). A Gateway may also perform translation between different audio, video and data formats. Even though the protocol and media functions may be physically decoupled they are logically tightly coupled.
