aggregator

Like its synonym concentrator, an aggregator is any device that serves multiple other devices or users either with its own capabilities or by forwarding transmissions in a more concentrated and economical way. A remote access hub is sometimes referred to as an aggregator. A typical aggregator or remote access hub is a device that handles incoming dial-up calls for an Internet (or other network) POP and performs other services. An aggregator may be able to handle up to 100 dial-up modem calls, support a certain number of Integrated Services Digital Network connections, and support leased line and frame relay traffic while also functioning as a router.
