Mediatrix 4401 1 Port ISDN BRI Gateway
The Mediatrix 4400 Digital Gateways allow enterprises to lower communications costs over any IP link. The units feature ISDN BRI interfaces. They provide an ideal solution for enterprise voice applications or for connecting to a service provider's broadband access.

Product Overview
Designed specifically for enterprise applications, the Mediatrix 4400 digital gateways make use of existing broadband access equipment to connect to any standards based VoIP network.
The Mediatrix 4400 digital gateways meet the requirements of enterprises that want to connect their ISDN equipment, such as PBXs, through a BRI interface to an IP network or as a gateway to the PSTN.
Mediatrix 4400 digital gateways provide transparent ISDN port extensions over an IP network. The remote ISDN terminals can be managed centrally and benefit from PBX services such as calling groups and voice mail.
