"Convergence at the SOHO"
BB-4202 allows users to route voice and fax calls over an IP network to lower telephone toll charges. BB-4202 is a two-port model convenient for connecting a fax machine as well as telephones on the VoIP system.
BB-4202 is designed to operate in a number of network environments. BB-4202 can terminate connections on a company intranet, serve as a gateway to the public Internet, or as an access point to VoIP service provider networks.

STANDARD-BASED
BB-4202 supports the ITU-T H.323 standards. BB-4202 will interwork with any vendor products complying with the H.323 specifications. BB-4202 is compatible with any standards-based PBXs, key systems (KTS), and analog telephones. BB-4202 can be connected to a PBX or KTS CO port and a standard RJ11 port on an analog phone. For IP networking, existing routers, hubs, and other devices can be used with the BB-4202 system. BB-4202’s LAN port interfaces with a 10 base-T local area networks. BB-4202 can be remotely managed via the industry standard Simple Network Management Protocol (SNMP), via Telnet or via a Web interface over the Internet.

PSTN BACK UP
Against power failure or IP network problems, BB-4202 has a PSTN backup function that automatically enables the user to make calls via the regular telephone network. Thus, at no point will BB-4202 users be without critical phone services.
