The Total Access 900/900e products are an ideal solution for creating a multisite IP network providing dynamic voice and data services. The Total Access 900e located at the host site with Total Access 900s at multiple remote locations allows SMB and distributed enterprise users to interconnect their legacy TDM-base voice equipment over an IP Wide Area Network (WAN). Each location can have a PRI, T1 Channel Associated Signaling (CAS), or FXS connection from an existing PBX or key system, saving on costly recurring toll charges while creating a robust, dynamic voice network.
