Network Interconnection
Public Network Connectivity
Interconnection of sites generally requires the use of public Wide Area Network (WAN) services (ADSL/FTTC/3G4G). The WAN router provides the interconnect between the LAN and the WAN. These devices can be quite complex, and their performance and features vary considerably, as do their price.
Product Selection Criteria
