Multipurpose service routers ESR-20 and ESR-21 has been developed in compliance with requirements of energy and oil-and-gas industry. The devices allow to solve a wide range of tasks relating to network safety of carriers, large financial organizations and huge market chains.
ESR-20 and ESR-21 service routers are designed to perform network data filtering by different criteria, to construct safety area of the network (Firewall), to organize encrypted tunnels between company's branches, to establish a remote connection of employees to an office and to provide redundant connection. The devices support advanced L3 features, redundancy/balancing of uplinks towards providers.
• High performance
• Passive cooling
• Compatibility with leading manufacturers equipment
• Hardware data processing acceleration
The main feature of ESR-21 is the presence of 3 asynchronous serial ports RS-232 that are capable to transmit data through wired and GSM modems used in energy and oil-and-gas industry. The ports might be used in AUX mode as well (the mode used for remote device management via Console).
