The EXMUX 3500™ provides a simple one-box solution that eliminates the need to run parallel voice, serial and IP data networks, converging two important traffic types onto one communications infrastructure. This new innovative concept offers a cost effective and feature rich solutions that now bridges the gap between the old TDM legacy world and the new modern IP world.

The EXMUX 3500™ can support any network topology such as linear, star, rings and mesh setups. The device uses the latest TDMoIP technology and an intergraded Layer 2 Managed Switch, which allows the unit to support legacy interfaces such as T1/E1, RS-232, RS-485, RS-422/RS-530, V.35, X.21, G.703, C37.94, and various voice interfaces, along with native IP solutions. A two wire telephone service channel is incorporated to provide in-band voice communication to any EXMUX 3500™ connected to the network. Latency can be as low as 5ms. In addition to the low latency, designed into the EXMUX 3500™ is a distinctive “Hitless Switching” mechanism that allows the device to recover from a path failure without losing a single data bit, making it ideal to run critical real-time applications such as SCADA,Teleprotection and Relaying over an IP network.

The EXMUX 3500™ comes with an advance visual graphical Network Management Software (VNMS) for Operations, Administration, Maintenance and Provisioning (OAM&P). The VNMS is intuitive and user-friendly, making configuration, channel mapping and diagnostics virtually effortless.
