Power Over Ethernet
LAN Switch
G4680 offers a solution for extending traditional E1 services transparently over Ethernet network. The device converts the data stream coming from its TDM ports into Ethernet packets that are encapsulated using TDM over IP method and forwarded over Ethernet, G4680 offers point to point or point to multi-point synchronization for voice/leased line applications. G4680 also provide 4 Gigabit Ethernet ports for connectivity to IP networks and Ethernet devices. Management is performed locally by a terminal, or remotely via Web, Telnet, or SNMP.
Several versions of the unit are available, offering different of impedance types and different number of the E1 ports to suite different application requirements.
