2 Analog E&M Voice + 2 Dry Contact

The LambdaDriver EM2009-2EAM is a TDM over Ethernet module that uses advanced TDM technology to transport 2 separate Analog E&M voice trunk circuits and two Dry Contact ports over a 1GE (Gigabit Ethernet) fiber/lambda interface for transmission to a remote location. Analog trunks connect systems such as PBX to a Central Office (CO) or to a network using the E&M signaling method. E&M signaling refers to one side being the trunk circuit side and the other side being the signaling unit side. Usually, a PBX is the trunk circuit side and the CO / Network is the signaling unit side.

The EM2009-2EAM incorporates 2 RJ-45 independent Voice ports featuring 2/4 wire voice interface and E&M signaling. The E&M signaling method supports all interface types I, II, III.IV and V. The module can be confi gured to operate in trunk mode or signaling device mode. Signaling types selectable via dip-switches for local operation and can be confi gured remotely.
