LambdaDriver^®– 2 x Analog E&M Voice and 2 x Dry Contact
over Fiber/Lambda -TDM Module (EM2009-2EAM)
Overview
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 configured to operate in trunk mode or signaling device mode.
Signaling types selectable via dip-switches for local operation and can
be configured remotely.
