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.

1 slot wide – can be used in all LD chassis
Applications
Analog trunk circuits connect automated systems, such
as a private branch exchange (PBX) and the network such
as a central office (CO) in a point-to-point standalone
(direct) interconnection
E&M and Dry Contact Control over Fiber for Electricity
Networks
Signaling of E&M and Dry Contact over DWDM networks,
integrated -multiple chassis span - interconnection using
one DWDM channel.

Dry Contact Interface:
Inputs - Sense A and Sense B - Dry contact Normally open switch
Outputs - Center, Normally Open and Normally Closed relay contacts
Closing of Sense inputs (connect Sense A to Sense B) is transmitted to the remote side
and used as trigger to change the state of its dry contact relay
Additionally, two controlled dry-contact interface ports are
available on-front-panel, each port providing N/O (Normally Open),
N/C (Normally Closed) and Common connect option. The switch
over from one state to another is activated upon sensing the local
or remote state of two HW inputs – SEN A and SEN B.
TDM Loopback, Ethernet Loopback including MAC DA/SA
swapping, integrated BERT generation and test (G.821), and
Ethernet Sniffer provide advanced troubleshooting capability.
Performance management is possible by the available Ethernet
port Statistics, CRC errors monitoring, and more.
The trunk port is a 1Gbps (GE) SFP based interface that can
accommodate various types of hot swappable pluggable SFPs e.g.
Multimode , Singlemode, BX (Single Fiber), CWDM or DWDM.
Due to its advanced internal architecture, the module provides
extensive monitoring and control features.
Ethernet header editing function permits user controlled definition
of the traffic over the GE trunk port. Layer 2 (MAC) addresses, VLAN,
etc., and Layer3 (IPv4) parameters such as IP address, UDP port etc
are user configurable.
