1. About the EMC-LAN-EX LAN Extender
1.1 Description
The LAN-EX transmits high-speed Ethernet over long distances on STP (
Shielded
Twisted Pair) which is particularly relevant for elevator hoistways which are electrically
“noisy” (both electrostatic and electromagnetic) compared to standard LAN Extenders
requiring unshielded wiring which would be significantly more susceptible to noise.
The basic LAN-EX modem operates in pairs in bridge mode, each with one RJ45
Ethernet port and one RJ45 (2-wire) VDSL port transmitting up to 100Mbps of
symmetric data over copper wires. Symmetrical or asymmetrical transmission can be
selected with bandwidth up to 100/100 Mbps (line rate) within 1,000’ (~300m) or
10/10 Mbps for 3,000’ (~900m) connections. Gbps models are available wherever more
bandwidth is required.
One-way or even two-way video streaming
and
telephone voice can be multiplexed to
share the same pair of wires although, if available, separate pairs reduce
troubleshooting complications.
In summary the LAN-EX provides a reliable, cost-effective method to deliver Ethernet to
an elevator over standard traveling cable shielded twisted pairs.
1.2 Key Features
Cost-effective long-distance Ethernet bridge
Asymmetric mode provides the highest line rate with directional control via DIP
switch
Symmetric mode provides up and down transmission as would be required for a
camera
and
a media player
Supports “flow control” with Pause Frame or Back Pressure
Selectable profiles are available for maximum data rate to suit different
requirements, for example less error checking and high or lower signal to noise
ratio (SNR).
19-inch rack mountable (2U)
Ease of setup and operation
LEDs for diagnostics
