Router Option
User Manual
1 INTRODUCTION
This user manual describes installation, configuration and operation of the
Echo LANlink Multiplexer Router option, and must be referred to in
conjunction with the Echo LANlink Multiplexer User Manual.
The Echo LANlink is an E1 time division multiplexer (TDM) operating at
2Mbps compliant with both EUROPEAN and UK G.703 communications
standards. The Router Option card adds the capability of connecting two
Local Area Networks (LANs), via the E1 communication link, using some or
all of the link bandwidth.
A Router Option card needs to be installed inside the Echo LANlink at both
ends of the communications link. Each Router examines addressing
information on each LAN, and on recognition of an address on the distant
LAN, forwards the frame via the communication link, thereby linking the two
LANs together (see Figure 1).
