FM4200 converging voice and data applications across an E1 2Mbps G.703/G.704 leased line

This application shows a pair of FM4200 units connecting together 2 sites with multiple independent applications via an E1 G.703 2.048Mbps leased line, such as a BT Megastream-2 service. X.21 serial ports are often the most cost effective WAN port available on routers and other equipment such as video conferencing equipment, whilst PBXs have Fractional E1 G.704 interfaces. The FM4200 mutliplexes these different voice and data information streams together onto a single E1 circuit, and then demultiplexes them back out again at the remote site.

FM4200 being used to converge sub rate Nx64kbps services onto a single E1 2Mbps G.703 leased line

This application shows an FM4200 unit connecting multiple Nx64kbps sub rate services over a single E1 2Mbps G.703/G.704 leased line. In this way two sites in close proximity can be connected together via a cheaper leased line and share the cost of a single longer distance leased line thereby enabling considerable savings. Multiple FM4200 units can be cascaded in this application through connection via the E1 drop port.

LM1100 SNMP Enabler used with Management Datalink to manage a pair of FM4200 units

This application show a remote network management centre controlling the head office FM4200 via an LM1100 SNMP Enabler card allowing comprehensive management access including the full range of configuration changes, diagnostics and status analysis using either SNMP or Telnet, including SNMP traps. In this application a remote management datalink has also been enabled to the remote FM4200 unit, allowing remote SNMP and Telnet access into this unit.

The FM4200 offers conversion between an X.21 or V.35 serial interface and an E1 line interface with BNC or RJ45 connector options. An E1 drop port is also supported for connection to a PBX or E1 router, or alternatively cascading onto another FM4200 unit.

Fractional operation allows a number of 64kbps timeslots to be active, up to a maximum of 31 timeslots for a single E1 line. If timeslot 16 is bypassed, then a maximum of 30 timeslots (channels) can be accommodated between the 2 user ports.

The FM4200 has several LEDs for displaying current status, plus comprehensive configuration and diagnostics via a menu driven user interface.

It is possible to connect the FM4200 to EIA-530 or RS-449 equipment using conversion cables.

Using a dedicated management timeslot pairs of FM4200 units can communicate with each other, allowing configuration and status checking of the remote unit.

The optional Metrodata LM1100 SNMP enabler permits remote management via either Telnet or SNMP.
