The Metrodata FM4200 DSU is used as a drop/insert multiplexer to mix voice and data traffic on a single E1 2.048Mbps link. The FM4200 provides a fractional E1 n*64Kbps drop port for the PABX equipment, and remaining E1 service bandwidth is allocated to the X.21 or V.35 port to carry traffic to/from a bridge or router connected to a LAN.
Front: FM4200 E1 Multiplexer
Rear: FM4200 E1 Multiplexer
he FM4200 can be used at either end of the Wide Area link. Error conditions and usage statistics are gathered and stored by the FM4200. Unit set-up is done via a comprehensive menu system which is accessed via a local or remote terminal.
The optional Metrodata LM1100 SNMP Enabler permits management via a LAN using an SNMP system.
