Optical multiplexer ToPGATE-4E1-2FG

Support for CSFP (Compact Small Form-factor Pluggable) modules. 2 optic-fiber lines can be connected through a single CSFP module
Opportunity to view IDProm and DDM (Digital Diagnostics Monitoring) of SFP/CSFP modules
Dying Gasp
Transmission of 4 structured or unstructured E1 streams through data network without quality deterioration
Unique algorithms of frequency recovery which provide stable operation on real networks
Unified interface with ToPGATE series devices for combination of 100M, 1G and 10G networks based on cooper, optical and wireless technologies
Local traffic mirroring
MVR (Multicast VLAN Registration) – multicast VLANs registration, which allows to transmit multicast stream in a single VLAN, while end users are capable to obtain it being in different VLANs.
Support for RSTP protocols for networks with complicated topology with redundancy, e.g. ring with spurs, tree
Support for SNMP, Web, Telnet, SSH, RADIUS, TACACS+
Local and remote management and diagnosis
Opportunity to control devices through Eltex-EMS management system
