Fast Ethernet In-band Managed Converter

Fast Ethernet In-band Managed Converter

The FRM220-10/100i is a 10/100Base Ethernet to 100Base-FX fibre converter designed for central and remote applications. With advanced features like bandwidth control, this media converter is targeted for customer premises equipment in metro LAN, campus, enterprise and FTTx applications. By offering in-band management, this converter can be completely controlled and monitored from a centrally located managed rack controlling all converter settings including band-width control, duplex, and speed configuration. This media converter is completely transparent to Layer 2 and Layer 3 protocols including IEEE 802.1q, VLAN tag, Q in Q, STP, IPX, IP, etc.

When used on its own the unit operates as a 'standard' 10/100 converter. When used in conjunction with the NMC management card access to management and monitoring features becomes possible. Additional features such as forcing the speed and duplex, or the ability to rate limit traffic traversing the converter become available. The remote FRM220-10/100i(s) can also be configured via an embedded communications channel contained within the fibre link. Link loss forwarding and enabling or disabling the converter can be configured too as well as monitoring the health and status of the copper and fibre ports on both the local and remote converters. Digital diagnostics are supported in SFP cards showing further characteristics of the optical link.
