DCEFRM220-AFOM01 is a modular design for E1/T1 + Fast Ethernet
multi-service to fiber PDH multiplexer.

DCEFRM220-AFOM01 provides E1/T1 transmission transparently, pure 100Mbps Fast Ethernet simultaneously.

The fiber optic line gives you the options to choose from most popular fiber cabling connectors such as, ST, SC, FC or SFP-LC.

Both multi-mode and single mode models are available as well as BiDi which allows bi-directional transmissions using only a single fiber cable, With SNMP and Web-based management in the FRM220, the Network administrator can monitor, configure and control the activity of each card in the chassis.


please note you may need to install a T-1 cross over
cable if the remote devise is DTE interface
view using a cross-over the cable on the remote side
