E1 transceivers

Models 4632/E1 stand-alone and 5632/E1 rack-mount fiber-optic transceivers convert an E1 (2.048-Mbit/sec) electrical signal into an optical signal capable of transmitting over 80 km. Both models have local and remote loopback capability for fault isolation. An optional redundancy switch that activates a hot standby channel is also available.
