Gigabit DHE is a 1-Gigabit bandwidth aggregator for the distribution loop. GB DHE is related to the RAMNET system. It interfaces to the Distribution Loop at 100Mbps and the Area Loop at 1-Gigabit. It is an element of the Area Loop, which acts as the Head End for the Distribution Loop. In case of loop failure, the DHE automatically selects the redundant path for communication. The Distribution Loop break and establish condition is detected within 200msec
Multiple DHEs can be connected in a loop topology to realize large network. The hardware and firmware is field programmable and can be upgraded from remote head End. Multiple MB-DSLAMs can be connected in a loop topology to realize large network

Easy to Install and Use
The unit is wall mountable with an easy self-descriptive installation guide note and wiring guide note.

Simple Troubleshooting
Get at-a-glance network status information from front-panel diagnostic LEDs, including a unique Failure Alert LED.

Compact Design
Save valuable small-office space with compact, ergonomic, and robust design.

Easy Monitoring
The WICE.MAN network application helps user to pinpoint all activities and status of the network and the elements used in the network.
