AHE Module

Gigabit AHE is a 1-Gigabit bandwidth aggregator for the distribution loop. GB AHE is related to the RAMNET system. It interfaces to the Area Loop at 1-Gigabit and the Gigabit switch/server link at 1-Gigabit. It acts as the Head End for the Area Loop. In case of loop failure, the AHE automatically selects the redundant path for communication. Area Loop break and establish condition is detected within 100msec.
Multiple AHE can be connected to a Gigabit Switch to realize large network. The hardware and firmware is field programmable and can be upgraded from remote head End. Multiple AHE can be connected in a loop topology to realize large network.
The Loop under each AHE will be made by inserting DHE within the Lower side of each AHE.
