Overview MEL-FE1 The Ethernet timeslot drop/insert device is
an economical digital access solution to framed E1
and partial E1 network service. The device can drop
several continuous timeslots from the up standard ITU-T
G.703 E1 interface as Ethernet service, and the remainder is
straight-through from up E1 to down E1. The down E1 and ETH
are absolutely physically isolated.
Features ◆ high quality Ethernet bridge/extension
◆Fully compatible with IEEE 802.3/Ethernet v.2 ◆
Clock mode: The output clock of up E1 is as dropped
clock from input up E1 signal. Line clock in down
line (synchronized to down received clock)/main
clock (own crystal clock) (optional). ◆
WAN line data rate: 2.048M ◆
Line code: HDB3 ◆
