AN-FE1/FE1+ETH/AC

2 x framed E1 Sub E1 & and Main E1 to Ethernet converter. AC 96 - 260- V AC, 75/120 ohm impedance for E1 port.

AN-FE1/FE1+ETH/DC

2 x framed E1 Sub E1 & and Main E1 to Ethernet converter. DC 48V, 75/120 ohm impedance for E1 port.

Description

AN-FE1/FE1+ETH Interface Converter 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 device can be cascade connected to the same devices or the other related devices, each node uses several timeslot, and the 32 timeslots in E1 make it possible that the data from 31 nodes can be collected to the center node to be transmitted by 2M channel. The device is suitable for the service transmux in one E1 from several nodes with little transmission services and it increases the utilization rate of the E1 resource and reduces the quantity and simplifies the structure of the network. It can be used to connect the down E1 circuit to public E1 network, or connect the down E1 to PABX or other E1 devices through timeslot drop/insert then to public network. The down E1 and ETH are absolutely physically isolated.
