1 to 16 Ports E1 HDLC Interface Converter DNT Series

Global Tech’s DNT series EoP Interface Converter adopts inverse multiplexing technologies, and supports 32M maximum Ethernet bandwidth.  DNT Interface Convert can combine multi Ethernet channels for 10M/100M Ethernet service transmission and supports 1 or maximum 16* E1 channels combination.

The Multi-E1 Bridge can cooperate with Ethernet Switch or Hub directly and utilize current adequate E1 resources to extend the Ethernet transmission distance and coverage range. The Interface Converter can deploy in LAN inter connection, Centre Office and CPE inter connection, Video On Demand, Remote Surveillance, and E1 tributary card connection in Switches.

In this Series we are avaible in 1/4/8/16 E1 to Ethernet(Optional for 4ETH).

l Available E1 channel quantity auto detection and bandwidth allocation. The E1 sequence number and quantity can cooperate flexibly and asymmetrically at both ends.

l Realize 4 Ethernet channels over 1 up to 16 E1 channels inverse multiplexing, support TAG VLAN setting and JUMBO frame transparent transmission from IEEE 802.1Q, and cooperate with Ethernet switch with VLAN function.

l Support E1 channel delay differentiation detection function and 220ms maximum E1 channel delay differentiation.

l Automatically disable the E1 channels with LOS, AIS, LOF alarm, and intelligently enable them once the alarms resolved.

l RS232 Serial and SNMP based Network Management System, to monitor and configure the Network Element operation status.
