DONGWE DW-PC8E1-E adopts inverse multiplexing technology that transmitting 1-4 10/100BaseT over 1~8 E1 links. Employing Ethernet-over-PDH technique, it allows the transport of native Ethernet frames over the well-established PDH telecommunications infrastructure. This enables carriers to make use of the extensive legacy PDH and TDM equipment to provide new Ethernet-centric services. It can be used for interconnecting Wimax Base Stations and IP exchanges (MSAN & MSAG) de-ployed at remote locations to the aggregation Switches through E1 interface. It supports flexible configuration if 1~8E1 links, auto-detecting the number of E1 and selecting the available channels.
Product details :
Be fully compatible with the following specifications: a) IEEE 802.3, b) ITU-T G.703, c)
ITU-T G.704, (G.7041, G.7042, G.7043) d) ITU-T G.823, e) ITU-T G.8040.
Supports Dynamic Ethernet MAC address (4096) with local address filter function.
Support and transparently pass all the protocols that exist in 10 Base-T, 100 Base
–TX Ethernet networking system.
Map 100Base-TX or 10Base-T Ethernet data into 8E1 channels, and vice versa.
Learn automatically the MAC address in the connected LAN and only transmit the destination address of the frame in another LAN.
Extend the bandwidth to 16.384M using 8-E1 channels and 8.192 M while using only 4-E1 in the same 8E1 to Ethernet Converter over Telecom opearator’s SDH/PDH network before aggregation to a switch.
The converter shall provide the facilities to auto-inspect and auto-restore affected E1 channels without interrupting the data traf-fic.
Auto-detect the valid E1 channels and auto-balance the data flow among the valid E1 channels.
provide remote and local E1 Loop test when it has LOS and LOS alarm, and inform the remote end simultaneously.
provide remote and local E1 Loop test function through indicators.
provide comprehensive LED alarm/working status indicators for E1 and Ethernet interfaces.
provide NMS function, the NMS is based on TCP/IP network and shall support SNMP V1, V2 / V3
protocol which it monitored through NMS GUI and WEB based both.
Input Power supply: DC -48V and should be operational from -45 to -57 DC Volts and also should support AC 180V~240V.The converter shall consist at least one earthing (grounding) port.
support Channelized and Non-Channelized E1’s .
support to configure by Console port(RS-232)
The NMS port in the equipment is 10/100Base-T Management port and support TCP/IP.
Power supply: AC220V/DC-48V/DC+24V are optional
AC220V： insert AC220V power line directly
DC-48V： insert AC220V power line directly, the positive and negative charges can connect mix, -45V ins grounded, GND is connected to 48V.
