Ethernet over E1 / FE1 Converter

VCL-Ethernet over E1 (FE1)

Product Overview

Orion Telecom Networks Inc. offers its Ethernet over 1 E1 converter. The 10Base-T Ethernet interface to 1 E1 interface converter which offers a channelized E1 and 10Base-T interface conversion. This equipment offers electrical level conversion between 10Base-T Ethernet interface and a G.703 / E1 (or fractional E1) interfaces.

The VCL-Ethernet over E1-E1/10(100) Base-T Interface Converter provides the user with Ethernet over E1/E1 conversion enabling the user to transport Ethernet data over an E1 link. The equipment be always installed and used in pairs, with one terminal being installed at either end of the network.

The VCL-Ethernet over E1-E1/10(100) Base-T Interface Converter is an Ethernet extension device utilizing TDM telecom infrastructure (the telecom network of E1s, or of PDH, SDH and E1/E3/SDH microwave etc. carrying E1s). It converts the Ethernet data into E1 frame format for transmission over the existing TDM (E1) links and then re-converts the E1 back into Ethernet data the far-end terminal, to BRIDGE two Ethernet LANs over the existing E1-based telecom network. The device can effectively utilize the redundant bandwidth of telecom operators existing TDM network to transport Ethernet data with low investment.

Applications

The equipment may be used for the following purposes:

Bridging Ethernet LANs over existing TDM (E1) telecom network
Extending Ethernet networks utilizing TDM (E1) landline based telecom infrastructure
Using telecom network of E1s/PDH/SDH microwave etc. carrying E1s to transport Ethernet data

Features

The maximum transmission rate of Ethernet data over E1 links is 2.048Mbit/s
E1 supports three working modes of transparent transmission, framed (CCS/PCM 31) and multiple framed (CAS/PCM30)
Allows transparent transmission of super-long frames in 1528 bytes (without CRC) and supports Ethernet switches with VLAN function
Automatic Ethernet negotiation function. Supports 10M/100M and working modes of both full-duplex and half-duplex
Available with MAC address list filtration, learning and updating functions
Available with auto-resetting function. When network port stops receiving or sending data for about 8 seconds, the auto-resetting circuit will be able to start automatically, to reduce and maintain workload for the system
Equipment supports two working modes of internal clock and network clock
Supports RLOOP (E1 port external loop-back) function
